The DHT22 Digital Temperature and Humidity Capacitive Humidity Detection Module is a module that contains a connection to calibrate the digital signal output of the temperature and humidity sensor. Achieves high reliability and excellent long-term stability by adopting dedicated digital module collection technology and temperature / humidity detection technology.
The
sensor incorporates a capacitive wet component sensor and a precision temperature measuring device and is connected to a powerful 8-bit microcontroller. This product has excellent quality, quick response, strong anti-interference capability, and high cost.
standard single bus interface, system integration is quick and easy. Its small size, low power consumption and signal transmission distance of up to 20 meters make it ideal for all types of applications and even the most demanding applications.
The
DHT22 is highly accurate and can replace the expensive import temperature and humidity sensor SHT10.
Can measure ambient temperature and humidity to meet high demands. This product is reliable and has good temperature and humidity perception.
Note: The digital temperature and humidity sensor DHT22 is designed for analog sensor interfaces. The analog port is used as a digital port and does not occupy the original Arduino digital port. Sensor leads that can convert analog functions to digital can be used with digital connections.
