Temperature and Humidity Control within a Customizable Range
In this video tutorial, we demonstrate how to build a temperature and humidity controller using a DHT sensor, Arduino Mega, character LCD, and a 4-channel relay. We show how to program the Arduino to monitor and control temperature and humidity within a customizable range. With step-by-step instructions, viewers will learn how to wire the components, upload the code, and use the serial monitor to observe temperature and humidity values.
