Summary of the Circuit

This circuit consists of an Arduino UNO R4 WiFi microcontroller board and a DHT11 temperature and humidity sensor. The Arduino UNO R4 WiFi is responsible for controlling the operation of the circuit and processing the data received from the DHT11 sensor. The DHT11 sensor provides ambient temperature and humidity readings. The Arduino is powered through its 5V pin, and it communicates with the DHT11 sensor through one of its digital pins.
