DHT22 AM2302 IIC I2C Single-Bus Digital Temperature and Humidity Sensor Module
Product Description:
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.
Applications:
HVAC, dehumidifiers, testing, and inspection equipment, consumer goods, automotive, automation, data loggers, weather stations, home appliances, humidity control, medical, and other relevant humidity measurement and control.
