Outdoor sensors install method:
In order to receive the true temperature, it is necessary to avoid installing sensors directly in the sunlight. We suggest installing the remote sensor on the wall facing north outdoors. Before installing the remote sensor on the wall, first screw a screw with a screw head set aside for 5 mm, and then install the outdoor sensor on the screw.
The electronic Part of the outdoor sensor has a layer of moisture-proof synthetic resin to protect the circuit.

Tips:
1. Do not install anti-battery positive and negative poles.
2. Sensor is not waterproof. Please avoid direct rain from wireless transmitters.
3. Product with hook!

Notes:
1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
2. Please allow 1-3mm measuring deviation due to manual measurement.
