Section digital temperature and humidity sensor is a digital signal containing a calibrated temperature and humidity sensor signal output of the complex . It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. Electrical sensor comprises a capacitance -type sensing the wet element, and a high-precision temperature measuring devices, and with a phase high-performance 8-bit microcontroller is connected. Therefore, 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 chamber. The calibration coefficients are stored in the OTP memory as a program, and these calibration coefficients are called internally during the processing of the detection signal. Single- wire serial interface, system integration becomes simpler and quicker. Ultra-small size, extremely low power consumption, and signal transmission distances of up to 20 meters make it the best choice for even the most demanding applications.
