This design addresses the problems in traditional aquaculture environments by identifying dissolved oxygen, turbidity, and temperature as key environmental parameters for system regulation. An innovative aquaculture environment system that integrates sensor technology, automation technology, and wireless communication is constructed. The system uses AT89C52 microcontroller, DS18B20 digital temperature sensing module to detect water temperature, DS1302 real-time clock module to provide real-time time for the system, dissolved oxygen sensor to detect the content of oxygen dissolved in water, turbidity sensor to detect water quality, and relay module to simulate and control oxygenation operation. The microcontroller in the system analyzes the real-time information obtained by the detection device and controls the LCD1602 LCD display to display the information. Finally, through hardware function debugging, it was demonstrated that the system is capable of real-time detection and control of aquatic environment parameters, and can achieve remote communication between users and aquaculture environment systems. Overall, this system has certain application value and significance in the field of aquaculture.

Abstract:
The modern era is rapidly progressing in all sectors, including agriculture. Irrigation is a crucial aspect of agriculture, and in India sprinkler and drip irrigation techniques are used. But these processes are manually operated, which is timeconsuming and results in low productivity. The objective of this project is to design and develop a Microcontroller based Smart Irrigation System for Farms. The automation in the irrigation process of farms will minimize the costs and time consumption while promoting sustainable development with the help of IoT. This system can precisely utilize the water on the farm without any wastage. The System is designed to operate in Automatic and Manual mode. In automatic mode all the control of the system is handed to the AT89c51 Microcontroller, Soil moisture sensor connected to the AT89c51 MCU is used to sense the moisture in the soil and the motor is actuated accordingly. If the rain is detected by the Rain sensor which is also connected to the AT89c51 MCU, the motor is automatically turned off to avoid the access water in the farm. In manual mode, the motor can be turned on and off with the help of an Android app that is connected to the ThingSpeak IoT cloud. The temperature and humidity values from the Dht11 sensor in the farm area are also shown on the app interface. The system sends and reads the data from the cloud with the help of ESP8266 MCU which is connected through the Wi-Fi. As the System is connected to the Internet through Wi-Fi we can monitor and control the system from any remote area. We have used two controllers so that if any one microcontroller fails the other microcontroller runs the system smoothly

Abstract:
A radio-controlled (RC) aircraft is controlled remotely by a hand-held transmitter and a receiver within the craft. The working mechanism of such an arrangement designed using an AT89S51 microcontroller is reported in this chapter. The primary focus of the chapter is to describe the design of the interfacing of transceiver module with AT89S51 microcontroller and control the movement of the aircraft according to the instruction given remotely. The microcontroller reads the input given by the user and transmits the data to the receiver at the aircraft. The receiver module receives the transmitted signal and demodulates it and gives the data as serial sequence of bits at the output. The serial data are then given to the decoder which transforms the data from serial to parallel. This set of data is used to control motors and any related device. A special coding technique is used to secure the transmitted data.

Abstract:
A solar-powered omnidirectional wheelchair is implemented for physically challenged persons. The framework was mounted on the wheels that were connected with two direct current (DC) motors. The ratings of the battery and solar module were determined using system voltage (12V). A 7,805-voltage regulator was used to supply 5VDC to the AT89352 microcontroller. The microcontroller was programmed to provide a reference signal to the motor. The motor provides the needed torque to drive the wheels through interconnected relays. The relays are energized by the microcontroller and omnidirectional movement achieved through relays connected with microprocessor and micro switches, eliminating the need for joysticks and complex control mechanisms. System performance test result showed that the auxiliary solar power supply of the wheelchair increased the travel range by approximately 86% compared with that of a wheelchair powered by battery alone.
