5PCS DHT22 AM2302 Digital Temperature and Humidity Sensor, AM-2302 Temp Humidity Monitor Sensor Replace SHT15 SHT11 for Raspberry Pi

• 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.

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-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 AM-2302 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity composite sensor. It uses a dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that products with high reliability and excellent long-term stability Application range： HVAC, dehumidifiers, testing and testing equipment, consumer products, automotive, automatic control, data loggers, home appliances, humidity regulators, medical, weather stations, and other related humidity detection control. Package Included: 5 x DHT-22 temperature and humidity sensor
