ASAIR AM2302/DHT22 Temperature and Humidity Sensor

1. Product overview 

AM2302 is a temperature and humidity composite sensor which is humidity Capacitive Digital Module and calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that products with high reliability and excellent long-term stability. The sensor includes a capacitive wet sensor and a high-precision NTC temperature sensor connected to a high-performance 8-bit microcontroller. Therefore, the product has excellent quality, fast response, anti-interference ability, cost-effective and so on. Each sensor is calibrated in a very accurate humidity calibration room. The calibration coefficients are stored in the form of a program in the microcontroller, and the calibration coefficients are called within the sensor during signal processing. Standard single bus interface makes system integration easy and quick. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it the best choice for all kinds of applications and even the most demanding applications. The product is divided into 3 leads (single bus interface), and 4 leads easy to connect, are free to choose any kind of bus. Special package can be provided according to user needs.
