THE USE OF LOW-COST SENSORS IN INDUSTRIAL HVAC AND AIR QUALITY MEASUREMENT APPLICATIONS

The air quality applications and also the industrial ones require a series of strict characteristics when we talk about the precision and endurance of the hardware and software elements involved in the work processes. A series of big firms have asserted in time on this section of market, clutching the industrial parks in their technological facilities. But, as the technologies developed, it has emerged a series of advanced possibilities of professional manufacturing regarding electrical assembly and boxes for the packaging of the hardware devices. This allows small producers or even amateurs, to benefit from the advantages of PCB technologies, which can aid in the innovation and forthcoming of super-performant gadgets on the market. These can compete with similar products developed by the big firms previously mentioned. In the gadget category have come in sight a series of very precise sensors which can rise to the industrial quality level, and, in this case, a normal question arises: why not integrate these low-cost sensors in the industrial applications? For that purpose, I have suggested a comparative analysis between two sensors of air, useful in the HVAC (heating, ventilation and air conditioning) and air quality field, one of them being manufactured by a specialized producer and the other one a gadget manufactured by a small firm which has build-up its own device for measuring the speed of the air and integrated it in its own portfolio of clients with notable results. The sensor of the specialized producer is approximately nine times bigger than the gadget category, which is why it has turned to a profound comparative analysis.
