WebDHT22/AM2302 Digital Temperature & Humidity Sensor is a low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It’s fairly simple to use but requires careful timing to grab data. WebMar 27, 2024 · The DHT22 sensor consists of a capacitive humidity sensor and a thermistor with a built in Analog to Digital (A2D) converter that uses a proprietary 1-wire … onss consultation
