Product description
Overview
The YO Pure Pro device measures indoor environmental conditions, including concentrations of
particulate matter (PM2.5, PM4, PM10), carbon monoxide (CO), carbon dioxide (CO2), and total
volatile organic compounds (TVOC). The included sensors also monitor atmospheric pressure,
illumination, temperature, humidity, and noise level. YO Pure Pro may be ordered with the default CO
sensor or customised to measure instead 03, ETOH, H2S, SO2, or NO2.

PM2.5, PM4 and PM10
The particulate matter (PM) sensor informs users about the quantity of particles in diameters equal
to or less than 2.5 μm, 4 μm, and 10 μm, respectively. Additional information about surrounding air
pollution may be obtained by analyzing these measurements.
Figure 5 Example of PM2.5 monitoring chart.
CO sensor
Monitoring the CO concentration value is considered a critical indoor environmental parameter
because of its odourless character and the potential for serious impact on human health when levels
exceed a threshold. Collected data is used to inform the proper amount of ventilation for an indoor
environment.
Figure 6 Example of CO monitoring chart.

YO Pure Pro User guide v1.3
page 12/42
CO2sensor
Monitoring the CO2level is an important indoor environment parameter that affects human health.
High levels within a short duration can cause, for example, poor concentration, loss of attention, and
an increased heart rate.
Figure 7 Example of CO2monitoring chart.
TVOC sensor
TVOC (total volatile organic compounds) is an important indicator of indoor hygiene and air quality.
This sensor measures the amount of compounds that can affect human health and comfort.
Figure 8 Example of TVOC monitoring chart.

Atmospheric Pressure
By tracking changes in atmospheric pressure it's possible to predict how the value/difference might
affect human mood.
Figure 9 Example of atmospheric pressure monitoring chart.
Illuminance
Illuminance sensor measures the value of light intensity. It can tell if there's a proper amount of light
in the room.

Temperature and relative humidity
Temperature and relative humidity are measured by sensors placed inside the device enclosure.
These measurements can be used to monitor ambient conditions (see recommended conditions).

SAFETY PRECAUTIONS
SYMBOL
DESCRIPTION
Device is marked with a symbol saying that electrical and electronic products
may not be mixed with unsorted household waste. Remember that batteries
used to power the device must be treated at a specialized treatment facility.
Remember about possible electrostatic discharge when replacing battery,
connecting input or doing some other operations near inside electronics.
Battery powered (Li-ion) as this may cause damage. The equipment should be
kept in a controlled environment. CAUTION: Batteries are at risk of exploding
if incorrectly replaced. Replace only with the same or equivalent type as
recommended by the manufacturer. Discard used batteries according to the
manufacturer’s instructions.
Be careful while handling the device – dropping it may cause damage that will
affect the sensors and other electronics inside.
When installing the device on the wall remember to wear adequate protective
equipment.
To maintain the level of protection device cover screws must be properly
tightened. Device shouldn’t be used without cover.
Any actions inside the device's enclosure (excluding replacing batteries) must
be performed by trained personnel only.
Clean the device only with damp cloth.

Device is intended for indoor use.
Installation guide
I. The device can be powered via a USB-C connector, an external power supply, or Li-Ion 18650
batteries.
1. USB-C connector 5 V DC. Plug the USB-C cable into the socket on the enclosure. If the
LED indicating the status of the device flashes blue, then the device is successfully
connected to the power supply.
Figure 14 Connecting USB-C cable to the device.
2. Power supply 6-30 V DC or 5-21 V AC. Remove the protective cap located at the bottom
of the enclosure to access the socket. Screw the external power supply wires into the plug of
the connector. Next, insert the connector into the socket located at the bottom of the
device. If the device status LED flashes blue, then the device is successfully connected to
the power supply.

Figure 15 Connecting the power supply to the device.
3. Backup batteries Li-Ion 18650. Remove the three screws located on the bottom of the
device’s enclosure (3 out of 6 places marked with +) to remove the top of the enclosure.
Remove the battery lock and insert two Li-Ion 18650 batteries.
IMPORTANT! Align the batteries with the correct +/- polarity before re-inserting the
battery lock. When the batteries are inserted correctly, the charging process begins, and the
battery charging LED illuminates orange.
Figure 16 Inserting two batteries into the device.
II. There are 3 ways to install the device:

YO Pure Pro User guide v1.3
page 19/42
1. Place on a desk. Install the rubber feet (installed by default) and connect the power supply.
Figure 17 Installation of the rubber feet for a desk placement.
1. Mount on a wall.
A. Screw the mounting nuts into the enclosure (see Figure 18).
Figure 18 Screw the mounting nuts into the device for a wall installation.
B. Install the mounting bracket on the wall using screws (see Figure 19). Screw the
bracket to the wall using your preferred mounting holes.

C. When using a 6-30 V DC or 5-21 V AC power supply, the centre plastic circle labelled
PUSH must be snapped out of the mounting bracket before installation. Next, route
the cable through the centre hole of the bracket.
Figure 19 Install the wall-mount bracket onto the device.
D. Attach the device to the mounting bracket by first fitting the mounting nuts on the
device into the mounting holes of the bracket. Next, turn the device clockwise (see
Figure 20) until aligned to its final orientation (see Figure 21).
Figure 20 Turn the device clockwise after inserting into the bracket for mounting on a wall.
