NIHAKA DHT22 Digital Temperature and Humidity Sensor Module with Cable for Arduino 1 Pc Temperature Sensor and Controller Electronic Hobby Kit

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.>>>>Specs: 4-pin package, Ultra-low power., No additional components., Excellent long-term stability., All calibration, digital output., Completely interchangeable., Long distance signal transmission., Relative humidity and temperature measurement, Type: DHT22/AM2302., Accuracy resolution: 0.1., Humidity range: 0-100%RH., Temperature range: 40~80?., Humidity measurement precision: ±2%RH, Temperature measurement precision: ±0.5? <<<<<<<< 4 Pins Sequence Number: Pin1-VDD(Power 3.3V-5.5V); Pin2-SDA, serial data interface, two-way interface; Pin3-NC, no connect; Pin4-GND(Ground).>>>>>>>>Packege Includes: 1 x DHT22 Digital Temperature and Humidity Sensor
