NEMo Outdoor – Ambient air monitoring for industries and smart cities LVOC – TVOC – Temperature – Humidity – Pressure – NO2 – O3 – PM1-2.5-10 Air quality in cities is a major issue nowadays. Residents’ health condition can be easily affected by air pollution which causes allergies, respiratory tract infections and cardiovascular diseases. To address this challenge, cities are setting up a network of sensors to carry out simulation and pollution prediction models to better advice inhabitants.

Particulate matter: PM 1/2.5/10 Particulate matter is where most of the health-related costs come from that are linked to outdoor air quality. As they enter the body, they cause cardiovascular disease, brain disease and respiratory system infections. The come from various sources: diesel without a treatment system, fireplaces, industry, vehicle brakes and tire wear. How to measure Particulate matter (PM) ? The reference method involves a particle filter collecting pollutants and weighing thereafter. Sensor network uses a different method because such procedure is complicated to automate and democratize. PM sensors rely on laser that quantifies PM and then establishes a relationship with the mass to know the volume of PM. Benzene Benzene mainly comes from the use of hydrocarbons. It is highly reactive, and is one of the most dangerous pollutants even at low concentration. Nitrogen dioxide – NO2 Nitrogen dioxide comes from hydrocarbons combustion. It is mainly generated from road traffic. NO2 is irritating for the respiratory system.
