Temperature/Humidity Sensor (AM2311A) Features an upgraded version of AM2311 Offers a stable temperature and humidity sensor module Has high reliability and excellent long-term stability Is ultra-small and has a very low power consumption The Temperature/Humidity Sensor (AM2311A) is a temperature and humidity composite sensor with its calibrated digital signal output. It applies special digital module acquisition technology and temperature and humidity sensing technology, to ensure that the product has high reliability and excellent long-term stability. 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. The standard single bus interface makes system integration easy and fast. It has an ultra-small size and very low power consumption. Its signal transmission distance can reach more than 20 meters.
