DHT22- digital sensor for detecting the temperature and humidity in the environment. Unlike his predecessor DHT11, it has a high level of measuring accuracy and can be used on the street.
- The output of a digital composite signal from the temperature and humidity sensor has previously been calibrated.
- It's dedicated digital module acquisition technology and temperature and humidity sensing technology,
- Ensure that the product has very high reliability and excellent long-term stability.
- Includes capacitive moisture sensor component and high precision temperature measuring element,
- A high-performance 8 bitrate mini controller is connected.
- So the product has the excellent quality, ultra-fast response, strong anti-interference ability, extremely high price-performance ratio.
- Each sensor has a very accurate moisture calibration.
- Calibration factor in the form of a program stored in a microcontroller, and the sensor inside the detection process signal processing to call the calibration parameter.
- One standard bus interface, makes system integration becomes simple and fast.
- Super small size, low power consumption, the signal transmission distance of 20 meters,
- Products for 3 valves (one bus interface) convenient connection.
