About the device

Connected Inventions AirWits PM is a wireless air quality metering device with

ultra long battery life. This intelligent and small device measures and sends the

particular matter mass concentrations PM1.0, PM 2.5 and PM10 as ug/m3 plus

temperature and humidity data sequentially from 10 min to 24 hours using the

world-wide Sigfox IoT-network connectivity for data transmission, enabling very

low lifetime cost. The installation of the device is extremely simple procedure

and requires neither special tools nor conﬁguration operation. The device is

maintenance free, and thus a great solution especially for long term indoor air

quality metering providing accurate data for energy savings and comfortable

living conditions which can be monitored remotely.

Functions

The basic functionality procedure example:

Diagram 1. Example of messages being sent and received

When the device is powered on, it will send the measurements and ask

downlink message from the network. If the downlink message is

conﬁgured and reconﬁgure bit is 1, new settings will be adopted. In case

downlink message is not conﬁgured, the reconﬁgure bit is 0 or the downlink

message cannot be read, the previous settings will remain. The transmission

interval time and adaptive power control function can be set through downlink

message. After the downlink request, the device sends only uplink messages for

next 24 hours. After every 24 hours, the device will send downlink request again

within next payload transmission.

Assembling and Installation

• Save the identiﬁer and the key of the device. The identiﬁer and the PAC key is

on the label on the bottom of the device. You can also read the identiﬁer and

the PAC key using the QR code.

Picture 1. Bottom label.

• Switch the device on sliding the power switch to position “1”

Picture 2. Slide the power switch to position “1”.

• Install the wall plate to the wall using screws suitable for the wall material.

Please note the orientation!

Picture 3. Install the wall plate with appropriate screws.

•Attach the device to the wall having the pins meeting installation holes in the

device. Please note the orientation!

Picture 4. Attach the device to the wall plate.

Please note! Avoid placing device closer than 15cm on any metal or

magnetic object, electric cables, electric devices or selective glass as

this will dramatically reduce radio performance as well as battery life of

the device.

Replacing batteries

• The device battery pack is proprietary made. Once device runs out of battery,

please contact your local partner or Connected Inventions for support the

battery pack replacement. Do not try to replace the battery pack with other

brands available as there is a risk of breaking the device. The battery pack lasts

years in normal use so in case of no messages received from the device,

please check ﬁrst the power is switched on and the Sigfox radio coverage is

available at the location.

Downlink

• Settings of the device can be updated with the downlink message

• Device requests new settings approximately every 24 hours

• You must be very careful when you update the settings

• settings aﬀect both the subscription and the battery life of the device!

• Downlink message is optional

• If any downlink message is not received, device continues with the current settings

• How often messages are sent can be adjusted with the settings

•Default settings when device has not been conﬁgured with downlink:

•Uplink reporting period is 30minutes

•#Adaptive Power Control is OFF

•#Full transmit power is used

•If the Adaptive power control feature is set on, the device will automatically adjust

the transmit power to optimum level to save battery and create less unnecessary

interference to radio network

•By default power control is OFF

•When power control is OFF, full TX power is used

•NOTE! The Adaptive power control feature only available in RCZ1 device
