LoRaWAN indoor air quality sensor with CO2 and E-Ink display EU868 Milesight AM307

The Milesight AM307 is designed for indoor spaces where air quality and room usage should be monitored continuously rather than checked occasionally. It measures several relevant environmental parameters in one device and also shows the readings directly on a 4.2-inch E-Ink display. This makes it especially useful in rooms where CO2, temperature, and humidity should be visible immediately without always needing to open a dashboard or app.

The EU868 version is especially relevant for schools, offices, meeting rooms, waiting areas, residential buildings, and other indoor spaces where air quality directly affects comfort, concentration, and energy use. CO2 readings help identify ventilation demand early. Temperature and humidity data support more stable indoor conditions. PIR occupancy detection and the light sensor add useful context about whether a room is in use and how it is being operated.

A practical advantage of the AM307 is the combination of sensing, display, and long battery life. The device can run on batteries or by USB Type-C power. This is especially helpful in retrofit projects where permanent power is not always available. At the same time, the data can be sent over LoRaWAN to systems such as Kilo or other compatible platforms for alarms, dashboards, and automation workflows.

The sensor measures CO2 by NDIR, along with TVOC, barometric pressure, temperature, humidity, light, and motion status. This makes it more than a simple CO2 monitor. It is a broader IAQ sensor for ongoing indoor environmental assessment. In schools or offices, it can support better ventilation and indoor comfort. In automated buildings, it can work with gateways, controllers, thermostats, or BAS systems so room conditions can be used directly in control logic.
