DORHEA 5PCS DHT22 AM2302 Digital Temperature and Humidity Sensor, AM2302 Temp Humidity Monitor Sensor Replace SHT15 SHT11 for Raspberry Pi
Description
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 AM2302 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 DHT22 temperature and humidity sensor
Features:
- 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.
