DHT22 / AM2302 Humidity Capacitive Digital Temperature and Humidity Module is a temperature and humidity composite sensor with a calibrated digital signal output. It uses a 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.
HVAC, dehumidifiers, testing and testing equipment, consumer products, automotive, automatic control, data loggers, home appliances, humidity regulators, medical, weather stations, and other related humidity detection control.
Ultra-low power consumption, long transmission distance, fully automatic calibration, capacitive humidity sensor, fully interchangeable, standard digital single bus output, excellent long-term stability, high-precision NTC.
