DORHEA 5PCS DHT22 AM2302 Digital Temperature and Humidity Sensor, AM2302 Temp Humidity Monitor Sensor Replace SHT15 SHT11 for Raspberry Pi
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•DHT22 main chip is AM2302 high sensitive temperature humidity sensor. Single-bus digital signal output, bidirectional serial data.
•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).
•The DHT22 is a reliable sensor for determining temperature and humidity. The output is serial as a digital bit sequence.The sensor is ideal to monitor the room climate or to build a weather station.
•Each AM2302 sensor is calibrated in a very accurate humidity calibration room. The calibration coefficients are stored in OTP memory in the form of programs that the calibration coefficients are invoked within the sensor during signal processing.
•Single-wire serial interface, the system integration becomes simple and quick. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it the best choice for all kinds of applications and even the most demanding applications. Products are 4-pin single row pin package, easy to connect.
