Summary of the Circuit
This circuit consists of an Arduino UNO microcontroller board interfaced with a DHT22 temperature and humidity sensor. The Arduino UNO is responsible for controlling the operation of the circuit and processing the data from the DHT22 sensor. The DHT22 sensor is powered by the 5V output from the Arduino and communicates with the Arduino through a single digital pin.
Component List
