7. Do’s & Don’ts

Low Temperature Environment Precautions (MUST-READ

for Built-in Battery Version).

Battery normal discharge temperature range: -20 °C to 60 °C

Battery normal charging temperature range:0 °C to 45 °C

Note that if the Sensor Hub you use has a built-in lithium battery, when powered by solar energy or a DC power

adapter:

1) If the ambient temperature is below zero, the battery will stop charging and resume charging only when the

temperature is higher than 0℃.

2) While it stops charging, if the battery is exhausted, the device cannot rely on the solar power or DC power to

work. You need to wait for the ambient temperature to be higher than zero and the lithium battery is charged to a

safe use level before the device can work.
