MEASUREMENT INTERVAL

The device measures PM2.5 or PM10 concentration every minute automatically when

powered with a DC adapter.

Manual detection

User can press [CHECK] button anytime to get an updated measurement of PM2.5 or PM10

concentration readings. (It takes approximate 10-12s to detect, the readings indicated by

blinking PM2.5/PM10 icon.)

Operated by batteries

When powered by batteries, it’s detecting every 10 minutes by default. To maximize the bat-

tery life, user can also change the detection interval from 10 minutes to 20 or 30 minutes.

Setting default mearurement interval

1. Press and hold [CHECK]for2secondsuntilthedisplayisashing

2. Press [MODE] to choose which interval time.

3. Thesettingsequence:10m‣20m‣30m

4. Press [CHECK]tonishthesettingandgobacktonormaldisplay.

Detection interval (Minute) Description

1 (when connected to adapter) The sensor will detect the PM value every 1 minute

10 (default) The sensor will detect the PM value every 10 minutes

20 The sensor will detect the PM value every 20 minutes

30 The sensor will detect the PM value every 30 minutes

PM2.5/PM10 CONCENTRATION

For easy visualization of air quality, the device spreads the concentration readings over 6 level scale.

The following provides some given health guidelines on activities between good and

hazardous air quality*:

PM2.5 PM10 Healthy persons Elderly, Children,

Pregnant Women Persons with chronic disea-

se or heart disease

0~35 0~35 Continue with normal activities Continue with normal activities Continue with normal activities

* 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ashing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nd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 bat-

teries. All batteries

can be removed

together.

3. Insert new 3 x AA size rechargeable batteries into the battery compart-

ment 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 powering 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

infromation will appear on the display console.

Note:

- If you need to re-assign the sensor channel, slide the channel slide switch to the new

cahnnel 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)rst,andthenpress[SENSOR]keyonthemain

unit.

- After connected to the console display, the reading will transmit every 12 seconds in the

rst5minutes.Everyreadingtransmission,thesymbolofsignaltransmission , will

ash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xed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owgreaterthan1m/s.

2. Place the wireless PM2.5/PM10 sensor at least 1.5m to 4m 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dierent

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. Hand the sensor on to the

screw with or without the mounting adaptor.
