- Mounting Hole: For wall mounting the sensor.
- RF Signal LED: Flashes once every 30 seconds to indicate signal transmission.
- TX Button: Transmits RF signal manually.
- Remote Channel Switch (1/2/3): Allows selection of one of three available channels.
- Battery Compartment: Holds 2 x AA batteries.
5. Setup
5.1 Battery Installation
- Open the battery compartment cover on the back of the sensor (refer to Image 2).
- Insert 2 x AA batteries, ensuring correct polarity (+ and -).
- Close the battery compartment cover securely.
5.2 Channel Selection
The sensor supports 3 channels. If you are using multiple sensors with one main unit, assign a different channel to each sensor.
- Locate the Remote Channel Switch inside the battery compartment (refer to Image 2).
- Slide the switch to select Channel 1, 2, or 3.
- Ensure the selected channel matches the channel setting on your compatible main unit (WS002/WS003).
5.3 Pairing with Main Unit
After installing batteries and selecting a channel, the sensor will automatically attempt to pair with your main unit. If pairing does not occur automatically, or if you need to re-pair:
- Ensure your main unit (WS002/WS003) is powered on and within range.
- Press the 'TX' button on the sensor (refer to Image 2) to manually transmit a signal.
- Follow the pairing instructions for your specific main unit model (WS002/WS003) to establish a connection.
5.4 Placement
For optimal performance, consider the following:
- Place the sensor in a location that provides accurate readings, away from direct sunlight or heat sources.
- Ensure the sensor is within the transmission range of up to 330ft (100m) in open air from the main unit. Walls and obstacles may reduce this range.
- Utilize the mounting hole for wall installation or place it on a flat surface.
6. Operating
Once successfully paired, the sensor will continuously transmit temperature and humidity data to your main unit every 5 seconds. The main unit will display these readings.
6.1 Temperature Display
The main unit will display temperatures in either Celsius (°C) or Fahrenheit (°F). Refer to your main unit's manual for instructions on how to switch between these units.
7. Maintenance
- Cleaning: Wipe the sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries when the low battery indicator appears on your main unit. Ensure to use 2 new AA batteries.
- Storage: If storing the sensor for an extended period, remove the batteries to prevent leakage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No reading on main unit | Batteries are dead or incorrectly inserted. Sensor is out of range. Channel mismatch. | Check/replace batteries. Move sensor closer to main unit. Ensure sensor and main unit are on the same channel. Press TX button on sensor. |
| Inaccurate readings | Sensor exposed to direct sunlight, heat source, or moisture. | Relocate sensor to a shaded, well-ventilated area. Ensure it is protected from heavy rain. |
| Weak signal | Obstacles (walls, electronics) between sensor and main unit. Distance too great. | Reduce obstacles or distance between units. Try different placement locations. |
