The project will focus on developing a smart node built on environmental sensors that allow for measuring air pollution.
Air pollution is all substances in the form of gases, liquids or solids (dusts) that are not its natural components or occur in higher concentrations than natural.
In the past, the only source of pollution were natural processes, such as: volcanic eruptions, forest fires, atmospheric discharges and decomposition of organic substances. As a result, they produce: carbon monoxide, nitrogen oxides, methane, dust and volcanic gases, including carbon monoxide.
The development of motorization and industry has led to an increase in demand for energy generated from raw materials such as crude oil, natural gas and hard coal. During their combustion, carbon, sulfur and nitrogen oxides are created.
Air pollution has a negative impact on the natural environment. Their most dangerous effects are: acid precipitation, intensification of the greenhouse effect, ozone hole, smog, dust, soil and water pollution.
Pollutants whose main sources are car exhaust fumes, heavy industry and households (heating systems), combined with windless weather and high air humidity - fog, create smog. Smog floating over the city is particularly dangerous for infants, the elderly, asthmatics, people with respiratory and circulatory system diseases.
The device will consist of a control processor, a communication module sending data to the Internet via a cellular network or WiFi and a set of sensors.
The following systems can be used as the control processor: nRF7002 DK, nRF9151 DK, Photon 2, Arduino GIGA R1 WiFi.
The following will be used as sensors:
- Sensirion SEN50 PM sensor
- Sensirion SHT31 temperature and humidity sensor
- NXP MPL3115A2S barometric pressure sensor
- AMS AS7331 UV index sensor
- Rohm BH1721FVC ambient light sensor
- TDK ICS43432 noise sensor
