SHT20 Temperature and Humidity Controlled 2 Channel Independent Relay Module XH-M452
XH-M452 is a temperature and humidity controlled relay card. It has two relays independent of each other. One of these relays works according to the temperature value and the other works according to the humidity value. It can be used in incubators, smart home projects, heating and cooling systems.
XH-M452 Technical Specifications:
- Input voltage: DC 12V
- Temperature range: -20 ~ 60
- Humidity range: 00% - 100% RH
- Detection accuracy 0.1, 0.1% RH
- Sensor: 1 Meter Temperature and humidity sensor SHT20
- Output Type Relay Output (Switch Output)
- Dimension 65 * 55 * 28mm
Usage:
- The product is supplied with 12V DC from the two terminals in the middle.
- The red screen shows the temperature and the blue screen shows the humidity rate.
- The + button below the temperature screen. The key is pressed for a long time and the screen starts flashing, the upper temperature value is determined and after 3 seconds the screen stops flashing. When the same operation is performed with the - key, the lower temperature limit is determined.
- The same operations for temperature are repeated for humidity.
- To reset the parameters and reset the product, the - temperature key and the + humidity key are pressed simultaneously. should be kept.
