An integrated device with built-in sensors for measuring air quality
– Nitrogen Dioxide sensor (NO2)
– Carbon Monoxide sensor (CO)
– Sulfur dioxide – Sulfur dioxide sensor (SO2)
– Temperature, atmospheric pressure and humidity sensors
– Particulate Sensor – PM2.5 and PM10 sensors
– Speed and direction of the wind (only in some devices)
– Also, the device will also have volume and volume sensors (ambient sounds) and UV radiation.
The device is controlled by a microprocessor with specially written embedded software.
Each device is equipped with GSM, WiFi and LoRaWan (alternatively or redundantly).
The first two functionalities are to enable networking devices in mesh – a network of nodes that communicate with each other and send data to a central server.
The GPS sensor and function will serve to accurately determine the position of the device at the street address level.
The device will be powered by solar energy (photovoltaic) and, alternatively, via a standard electrical connection.
All devices within a specified time interval (from a few minutes to a few hours) send the read data to a central server. The central server will accumulate data, and process it.
It is envisaged to set up hundreds of devices across the country to allow for good granulation and localization of data, as well as to compensate for any inaccuracies by using a larger amount of data from nearby locations.
The devices will be compact and weather-proof and thus could be put on a pole, a terrace, a roof, or any other similarly convenient place.
The processed data will be available on the website and on mobile applications. In addition, the data – in the form of big data – will be available for use through the API (the opportunity and other applications to use for scientific or public purposes).
The devices will be interconnected by using base stations which will be located in different key positions.
