How the XH-M452 Works
The XH-M452 uses a high-precision temperature and humidity sensor to monitor environmental conditions. When the detected values exceed the user-set limits, the device activates or deactivates connected heating, cooling, humidifying, or dehumidifying equipment via its relay outputs.
Working Principle
- Sensor Detection
- The external probe measures real-time temperature and humidity.
- Data Processing
- The internal microcontroller compares the readings with the set threshold.
- Relay Activation
- If values exceed limits, the corresponding relay turns ON or OFF to activate a heater, fan, humidifier, or dehumidifier.
- Real-Time Adjustment
- The device continuously adjusts to maintain stable conditions.
