The AM2301 Humidity Capacitance Digital Temperature and Humidity Sensor is a temperature and humidity composite sensor with a calibrated digital signal output.
It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability.
Therefore, the product has the advantages of excellent quality, fast response, strong anti-interference ability and high cost performance.
Each sensor is calibrated in a precision 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.
The sensor consists of a capacitive sensing element and an NTC temperature measuring element connected to a high performance 8-bit microcontroller.
Communication with the microprocessor via a single bus requires only one line, 40 bits of data at a time, high first out. Small size, low power consumption, long communication distance, can be used in demanding applications.
