Air Quality Sensors
Monitoring of environmental parameters and air quality
A Smart City shall first of all monitor the area through IOT devices detecting air quality, environmental parameters, traffic, noise pollution and vibrations.
By analysing the quality of the air and the environmental parameters it is possible to protect human health and the environment as a whole body: this is why the detection must take place over a widespread area as this provides a greater understanding of the phenomena of gas diffusion into the atmosphere: therefore it is necessary to put in place a number of sensors spread all over the area.
To achieve this, sensors have to be extremely small, cheap, high precision, tough and ideal for installation in urban areas on public lighting infrastructure.
There are several types of sensors for the detection of inorganic gases and volatile organic compounds which, observing the most strict EC directives, are carrying out the survey of parts per billion (ppb), listed below are the most requested:
- Carbon Oxide (CO)
- Nitrogen oxide (NO)
- Ozone (O3)
- Nitrogen dioxide (NO2)
On request, it is also possible to use optical monitors for the measurement of particulate matter such as PM10; PM2.5; PM1.
At the same time as air quality data, environmental parameters are also collected: temperature, humidity and atmospheric pressure.
