A small device that builds the big picture

Sensors can track all the key pollution markers like particulate matter (PM1, PM2.5, PM10), NO2, O3, SO2, H2S, NO, and CO gases. They also provide reliable data about key weather parameters such as temperature, humidity, air pressure, and wind from our sensors locations.

Measuring points

Measurement method

A single Airly device can measure two chemical compounds by the electrochemical method. Readings are taken from two gas cells installed in the measurement module of the sensor. Each sensor is equipped with a light diode that changes to present the current air quality using colour signals consistent with the CAQI or AQI scale.

Sensor Installation

Installation of the sensor is effortless. All it needs to work correctly is to be plugged into a regular power socket and hung on a height minimum of 1,5 m above the ground and not higher than 8 m. After 48h, calibrated measurements are visible on the Airly Data Platform, Airly Map and Airly Mobile App. Installation form
