Monitor air quality with sensors


To improve the monitoring network ofpollution atmospheric, gods can be used sensors able to collect data on air quality. The data, thus collected by sensor, they will then be sent to a device capable of analyzing them and drawing up a report. Similar monitoring tools are installed in different locations and as technologies advance, i sensors monitoring ofpollution have become increasingly accessible.

There are several on the market sensors for monitoring thepollution. Some sensors they are specific for volatile organic compounds (VOC), others are selective to the hydrogen contained in the combustion gases or to other chemical agents such as solvent vapors and numerous polluting gases. More advanced sensors are able to detect traces of mercury, mercury is a pollutant 'emerging'Whose oxidized form is very harmful, as it is transferred into the food chain with greater ease than the elemental form.

All local administrations should install a sensor for monitoring thepollution but, due to frequent budget cuts, this is not always possible. The most virtuous citizens who want to monitor air quality with a pollution sensor completely personal, they can rely on some low-cost innovations. These are devices designed to transform your smartphone into an environmental monitoring center, we have seen it with the Sensordrome capable of recording levels of environmental humidity, carbon monoxide, fine dust, light intensity, pressure, VOCs and many other factors. An alternative to the Sensordrome is given by Kit Lapka, another sensor for thepollution designed for iPhone but with more advanced shapes: composed of 4 sensors and 4 peripherals covered in wood and white plastic that are connected to the iPhone through the headphone jack. The first sensor measures the temperature, the second the environmental humidity, the third the electromagnetic radiation. The fourth, the most interesting one, detects the concentration of nitrates present in the food, through a steel probe to be inserted into the food to be analyzed. It costs around 170 euros.
