Arduino Uno-ATmega328 P Microcontroller Based Smart Systems

Abstract

The paper reports two Arduino Uno-ATmega328 P Microcontroller Based Smart Systems used in the day-to-day activities of humans. The first is 3-Phase Induction Motor Protection and Parameter Monitoring. The tremendously developed and increased industrial sector demands reliability along with the continuous and uninterrupted operations of the industrial appliances. The robust and easy to control feature of the Induction motor makes it the most suitable motor in the era of industrial development. As there are large demands for production to be increased. Therefore, the instances of maintenance and breakdown must be avoided to keep the continuity in production. Protection systems play a very important role in keeping the machine operated continuously without damage. Here the Arduino Uno microcontroller is used to read the voltage, current, operating power factor, and phase sequence of the 3-phase ac supply of the motor. The predefined reference values are set in the microcontroller and based on the actual operating conditions the microcontroller takes the action to turn off the supply to the motor. This method is best suitable for small applications. As in small applications, the control of a smaller number of parameters is required. This project successfully protects the induction motor and the overall reliability of operation is maintained. The second system is the smart agriculture irrigation system. When it comes to agriculture, irrigation is crucial. Because India is known for its agricultural outputs, numerous ways for irrigating a farm field are based on personnel, water resources, and most significantly, water availability. So, in order to save both time and water, we propose a method in which manual labor is replaced with an automated system capable of autonomously irrigating fields without human intervention. Here is an automated system for a poly-house that includes a soil moisture sensor that detects the soil's moisture content and, based on that, the system operates the pumps and the irrigation process is carried out. Another parameter is the temperature within the poly-house, which will be sensed using a temperature sensor, and the temperature cooling mechanism will be activated. Android will serve as a user interface via which the user may manage the machine while also receiving information about their agricultural land.
