What It Does
Built for air quality & co₂.
A three-in-one indoor air quality sensor — CO₂, temperature and humidity — with an e-ink display so the reading is visible in the room, not just on the dashboard. LoRaWAN decoder: Milesight AM103 payload decoder & codec (GitHub)
Highlights
E-ink display on wall
The 2.13-inch E-Ink screen shows the current CO₂, temperature and humidity reading in the room — staff see air quality at a glance without opening any dashboard.
NDIR CO₂ sensing
Non-dispersive infrared CO₂ measurement from 400 to 5,000 ppm gives an accurate ventilation proxy for classrooms, offices and meeting rooms.
Three-year battery life
Two replaceable ER14505 Li-SOCl₂ cells last approximately three years at a 10-minute reporting interval — no mains wiring needed and maintenance is minimal.

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.
