4.3 Placement and Mounting
The sensor can be placed on a flat surface using its integrated stand or mounted on a wall using the hanging hole.
- For outdoor use, choose a shaded location to avoid direct sunlight, which can cause inaccurate temperature readings.
- Ensure the sensor is protected from direct rain and snow.
- Place the sensor within the wireless transmission range (up to 200-320 feet) of your weather station. Obstacles like thick walls or metal structures can reduce this range.
- Common placement areas include backyards, garages, greenhouses, gardens, kitchens, bedrooms, or offices.
