<strong>Abstract:</strong> Water is essential in our life. Water has been proven to be essential for the smooth functioning of tissues, cells and organs in the human body. Water maintains body temperature, helps body to absorb nutrients, helps in moistening oxygen for breathing. Without water human body cannot function properly. Water is one of the most abundant resources on the planet, it’s been estimated that over 71% of Earth is filled with water. Amongst the 71% only 1.2% is said to be drinkable or clean enough to consume. For human, we can survive without food, but without water it is not possible. Most of our metabolic activities depends on consumption of water. Drinking clean water is really important for us in order to maintain a healthy lifestyle. Apart from drinking, water can be used for carrying several domestic chores like washing, cooking, cleaning etc. Water contamination affects us in a much larger way than we anticipate. It’s very important to check the quality of the water so that our health is not compromised. Water Quality can be measured by various parameters, including Temperature, Turbidity. So, we have proposed a way to test the water quality in the lively environment. The proposed system is a cost-efficient system and can be used anywhere. This helps in understanding the quality of the drinking water that we consume, and also to check if there is any contamination in the water.

Temperature sensing is a critical aspect in various applications, ranging from industrial processes to consumer electronics. Two commonly used temperature sensors are NTC (Negative Temperature Coefficient) thermistors and DS18B20 thermometer sensors. NTC thermistors are resistive devices characterized by a negative temperature coefficient, making their resistance decrease as temperature rises. DS18B20 sensors, on the other hand, employ a digital 1-wire interface to provide accurate temperature measurements in a wide range. Understanding the measurement and performance limits of NTC thermistors and DS18B20 sensors is vital for selecting the appropriate sensor for a given application, ensuring reliable and accurate temperature data acquisition. Implementing temperature measurements using NTC thermistors involves considering their characteristic curves, while DS18B20 sensors offer a digital output, simplifying interfacing with microcontrollers. The output from both sensors is typically in degrees Celsius, providing essential information for applications requiring precise temperature monitoring.

This Paper introduces a temperature detection system in beer fermentation. A temperature monitoring system with characteristics of bus topology structure is composed of industrial computer, temperature detector, bus converter, transmission bus and especially 1-wire digital temperature sensor DS18B20. Four-core cable is used to form a tree-like or star-like network, in which 54 digital temperature sensors existing on 18 fermentation tanks can be connected. The quantity of junction wires between temperature sensor and computer will be reduced greatly. Temperature detector provides power supply for bus converter and DS18B20 through Four-core cable. Because bus converter has used hardware fault detecting technology, the fault temperature sensor can automatically detach from the main bus and will not affect normal working of other sensor in network. So to solve the problem of a certain sensor or branch's damage causing the paralysis of entire bus. The length of detecting temperature bus can reach more than 500 meters. These all make system maintenance and expansion easy. The experiments show that this system is characterized by high intelligence, high-precision, capability of making temperature test on multi-points and compensating function. The method has a good applicable value to the temperature test.

Many commercial yogurt brands do not have a minimum total lactic acid bacteria count (107 CFU/g) due to long distribution with inappropriate storage condition. This leads local producers to produce yogurt. However, commercial yogurt maker machines commonly have a low capacity of 0.5 to 2 L. This study aims to design a yogurt maker machine with a capacity of 15 L with a temperature setting of 37 – 45 ℃. The design and flow system were conducted by arranging the electronic components consisting of 5V 4 channel relay, ESP32 module, DS18B20 temperature sensor, RTC, 12V fan (along with 12 VDC connecting components), 220V heater, 20×4 LCD and plugs (adapter) 220 VAC cable. The yogurt maker machine was evaluated for accuracy of temperature readings (DS18B20 sensor and thermometer), response to incubation time and plain yogurt making. The T-Test was used to compare the differences between the two types of sensors measuring instruments. The results showed that the accuracy of temperature readings using the DS18B20 sensor was better than a thermometer, with a distance scale of 0.35-0.75 ℃ (P-value ≤ 0.05). Temperature testing using milk can be carried out with a temperature range of 37-45 ℃ for 12 h. Keywords: DS18B20, Temperature, Yogurt maker machine, Sensors

Therefore, they need to be they need to be taken care for in a baby incubator that will protect premature babies. An incubator is critical in the survival of premature newborns. Temperature management is one of the most important roles of a baby incubator, as it is essential to create thermo-neutrality in an infant's body. The purpose of this study was to analyze the temperature sensor in an infant incubator using proportional and derivative controls. To obtain a stable and precise temperature, this temperature sensor complies with hospital infant incubator standards. This study used the LM35 and DS18B20 temperature sensors and used the Atmega 2560 Microcontroller where the temperature will also be displayed on a computer using serial communication. Temperature data were obtained based on the measurement results at all set points on the LM35 sensor. In this case, the rise time is 6 minutes 20 seconds, the average overshoot is 2.2°C, and the time to reach steady-state status is 25 minutes. Meanwhile, on the DS18B20 sensor, the average rise time is 6 minutes, the overshoot is 1.2°C on average and the time to reach a steady-state is 23 minutes. It can be considered that the DS18B20 sensor is superior to the LM35 sensor because it has a faster average rise time and steady-state and the overshoot on the DS18B20 sensor is still within tolerance limits.

Hydroponics is a method of growing plants without using soil media. Some vegetables such as spinach are more suitable to be planted during the rainy season with a cool atmosphere, and some other vegetable crops have different temperature requirements so that environmental temperature monitoring and planting media are very important in the hydroponic method of planting. Temperature is a condition that can be measured using a temperature measuring device called a thermometer. The DS18B20 sensor is one of the sensors that can be used to measure water temperature. In this study, the LCD Matrix which has been connected to Arduino displays data from temperature sensors installed at several measurement points, namely on the storage tube at the bottom and surface and in areas close to the planting media. The temperature generated by the system is then validated using a mercury and alcohol thermometer. The use of a microcontroller can help store temperature changes from time to time and can be displayed again. This makes temperature monitoring activities more effective and efficient.

In cultivating freshwater fish, especially tilapia, water quality is a very important factor and influences the survival of the fish being farmed. Several parameters that must be considered in improving the development of tilapia fish are temperature and pH of the water. So, a water quality monitoring system is needed to be able to assess these parameters simultaneously in one time (real time) to maintain the quality of fish cultivation. The system designed for monitoring water quality uses a pH sensor with a 4502C module and a Ds18b20 temperature sensor which is then processed using an Arduino Uno so that it can be seen on the LCD. The results of designing a temperature and pH monitoring system carried out for three days in tilapia ponds obtained an error rate in measuring the pH of pond water of 0.87% on the first day, 0.94% on the second day, and 0.79% on the third day. Apart from pH measurements, the pool temperature was measured using a comparison of two Ds18b20 temperature sensors with research results showing the highest temperature measurement at 12.00 WIB was 30.25˚C for three days.

The shifting lifestyle trends towards prolonged periods of sitting have led to an increase in health issues such as stress, depression, and even hypertension. In the pursuit of maintaining health, therapy, particularly shower therapy, has become a popular choice for its perceived ability to provide warmth, relaxation, and alleviate fatigue. However, questions arise regarding whether the water temperature in shower therapy changes as water flows at specific rates and how this might influence the therapy's effectiveness. This research aims to observe whether the water temperature in shower therapy is affected by the flow rate using the DS18B20 temperature sensor. The method involves measuring the water temperature at rest and while it flows at various flow rates. Water flow is controlled using a dimmer on the booster pump, while temperature measurements are taken using the DS18B20 temperature sensor and water flow meter sensor. The test results indicate that water at temperatures of 38-43°C flowing through pipes experiences an average temperature decrease of approximately 1.53°C. However, the temperature decrease does not exhibit a linear relationship with the flow rate. These findings suggest the possibility of other factors, such as the surface area of the conduit (pipes), influencing the temperature reduction in shower therapy. Hence, further research to examine the impact of the surface area of the conduit on the temperature reduction in shower therapy is warranted to obtain a more comprehensive understanding.

Conflagration is an unpredictable tragedy. It may occur whether in the woodland areas or in the residential areas. Typically, it would only be recognized if indeed the flames spread and the smoke intensified. This study aims to detect fires using the MQ-2 smoke sensor, DS18b20 temperature sensor, and fire sensor. Using Arduino Uno as the controller, this system’s output is in the form of an alarm buzzer, Short Message Service (SMS) information using SIM800L, and an automatic fire pump. This system operates to detect the temperature shifts, the smoke concentration and the existence of a fire point which triggers an alarm in the form of a siren if two out of the three sensors are activated. It, then, sends information by Short Message Service (SMS) and automatically triggers the pump as the result. The fire sensor can detect hotspots with a maximum distance of 80 cm and the DS18b20 temperature sensor has an average reading error of 0.27 ° C with a maximum reading error of 0.5 ° C. The MQ-2 smoke sensor can detect smoke where the change in smoke concentration is directly proportional to the sensor output voltage. There are three conditions to determine fire conditions, namely the temperature sensor reads more than equal to 55 ° C and the fire sensor is active, or the temperature sensor reads more than equal to 55 ° C and the smoke sensor reads more than equal to 1000 ppm, or the fire sensor is active and smoke sensor reads greater than equal to 1000 ppm.

Precision agriculture in the Internet of Things (IoT) integrates different technologies able to raise crop productivity, optimize resource efficiency, and accelerate decision making. However, the adoption of this technology is usually costly, affecting the acquisition by the farmers. Thus, the objective of this work was to develop and evaluate low-cost hardware to obtain data in a hydroponic system via IoT. The experiment was conducted at the Pici Campus of the Federal University of Ceará and split into three distinct stages. Firstly, the DS18B20 temperature sensors were calibrated in water, using the KR380 infrared thermometer as a comparison method. For the second step, when the hydroponic system was installed, the water temperature was monitored in the channel and not in the solution reservoir. In this same phase, the quality of data sending and receiving was investigated. In the third step, the sensory data were analyzed with those obtained by the local Meteorological Station. The calibration results revealed that the DS18B20 sensor has reasonable accuracy and excellent agreement and reliability between data. As for receiving and storing, only 6% of the total data was lost.

As a country rich in fish species diversity, Indonesia was ranked as the fourth largest exporter of ornamental fish in the world from 2016 to 2019. Ornamental fish is one of the potential commodities. However, crop failure due to uncontrolled water quality such as rising ph levels is a problem that needs to be solved. As a solution, this study builds a LoRaWAN-based IoT system to be able to monitor ph, tds, and pool water temperature levels of koki and molly fish pond from anywhere and anytime through a mobile application. The sensor node uses a Heltec Lora Wi-Fi 32 v2 microcontroller that supports LoRa technology and uses the DS18B20 sensor as a temperature sensor, and a DFRobot sensor to measure ph and tds. From the test results, the accuracy of each sensor is quite good with an average error of 0.35 for temperature sensors and 0.37 for ph sensors, as well as an error percentage on tds sensors of 1.5. From the results of the implementation, the ph and temperature values in the koki fish and molly fish pond are quite good as habitats, but the tds value of pond water is quite high.
