AM2302 Temperature and Humidity Sensor Introduction:

The AM2302 is a humidity capacitive digital module with a calibrated digital signal output that functions as a temperature and humidity composite sensor. To ensure that goods have a high degree of dependability and outstanding long-term stability, it uses specialized digital module acquisition technology as well as temperature and humidity sensing technology. The sensor has a high-performance 8-bit microprocessor linked to a capacitive moist sensor and an elevated NTC temperature sensor. As a result, the product is of great quality and has several advantages, including quick response, interference-resistance, and cost-effectiveness. In a humidity calibration room with extreme accuracy, every sensor is calibrated. When signal processing is taking place inside the sensor, the calibration coefficients are called from a programme that is stored in the microcontroller. The system integration process is made simple and rapid by the standard single bus interface.
