Description
The AM2301 digital temperature and humidity module is a temperature and humidity composite sensor with calibrated digital signal output.
It applies special digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability.
The sensor consists of a capacitive moisture sensing element and a high precision temperature measuring element, and is connected with a high performance 8-bit micro controller.
Therefore, this product has the advantages of excellent quality, super fast response, strong anti-interference ability and high cost performance.Each sensor is calibrated in an extremely accurate humidity laboratory.
The calibration coefficients are stored in the form of a program in a single chip microcomputer, and these calibration coefficients are invoked within the sensor during the processing of the detection signal.
Standard single bus interface makes system integration easy and fast.Ultra-small size, extremely low power consumption, the signal transmission distance can reach more than 20 meters, making it the best choice for various applications and even the most demanding applications.
The product is 3 leads (single bus interface) easy to connect.
Special packaging forms can be provided according to user requirements.
