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 con
fi
guration 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.

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.
