connected.
- Consult the dealer or an experienced radio/TV technician for help.
“ FCC RF Radiation Exposure Statement
Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the unit at least
20cm from nearby persons.”
Thank you for purchasing the Wireless PM2.5/PM10 Air Quality Sensor. Please read the instructions
carefully according to the version you purchased and keep the manual well for future reference.
IMPORTANT NOTE
- Read and keep these instructions.
- Do not cover the ventilation holes with any items such as newspapers, curtains etc.
- Do not clean the unit with abrasive or corrosive materials.
- Do not tamper with the unit’s internal components. This invalidates the warranty.

- Do not dispose old batteries as unsorted municipal waste. Collection of such waste separately
for special treatment is necessary.
- Attention! Please dispose of used unit or batteries in an ecologically safe manner.
-
Technical specifications and user manual contents for this product are subject to change without
notice.
-
CAUTION: Risk of explosion if the battery is replaced by an incorrect type.
-
High or low extreme temperatures that a battery cannot be subjected to during use, storage or
transportation and low air pressure at high altitude.
- Replacement of a battery with an incorrect type that can defeat a safeguard.
-
Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, that
can result in an explosion.
-
Leaving battery in an extremely high temperature surrounding environment that can result in an
explosion or the leakage of flammable liquid or gas.
-
A battery subjected to extremely low air pressure that may result in an explosion or the leakage
of flammable liquid or gas.

- This device is only suitable for mounting at height < 2m.
INTRODUCTION
Why PM2.5?
PM2.5 (particles less than 2.5 micrometers in diameter) can penetrate deeply into the lungs,
irritate and corrode the alveolar wall, and consequently impair lungs function, thus triggering
asthma attack or contributing to cardiovascular disease. Example of PM2.5 are fine dust from
vehicle exhaust, wildfire, power plant emissions, other combustion activities.
Why PM10?
PM10 (particles less than 10 micrometers in diameter) can irritate exposed mucous such as the
eyes and throat. Thus high levels of PM10 could easily make people cough, nose run and eyes
sting. PM10 includes dust from construction sites, highways, roadways, landfills and agriculture,
wind fires and bush/waste burning, industrial source; wind-blown dust from open lands, pollen,
mold spores, and fragments of bacteria.
Swiss sensor technology with MCERTS certification
The device comes with Swiss made SENSIRION Particulate Matter Sensor SPS series
designed for indoor and outdoor air quality application. Its measurement principle is based on
laser scattering and innovative contamination-resistance technology, which enables precise
measurements from the device’s first operation and throughout its lifetime of usage.
Multi-zone feature
Through our multi-zone technologies, each device has a unique device code with a user
selectable channel number. Up to 4 separate air quality sensors can be placed in an open
proximity covering an area across 100m radius from its main display unit (to be purchased
separately).
Low maintenance
The Swiss sensor is expected to have a lifetime of over 10 years while operating continuously
for 24 hours/day. With its contamination-resistance material, there is no need for cleaning and/or
maintenance, thus avoiding problems related to sensor drift or malfunction.

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.
