What It Does
Built for air quality & co₂.
Premium LoRaWAN indoor air quality monitor — adds formaldehyde and full PM1/2.5/10 to CO₂, VOC, temp and humidity.
Highlights
Formaldehyde and PM1/2.5/10
Measures formaldehyde and three particle-size bands that standard IAQ sensors miss — the evidence base for BREEAM Indoor Air Quality credits and Awaab's Law assessments.
COFRAC-validated accuracy
CO₂, temperature and humidity are validated against COFRAC-accredited metrology, so readings can be cited directly in compliance reports without further calibration.
USB-C, ten measures
All ten parameters from a mains USB-C unit — no battery changes, no scheduled swaps, and a single cable run rather than a cluster of specialist sensors.

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.
