AM2302 CAPACITIVE DIGITAL TEMPERATURE AND HUMIDITY SENSOR AM2302 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. Product parameters: Temperature range: -40~80°C Humidity range: 0~99.9%RH Temperature detection accuracy: ±0.5 °C Humidity detection accuracy: ±2% RH Resolution: 0.1 ° C; 0.1% RH Sampling period: 2s Output signal: digital signal single bus Supply voltage: DC3.3~5.5V
