AM2105A digital temperature and humidity sensor is a temperature and humidity composite sensor with calibrated digital signal output. Adopting specialized temperature and humidity collection technology ensures that the product has extremely high reliability and excellent long-term stability. The sensor includes a capacitive humidity sensing element and a high-precision integrated temperature measuring element, and is connected to a high-performance microprocessor. This product has the advantages of excellent quality, ultra fast response, strong anti-interference ability, and extremely high cost-effectiveness. The AM2105A communication method adopts a single bus communication method with a standard single bus interface, making 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. By directly outputting digital information such as humidity, temperature, and calibration after temperature compensation, users can obtain accurate temperature and humidity information without the need for secondary calculation of the digital output or temperature compensation of humidity. The product has 3 leads, easy to connect, and special packaging forms can be provided according to user needs.
