Air quality sensor – WT1
The WT1 is a versatile sensor that measures indoor and outdoor air quality.
It measures humidity, temperature, atmospheric pressure and, more specifically, fine particles (PM1, 2.5 and 10) and up to 8 different substances: 6 via electrochemical sensors(1) and 2 via optical sensors(2), depending on your needs.
These measurements are taken continuously and the data transmission interval can be configured (minutes, hours, etc.).
(1)The following electrochemical sensors are available: NO₂+O₃, NO₂, HCl (HBr), H₂O₂ (peroxide), CO, O₂, Cl₂, CH₂O formaldehyde, EtO, alcohols (ETO at +50 mV), PH₃, HCN, H2, RSH (mercaptan), NO, SO2, H2S, NH3.
(2) The following optical sensors are available: CO2, CH4 and VOC

The platform
This graph shows changes in atmospheric pressure levels
and solar radiation throughout the day.
Find alerts on the platform for threshold exceedances for all monitored elements (gas, particles, humidity, etc.).
FAQ
What is the position of the sensor when attaching it?
Sensors facing downwards.
Does the sensor comply with the GDPR?
The sensor, its software and algorithms are fully compliant with the GDPR.
Are administrative authorisations required to install the sensor?
Installation permits must be obtained for public structures and listed buildings. These are the responsibility of the customer.
They are not essential for private structures.
