Indoor air quality monitoring universal device

Abstract

Abstract This paper presents a solution for indoor air quality monitoring universal device. Existing devices on the market analyze a small number of indoor air quality parameters, require expensive consumables and periodic maintenance services. Our solution has a small volume, portable, easy to use, low price, almost non-existent maintenance, possibility monitoring a wide range of compounds and harmful elements of air. The proposed device can be equipped with a wide variety of sensors: gas sensor, digital gas sensor for air quality breakout, combined temperature and barometric pressure sensor, a 3 sensor device suitable for gas leak detection air quality monitoring. The results obtained with this device are: the individual values for each monitored element, local and online visualization of the data, the alarms for exceeding values, online access to data for analysis and processing. Finally, the solution proposed by us is cheap, we can work continuously, with the mention that if defects occur they can be remedied quickly by replacing the parts with replacement ones, without requiring periods of interruptions in the monitoring process.
