Hot selling spot AM2302 DHT22 temperature and humidity sensor module microcontroller red board

Product Descriptions

The AM2302 humidity sensitive capacitor digital temperature and humidity module is a temperature and humidity composite sensor with calibrated digital signal output. It applies dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has extremely high reliability and long-term stability. The sensor includes a capacitive humidity sensing element and a high-precision temperature measuring element, and is connected to a high-performance 8-bit microcontroller. Therefore, this product has the advantages of quality, ultra fast response, strong anti-interference ability, and extremely high cost-effectiveness. Each sensor is calibrated in an extremely humid calibration room. The calibration coefficients are stored in the form of programs in the microcontroller, and these calibration coefficients need to be called during the processing of detection signals inside the sensor. The standard single bus interface makes system integration simple and fast. Its ultra small size, extremely low power consumption, and signal transmission distance of over 20 meters make it an excellent choice for various applications, even for demanding ones. The product has a 3-lead (single bus interface) for easy connection. Special packaging forms can be provided according to user needs.
