What It Does
Built for air quality & co₂.
An eight-in-one air quality sensor: CO₂, PM2.5, PM10, TVOC, barometric pressure, light, temperature and humidity, with an e-ink display. The full picture for wellbeing and certification standards. LoRaWAN decoder: Milesight AM308 payload decoder & codec (GitHub)
Highlights
Eight sensors, one device
Measures CO₂, PM2.5, PM10, TVOC, barometric pressure, light, temperature and humidity in a single wall-mounted unit — the complete picture for wellbeing and certification standards.
4.2-inch E-ink display
The large ultra-low-power E-Ink screen makes current readings visible in the room without any additional infrastructure — relevant for public-facing spaces like waiting rooms and classrooms.
PM2.5 and TVOC detection
Particulate and volatile organic compound monitoring helps identify ventilation problems and pollution sources that CO₂ alone would miss.

Complete The Setup
You will also need a gateway.
Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites.
On The Platform
A device on its own, or part of the bigger picture.
Buy this device and run it yourself, or have it monitored on the Planetic platform — live dashboards, standards tracking and automatic alerts, with the compliance evidence kept for you.
Questions
Good to know.
- Do I need anything else to use this device?
- Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites. The gateway itself does not need a sensor to run.
- Is the price ex VAT?
- Yes — all prices shown are ex VAT. VAT is added at checkout where applicable.
- Can I have it monitored on the Planetic platform?
- Yes. Buy the device outright and run it yourself, or have it monitored on Planetic — live dashboards, standards tracking and automatic alerts, with compliance evidence kept for you.
