How to Install Outdoor Sensors:
1. In order to receive the true temperature value, it should be avoided to install the sensor directly in the sun. We suggest that the remote sensor should be installed on the wall facing north.
2. Before installing on the wall, we should first set a screw with the screw head of 5mm, and then install the outdoor sensor on the screw.
3. The electronic part of outdoor sensor has a layer of moisture-proof synthetic resin to protect the circuit. But the sensor is not waterproof, so direct rain should be avoided.
4. Hook is included.
Do not install the negative and positive poles of the battery.
Avoid direct rain from the wireless transmitter.
Please allow 1-3mm differs due to manual measurement.
