ITEM NAME:DIY DHT22 Digital Temperature Humidity Sensor AM2302 Module+PCB w/Cable Product Description Description: DIY Electronic Kit DHT22 Digital Temperature Humidity Sensor AM2302 Module+PCB with Cable Feature: 1. AM2302 humidity sensitive capacitance digital temperature and humidity module is a temperature and humidity composite sensor with the output of calibrated digital signal. 2. It uses digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability of products. 3. The sensor consists of a capacitive humidity sensor and a high-precision temperature sensor connected to a high-performance 8-bit microcontroller. 4. Therefore, the product has the advantages of excellent quality, ultrafast response, strong anti-interference ability, and so on. 5. Each sensor is calibrated in the very humidity chamber. Calibration coefficients are stored in the form of a program in a single-chip microcomputer. 6. These calibration coefficients are called in the process of processing the detection signal inside the sensor. 7. The standard single bus interface makes integration easy and quick. 8. Ultra-small size, very low power consumption, signal transmission distance can reach more than 20 meters, making it a variety of applications and even for harsh applications of the best choice. 9. Ultra low energy consumption, long transmission distance, all automatic calibration, capacitive humidity sensor, complete interchangeability, standard digital single bus output, excellent long-term stability, high precision temperature measurement element. 10. Application scope: HVAC, dehumidifier, testing and testing equipment, consumer goods, cars, automatic control, data recorder, household appliances, humidity regulator, weather station, and other related humidity detect and control. Specification: Humidity measurement range: 0---100%RH Precision of humidity measurement: Â ±2%RH Temperature measurement range: -40.The standard single bus interface makes integration easy and quick. Included: 1 x Module. 1 x Connecting Cable. Due to the different display and different light, the picture may not show the actual color of the item.
