Am2305 humidity capacitor module is a digital temperature and humidity that have been adjusted with digital signal output of the temperature and humidity integrated sensor. Its application-particular modules capture technology and advanced temperature and humidity sensor technology to guarantee item with high dependability and superb long-term security. Every sensor is an exceptionally accurate adjustment of humidity calibration chamber. Calibration coefficients put away in the microcontroller program, the sensor distinguishes the sign transforming inside the procedure to call these adjustment coefficients. Sensor comprises of a capacitive sense component and an accurate wet NTC temperature estimation gadgets, and with a superior 8-bit microcontroller associated. Subsequently, the item has an outstanding quality, quick reaction, hostile to obstruction capacity, high cost and so on.
