DHT22 Digital Humidity Sensor AM2302 Monitoring Sensor Module Electronic Building Blocks Compatible Blackboard with Wire for Indoor Humidity Real Time Monitoring
DHT22 Digital Humidity Sensor AM2302 Monitoring Sensor Module Electronic Building Blocks Compatible Blackboard with Wire for Indoor Humidity Real Time Monitoring
1.Features High-precision Measurement: Compared with sensors such as DHT11, DHT22 has higher precision and larger range. The temperature measurement range is from -40 to 80 degrees Celsius, with an accuracy of plus or minus 0.5 degrees Celsius; the humidity measurement range is 0-100 percent RH, with an accuracy of plus or minus 2 percent RH, which can provide users with more accurate temperature and humidity data. Digital Signal Output: A standard single bus interface is used to output a calibrated digital signal. Only one cable is needed to communicate with Arduino, simple connection, making system integration easy and fast, reducing the complexity of hardware design. Fast response speed: the sensor includes a capacitive moisture-sensing element and an NTC temperature measurement element, and is connected to a high-performance 8-bit microcontroller, with ultra-fast response capability, can quickly sense the changes in ambient temperature and humidity and output data in a timely manner. 2.Specifications Model No.: DHT22 Single Bus Digital Temperature and Humidity Sensor AM2302 Monitoring Sensor Module Product Dimensions: Length 37mm/1.45in, Width 15mm/0.59in, Height 7mm/0.27in, Operating Voltage 3-5.5v, Screw Fixing Hole Diameter 2.6mm/0.10in 3.Package Contains 1 x AM2302 Temperature and Humidity Sensor with Cable 4.Tips If used in outdoor or humid environment, you need to add a waterproof case for the sensor (only the sensing surface is exposed) to prevent rain and water vapor from directly contacting the components.
