Active + developingEnvironmental infrastructure
Sensors, connectivity and installation that bring local environmental measurements online — from partner devices to our own node.
Overview
From field hardware to data
Today the network runs on proven partner sensors. In parallel we are building our own outdoor node, so cities can scale to dozens of locations at lower cost.

Our own sensor
SmartFlow Node:
SEN66 + NB-IoT.
Designed in-house for large city networks: professional sensing, low-power cellular connectivity and solar operation.
- Sensirion SEN66 — PM1, PM2.5, PM4, PM10, temperature, humidity, VOC, NOx and CO₂ in one module
- NB-IoT connectivity — works without Wi-Fi, low data cost
- Solar-ready power design for poles without electricity
- Same platform — appears on the map and panel like every other sensor
Status: in development and field testing. Not yet part of the live network.

In the field today
Partner hardware, installed with the city
02
Orient
Direction is recorded on site so wind and pollution sources can be interpreted later.
03
Mount
Sensors are mounted on existing street-light poles or buildings, together with the municipality.
