AM2301A Digital Temperature and Humidity Module is a temperature and humidity composite sensor with its calibrated digital signal output.It applies special digital module gathering technology and RH&T sensing technology,to ensure that the product has high reliability and excellent long-term stability.The product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability and high cost performance.Each sensor is calibrated in an extremely accurate humidity calibration laboratory.Calibration coefficients are stored in the form of program in the single chip computer. These calibration coefficients are called in the process of processing the detection signal inside the sensor. Standard single bus interface makes system integration easy and fast.Standard single bus interface makes system integration easy and fast. Ultra-small size, very low power consumption,Signal transmission distance can reach more than 20 meters, making it the best choice for all kinds of applications and even the most demanding applications. Products are cited as 1-Wire (single bus interface) connection is convenient.
