På webwebsted, kan du view detailed PM2.5 and AQI data graphs and download historical records for long-term analysis. It is recommended to add a shortcut to the website on your phone's home screen for quick access.
5. Vedligeholdelse
5.1. Batteriopladning
The included Ni-MH batteries are rechargeable. It is recommended to charge the batteries using the provided USB cable approximately every two weeks to ensure continuous operation, especially if the solar panel receives insufficient sunlight.
5.2. Rensning
Periodically clean the exterior of the sensor unit with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the device. Ensure the solar panel is free of dust and debris for optimal charging efficiency.
6. Fejlfinding
- Sensor Not Displaying Data: Ensure the WH41 sensor has fresh or fully charged batteries and is within range of the GW1100 Wi-Fi gateway. Verify the GW1100 gateway is properly connected to your Wi-Fi network.
- "Accessory Only" Message: The WH41 is an accessory sensor and cannot operate independently. It requires an ECOWITT GW1100 Wi-Fi gateway (or a compatible display console, sold separately) to function and display data.
- Multiple Sensors Not Showing: Confirm your GW1100 firmware is updated to V1.4.6 or higher via the WS View Plus App. Ensure each sensor is powered on sequentially to be recognized as a distinct channel.
