4. Setup Guide
1. Remove the battery door on the base of the air
quality sensor.
2. Insert two rechargeable AA batteries.
3. After inserting the batteries, the remote sensor (red)
LED indicator will light for 4 seconds, and then
flash once per 10 minutes thereafter. Each time it
flashes, the sensor is transmitting data.
4. Close the battery door.
5. Connect the USB cable to a standard USB power
adapter (not supplied) and charge battery until blue
LED is turned off, indicating batteries are fully
charged.
6. Without the help of sufficient solar radiation, a fully
charged set battery can last for about 20 days(about
500hours), and battery status monitor on display
will reflect the battery power status. When battery
is empty, please charge sensor again to avoid a
complete battery discharge which is bad for
maintaining its charging performance.
7. When battery is empty, system will stop air quality
measurement, by then there will be no air quality
data measured but sensor sends out last measured
data all the time. If you see a not-changing PM2.5
value against low battery indicator, this means
sensor need to be charged immediately.
