PM2.5/PM10 CONCENTRATION
For easy visualization of air quality, the device spreads the concentration readings over 6 level
scale.
The following provides some gives health guidelines on activities between good and hazardous
air quality*:

*Always consult/check with your doctors for any medical advices concerning the air quality and
your health.
Note:
This 6 level scale of PM2.5 / PM10 concentration is not the same as Air Quality Index (AQI).
BATTERY POWER STATUS
The device is powered by rechargeable batteries, and comes with battery power indicator. The
battery life of the device from fully charged batteries is determined by the number of detections
it performed, either through set intervals or manually activated by user.
100%
80%
60%
40%
20%
< 20%
When battery power fails to below 20%, user should recharge the batteries by connecting to a
USB port using the cable provided.
Note:
When the wireless PM2.5/PM10 air quality sensor’s battery power is below 20%, its detection
function will temporary suspension.
CHARGING BATTERY
You can use the micro USB cable to charge the wireless PM2.5/PM10 sensor if the battery
states show in “Low battery”. When Micro USB port plug in the micro USB cable for charging,
the LCD will display
and flashing battery icon.
: Charging underway
: Charged to full capacity
Note:
- Charged to full capacity from <20% battery power status require 24 hours.
REPLACE THE RECHARGEABLE BATTERIES
Over time, the batteries may degrade in terms of holding the highest capacity for which it was
designed for. If you find the device’s battery power is not lasting as it used to be, it’s probably a
good time to change them.
1. Unscrew and remove the
battery door of sensor with
a screwdriver.
2. Pull the black ribbon lying
under the batteries. All
batteries can be removed
together.
3.
Insert new 3 x AA size rechargeable batteries into the battery compartment according
to the polarity mark inside battery compartment.
4. Screw the battery door compartment on tightly.
5. After inserting batteries, all LCD segment will be shown for 1 second.
Note:
Please prepare a screwdriver for removing and close the battery door.
PAIRING WIRELESS SENSORS TO CONSOLE DISPLAY
This Wireless PM2.5/PM10 Air Quality Sensor can connect to the Air Quality Display console.
1. After power up the wireless air quality sensor, it will automatically enter registration
mode for 10 minutes until which it can be paired by the display console.
2. Once the connection is successful, the signal strength indication
and PM2.5/
PM10 information will appear on the display console.
Note:
- If you need to re-assign the sensor channel, slide the channel slide switch to the new
channel position, then use a pin to press
[ RESET ]
key to restart the sensor.
- To avoid the sensor(s) and console pairing failure during new channel number
assigned and setup, please power up the sensor(s) first, and then press
[ SENSOR ]
key on the main unit.
- After connected to the console display, the reading will transmit every 12 seconds in
the first 5 minutes. Every reading transmission, the symbol of signal transmission
,
will flash 0.5 seconds at once.
VIEW DATA ON CONSOLE
You can view the readings of your PM2.5/PM10 sensor(s) on the console receiver to which the
sensor(s) is linked to. Readings can then be analyzed into averages of past 24 hours or
maximums of past 1 hour, 24 hours, or since its last reset.
DATA TRANSMISSION
The device transmits its updated reading at fixed interval of 60 seconds to the paired console
receiver.
RESET THE SENSOR
In case of malfunction, use a pin to press
[ RESET ]
button to reset the sensor.
SENSOR INSTALLATION
The sensor is designed for desktop or wall mount for easy viewing. Follow the guidelines below
for the sensor placement.
1. Choose an open area away from any emissions source of pollutants, heat source, or
with air flow greater than 1m/s.
2.
Place the wireless PM2.5/PM10 sensor at least 1.5m to 2m above the ground to
better illustrate the detection of air quality in the human breathing zone.
3.
Do not expose the sensor to direct sunlight.
Wall mounting
Sensor can be mounted on the wall at different angle, either at
slant angle or vertically with the mounting adapter (included).
Place a screw on the wall where you wish to hang for sensor. Hang the sensor on to the
screw with or without the mounting adaptor.
Vertical angle
Slant angle
Note:
- Higher siting may also be appropriate if the sensor is representative of a large area.
