What It Does
Built for air quality & co₂.
3-in-1 LoRaWAN CO₂, temperature and humidity comfort sensor — for offices, classrooms and meeting rooms. LoRaWAN decoder: Nexelec carbon payload decoder & codec (The Things Network)
Highlights
Ten-year battery
Three integrated lithium cells give up to ten years of operation — deploy it in a classroom or office and it outlasts a typical facilities maintenance cycle without a revisit.
COFRAC-validated CO₂
Automatic weekly recalibration with COFRAC-accredited metrology validation means the CO₂ reading is reliable enough to cite in ventilation compliance records.
Five-minute reporting
Readings every five minutes over LoRaWAN give the resolution needed to correlate CO₂ spikes with occupancy patterns — useful for both ventilation optimisation and energy reduction.

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.
