Description
DHT21 Digital Temperature & Humidity Sensor
The DHT21 (also known as AM2301)** is a high-accuracy, calibrated digital sensor for measuring temperature and relative humidity. It features a capacitive humidity sensor and a thermistor, with a digital output signal, making it perfect for microcontrollers like Arduino, ESP32, Raspberry Pi, and more.
More accurate and stable than DHT11, and with better range than DHT22, the DHT21 strikes a great balance between performance and price.
