E120 i-Monitor
Realtime Air Quality Monitoring for Your Neighbourhood
Air pollution is the cause of over 34% of deaths from stroke, lung cancer, and chronic respiratory disease. By knowing our surrounding air quality, we can take preventive steps to protect our family.

Jointly developed by i-Neighhbour and i-Radar, the i-Monitor E120 Series Air Quality Station, is specially designed to provide maximum accuracy and affordability. It is easy to deploy use for timely monitoring of air quality in any residential community. i-Monitor E120 Air Quality Station seamlessly integrated with i-Neighbour App, can measure major air pollutants such as PM2.5, PM10, CO, NO2, SO2 and O2. It provides real-time and accurate data for environmental monitoring and can perform continuous monitoring of a specific area under all weather conditions. The residential community and authority can now react more quickly and more precisely in situation of air pollution than they can by using other conventional methods.
