Crowtail- DHT20

""Introduction""

DHT20 is an intelligent temperature and humidity sensor module, which is a new upgraded product of DHT11. The module is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element and a standard temperature sensor element. After comprehensive improvement, DHT20 reduces power consumption and costs while greatly improving its performance parameters in terms of measurement accuracy, power supply voltage, measurement range, response time, stability, etc. , far exceeding the reliability of the previous generation of sensors level. DHT20 has the characteristics of calibration-free, low power consumption, high precision, high stability, etc. It adopts a fully calibrated digital I2C interface, which has fast response, strong anti-interference ability and higher cost performance.
