1、 Product Overview

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 excellent long-term stability. The sensor includes a capacitive humidity sensing element and a high-precision NTC temperature measuring element, and is connected to a high-performance 8-bit microcontroller. Therefore, this product has the advantages of excellent quality, ultra fast response, strong anti-interference ability, and extremely high cost-effectiveness. Each sensor is calibrated in an extremely precise humidity 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 the best choice for various applications, even the most demanding ones. The product is divided into 3-wire (single bus interface) and 4-wire connections, which are convenient and can freely choose any bus mode. Special packaging forms can be provided according to user needs.
