What It Does
Built for air quality & co₂.
Indoor air quality monitor — CO₂, VOC, temperature, humidity, light, noise and motion in one device. LoRaWAN decoder: Nexelec AERO CO2 3-in-1 Smart sensor payload decoder & codec (The Things Network)
Highlights
COFRAC-validated CO₂
Automatic weekly recalibration backed by COFRAC-accredited metrology means the reading is audit-ready — not just a number on a screen.
Seven measures, one device
CO₂, VOC, temperature, humidity, light, noise and motion from a single wall-mounted unit — fewer devices to install, fewer batteries to manage.
USB-C powered
Plugs into a standard USB-C adapter, so there are no batteries to replace and no scheduled maintenance visits just to keep it running.

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.
