Abstract:

The use of ultrasonic sensors, especially HC-SR04, in microcontroller projects is expanding thanks to its ability to accurately detect distance. In this final project, the HC- SR04 is connected to an ESP32 to measure the distance of an object and provide feedback in the form of sound when the object approaches the sensor within a certain distance. The HC-SR04 sensor works by emitting ultrasonic waves and measuring the time it takes for the waves to reflect back to the sensor. The ESP32, as the microcontroller connected to the sensor, processes this time data to calculate the object's distance

Abstract:

This research aims to design an early warning system to detect floods. This is motivated by flood disasters that often occur unexpectedly and without warning so people cannot make preparations to avoid these disasters. This research uses the wireless sensor network method to integrate several sensors and the Internet of Things in its monitoring. The purpose of this effort is to provide communities vulnerable to flooding with fast and accurate alerts, enabling remote and immediate communication during flood events. This research aims to create a prototype system that can replace the human role

Abstract:

Theft of premium oil in Tank Trucks is very frequent done by irresponsible people. In general, the tank security system uses only the seal on the door of the faucet, therefore the seal can still be duplicated. To overcome this problem, its security system needs to be transferred to an electronic system with premium automatic delivery system control using HC-SR04 ultrasonic sensors and push-button. The system will send the fuel level information (premium) with SMS and display on the LCD when the charging or distribution is complete. There are 3 (three) premium levels that will be applied to the

Flood is a common problem not only in India but worldwide and most of the water bodies are easily accessible to common people. At times it may happen that the weather conditions may change suddenly and the water bodies may become violent, resulting in a flood which can lead to loss of lives as well as livestock. Therefore, a rapid flood detection system that can reach a wide area such as the internet is necessary to minimize the effect sof disasters.

Abstract:

Floods are devastating natural disasters that frequently occur in Indonesia, particularly during the rainy season. The losses incurred by this disaster are significant, as it happened suddenly, leaving little time to evacuate valuables or move to a safer location. The financial and material losses, as well as the loss of lives, are overwhelming, as there is no early warning system in place to minimize the damage. However, a solution may exist in the form of an early warning system that uses ultrasonic sensors and microcontrollers to gauge water levels and alert the public of impending danger.

Sonar is a technology that uses the propagation of sound waves to detect the position of an object. Usually, fishermen use sonar to detect fish locations. The problem is that the price of sonar is still expensive, so not all fishermen can afford to use it. One of the devices that can be developed is the HC-SR04 module. HC-SR04 has simple components, and the price is cheap. The use of HC SR04 is still very minimal, so it is necessary to analyze the accuracy of its distance readings on various objects and conditions.
