It uses digital module acquisition technology and temperature and humidity sensing technology to keep stable performance and high reliability. The sensor consists of a capacitive sensing part and a high precision NTC temperature measuring part connected to a high performance 8-bit microcontroller. Excellent quality, professional manufacturing, fast response and strong anti-interference ability. Each sensor is calibrated in an extremely accurate humidity calibration chamber with consistent performance. The calibration coefficients are stored in the microcontroller as a program, and these calibration coefficients are called internally during the processing of the detection signal. The standard single bus interface makes system integration quick and easy. Small size, low power consumption, signal transmission distance of up to 20 meters. The product is divided into 3 leads (single bus interface), and the 4-lead connection is convenient, and any bus mode can be freely selected.
