The quality of the air inhaled in Poland is not satisfactory - especially in winter - which is why air quality sensors are increasingly appearing on the market. The laser smog sensor is one of the products that will help monitor the amount of harmful particles in the air. In this article, we outline the specifics of such a device and hint at how it works.
Laser smog sensor - the most important parameters
The laser smog sensor is one of the outdoor air quality sensors, which uses built-in filters to determine the amount of harmful substances around us. Air quality monitors check for the presence of PM1, PM2.5 and PM10 particles. Some measure the presence of other substances, such as volatile organic compounds TVOC or formaldehyde. They also measure air temperature and humidity. If you are considering buying an air pollution sensor, go for one that measures the presence and amount of PM2.5 - this is the substance most commonly found in polluted air in Poland, and also the most harmful.
Technical specifications of laser smog detectors
The exact specifications of air purity sensors vary depending on the specific model or brand. However, most of them have fixed features built in, such as an LCD display that shows the current air quality status and determines the threat level. The Dienmern® model also has a fan, while the Kaiterra Laser Egg model is equipped with a mobile app to check data from GIOŚ air quality measurement stations across Poland. The app is also supported in Polish. The laser sensor is powered by a rechargeable battery, so the device is portable and does not need to be plugged in all the time. It can therefore be taken with you on a walk or to work. The rechargeable battery can be charged repeatedly via the microUSB port. Some of the models are also pre-programmed, so they do not require anything more than just starting up and using them. Each product also comes with an instruction manual.
How does the laser smog sensor work?
The air pollution meter described in this article works on the principle of a laser photometer. This means that such an external device draws in air using a built-in pump and then, using a laser sensor, the particles in the air and the amount of contamination are identified. The measurement result is immediately displayed on a monitor. However, it is not necessary to know the standards applicable to the amount of particulate concentration in the air by heart, as the monitor will also display a colour indicating the air quality. The colour range is fairly standard: green indicates good quality, orange indicates medium quality and red indicates well below standard. If you live in an area with frequent smog and want to check what harmful substances are in the air you are inhaling, investing in a laser smog sensor might be a good idea. This device will enable you to continuously monitor the air quality anywhere.
