AiroCheck wireless duct air quality sensor by MachineSens IoT

The AiroCheck duct sensor is a wireless, battery-powered air quality sensor that mounts on a duct or AHU. It measures temperature, humidity and CO2 in the supply or return air and sends readings over LoRaWAN EU868 to a MachineSens gateway. Data flows into BuildOT One for dashboards, alerts and BMS integration.

Measures air and thermal comfort with a single sensor.

AiroCheck Eco Monitor is a customizable and compact wireless indoor air quality sensor designed to measure and monitor various parameters in the air to assess the quality of the air we breathe.

These sensors are valuable tools for detecting and quantifying environmental conditions, pollutants, and particulate matter, providing near real-time or periodic data on air quality conditions.

The Eco Monitor 3 in 1 Duct sensor delivers and transmits highly accurate data wirelessly through low-power long-range communication. The sensor data and dashboards help monitor and report air quality performance.

The sensors within Eco Monitor can also be customized and configured to parameters to measure Dust, PM1, PM2.5, PM 10, Formaldehyde (HCHO), Carbon Dioxide (CO₂), Temperature, Humidity, Atmospheric Pressure, TVOC, Ozone (O₃), Oxygen (O₂), Hydrogen Sulfide (H₂S), Methane (CH₄), Carbon Monoxide (CO), Nitrogen Dioxide (NO₂), Sulphur Dioxide (SO₂), Hydrogen Gas (H₂), Ammonia (NH₃) and THI for swift assessment of environmental conditions that may affect microbial activity such as bacteria and fungi.

AiroCheck Air Quality Duct Sensor

Communication Technology

The AiroCheck Eco Monitor air quality sensors employs cutting-edge communication technology, LoRaWAN which provides low power consumption as well as long range signal propagation to enable real-time control and monitoring.

Our smart gateway receives near real-time data from all the wireless sensors within range, converts the raw data into an easy-to-use JSON format, and then publishes it using MQTT protocol. Data can be sent to any local or cloud MQTT broker via Ethernet, LTE (4G), or WIFI.
