DHT22 Temperature and Humidity Sensor

QUICK OVERVIEW

The DHT22 Temperature and Humidity Sensor is a highly accurate and reliable digital sensor for measuring temperature and humidity in various applications. It is an upgrade from the DHT11 sensor, offering improved accuracy and range, and is widely used in a variety of applications such as home automation, weather monitoring, and industrial control. The DHT22 uses a capacitive humidity sensing element and a thermistor to measure the relative humidity and temperature, respectively. The sensor provides a digital output via a single wire interface, making it easy to connect to a microcontroller or other digital circuit.
