DORHEA 5PCS DHT22 AM2302 Digital Temperature and Humidity Sensor, AM2302 Temp Humidity Monitor Sensor Replace SHT15 SHT11 for Raspberry Pi
Type Accuracy resolution 0.1 Humidity range Temperature range Humidity measurement precision ±2%RH Temperature measurement precision ±0.5℃ 4-pin digital output Long distance signal transmission Relative humidity and temperature measurement The DHT22 is a basic, 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 AM2302 digital temperature and humidity sensor is a calibrated digital signal output temperature
