2. Product Features
- High-precision digital display for temperature and humidity.
- Dual output for automatic constant temperature and humidity control.
- Utilizes an industrial-grade chip and high-precision SHT20 temperature and humidity sensor.
- Automatic Work Mode Identification: The system automatically identifies heating/cooling and humidification/dehumidification modes based on set start/stop values.
- Remote Parameter Setting: Parameters such as start/stop temperature/humidity and correction values can be set via UART communication.
- Real-time Data Reporting: When enabled, the module reports temperature, humidity, and relay status via UART at 1-second intervals.
- Temperature Correction Function (OFE): Allows adjustment of measured temperature from -10.0℃ to 10℃ to compensate for sensor bias.
3. Setup and Wiring
Careful wiring is essential for proper operation. Refer to the diagrams below for connection details.
Figure 2: Component layout and basic connections. This diagram shows the DC 6.0-30V power supply input, temperature relay output, humidity relay output, MicroUSB 5.0V power port, 1M temperature and humidity sensor probe connection, and control buttons (TM+, TM-, RH+, RH-).
3.1 Power Supply Connection
- Connect a DC 6.0-30V power supply to the V+ and V- terminals. Ensure correct polarity.
- Alternatively, the module can be powered via the MicroUSB 5.0V port.
3.2 Sensor Connection
- Connect the 1M temperature and humidity sensor probe to the designated header on the module.
3.3 Equipment Wiring
The module provides two relay outputs for controlling external heating/cooling and humidification/dehumidification equipment.
Figure 3: Wiring diagram for connecting heating/cooling equipment and humidification/dehumidification equipment. Both can be powered by AC 110V or DC 0-30V, connected through the respective relay terminals.
- Connect heating/cooling equipment to the temperature relay output terminals.
- Connect humidification/dehumidification equipment to the humidity relay output terminals.
- Ensure that the power supply for the controlled equipment matches its requirements (AC 110V or DC 0-30V).
4. Operating Instructions
4.1 Display Overview
Figure 4: The module's display showing current temperature (H25.8°C) and humidity (E54.9%). The "OUT" indicator signifies that a relay is currently active.
The module's display shows the current temperature and humidity. When a relay is active, the "OUT" indicator will appear on the interface.
4.2 Setting Start/Stop Temperature
- Press the TM+ or TM- button to enter temperature setting mode.
- Use TM+ and TM- to adjust the desired start and stop temperatures.
- The system automatically determines the operating mode:
- If Start Temperature > Stop Temperature: Cooling Mode (C). The relay activates when temperature ≥ Start Temperature and deactivates when temperature ≤ Stop Temperature.
- If Start Temperature < Stop Temperature: Heating Mode (H). The relay activates when temperature ≤ Start Temperature and deactivates when temperature ≥ Start Temperature.
4.3 Setting Start/Stop Humidity
- Press the RH+ or RH- button to enter humidity setting mode.
- Use RH+ and RH- to adjust the desired start and stop humidities.
- The system automatically determines the operating mode:
- If Start Humidity > Stop Humidity: Dehumidification Mode (D). The relay activates when humidity ≥ Start Humidity and deactivates when humidity ≤ Stop Humidity.
- If Start Humidity < Stop Humidity: Humidification Mode (E). The relay activates when humidity ≤ Start Humidity and deactivates when humidity ≥ Stop Humidity.
4.4 Temperature/Humidity Correction (OFE)
To correct potential sensor bias:
- Access the correction setting (specific button combination or UART command, refer to advanced documentation if available).
- Adjust the correction value within the range of -10.0 to 10.0. The actual temperature/humidity will be (measured value + correction value).
4.5 UART Communication
The module supports UART communication for remote parameter setting and real-time data reporting. Refer to the technical specifications or advanced user guide for detailed UART protocol information.
5. Maintenance
- Keep the module clean and free from dust and moisture.
- Ensure proper ventilation around the module to prevent overheating.
- Regularly check wiring connections for security and integrity.
- Avoid exposing the module to extreme temperatures or corrosive environments.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module does not power on. | Incorrect power supply voltage or polarity; loose connection. | Verify power supply (DC 6.0-30V or MicroUSB 5.0V) and connections. Check polarity. |
| Relay not activating. | Set temperature/humidity not reached; relay disabled; wiring issue. | Check set start/stop values. Ensure relay enabling is active (default). Verify equipment wiring. |
| Inaccurate temperature/humidity readings. | Sensor not properly connected; sensor fault; environmental interference. | Check sensor connection. Apply temperature/humidity correction (OFE function). Ensure sensor is in a stable environment. |
| "OUT" indicator not appearing when expected. | Relay not activated; display fault. | Confirm operating conditions meet relay activation criteria. Check relay functionality. |
