Remote Climate Control in Real Time Using Arduino Microcontroller and Xbee Zigbee

Abstract

 Due to the growing demands for security and regulatory compliance, monitoring environmental indicators has become increasingly important nowadays. As a result, it is crucial to measure these factors. The conventional wired systems are unable to perform parameter measurements in remote locations. Therefore, the next generation of technology, like wireless technology, is required. Micro-Electromechanical systems (MEMS) technology has advanced, making small, inexpensive, low-power wireless modules available that function effectively in these settings. An Arduino-based DHT11 sensor-based automatic temperature management system is designed and implemented in this work. Temperature, humidity, a rain sensor to detect environmental occurrences, and Liquid Crystal Display (LCD) indicators to show how weather conditions affect the system under consideration. The results are provided by the DHT11 sensor, which measures the humidity and temperature of the surrounding space. Along with the measured value, the reference value is shown on the liquid crystal display (LCD). The Arduino microcontroller, which controls the system's processing, receives the sensor's measured value and assesses it against the established threshold. What happens is that the microprocessor activates the fan only when the measured room temperature and humidity are below the threshold value's lowest value. The fan is actuated if the detected room temperature exceeds the highest permissible threshold value.  If the observed temperature of the room is within the setpoint range, all loads are finally turned off. That suggests that the air is maintained at a consistent temperature and humidity level. The usage of an Arduino microcontroller, Xbee Zigbee, DHT11 sensor, Rain sensor, and Proteus software to monitor temperature, humidity, and rain utilizing wireless sensor network (WSN) technology. As a result, nighttime humidity parameter variation is greater than daytime variation. A wireless system like this will benefit industries like agriculture, healthcare, storage, etc.
