GETTING STARTED

1. Slide [CHANNEL] to set the channel number for your sensor(s).
2. Use a pin to press [RESET] key for run the channel number.

Note:
– If there are more than one sensor in use, ensure to assign different channel numbers for each sensor to enable the measurement to displayed correctly on the console (purchase of separately).

DISPLAY MODE
Press [MODE] to toggle the display mode between PM10 and PM2.5.

MEASUREMENT INTERVAL

Powered by DC adapter
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 battery 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 flashing
2. Press [MODE] to choose which interval time.
3. The setting sequence: 10m ‣ 20m ‣ 30m
4. Press [CHECK] to finish the setting and go back to normal display.

value every 1 minute
20| The sensor will detect the PM value every 10 minutes
30| The sensor will detect the PM value every 20 minutes
| 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*:

Good ↔ Hazardous

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
36-53| 51-75| Continue with normal activities| Continue with normal activities| Continue with normal activities
54-70| 76-100| Reduce prolonged or strenuous outdoor physical exertion| Minimize prolonged or strenuous outdoor physical exertion| Minimize prolonged or strenuous outdoor physical exertion
71-150| 101-350| Avoid prolonged or strenuous outdoor physical exertion| Minimize outdoor activity| Avoid outdoor activity
151-250| 351-420| Minimize outdoor activity| Avoid outdoor activity| Avoid outdoor activity
251+| 420+| Avoid outdoor activity| Avoid outdoor activity| Avoid outdoor activity

• 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.

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.

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 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) 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 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 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. Hand the sensor on to the screw with or without the mounting adaptor.

Note:
– Higher sitting may also be appropriate if the sensor is representative of a large area.
