Students from East China University of Science and Technology Developed Portable Environmental Monitoring Instrument

Methanal, carbon monoxide, such harmful gases will threaten people's health, and all monitoring instruments management are belongs to environmental monitoring bureau. Whether can design a type of portable monitoring equipment fitting for civilians? On the second Shanghai university students innovation forum, 5 undergraduate students from East China University of Science and Technology developed"Handheld environmental monitoring instrument" which gained the"My favorite item", and they are applying for patent, maybe it will be pushed to the market in the near future.


According to the introduction of student from machinery institute, during the process of environment contamination research, they realize the importance of environmental monitoring, so an idea appears in their mind that to design a kind of air monitoring instrument. Under the teacher's direction, using smart phone platform, a type of handy terminal which could collect the data of carbon dioxide,carbon monoxide and methanal, display and convey wirelessly.


The instrument size is almost like the smart phone, with fully touch electric screen, easy and convenient to operate, just as phone. There are three buttons marked as "methanal", "carbon monoxide","carbon dioxide", touch the button, it will display the concentration of the gas that existing in the air.


Every kind of the gas has set "alert value", if the concentration exceed the value, it will remind the users. So this kind of instrument let people know of the air quality at home, in office and in the public.


As we know, developed such small instrument, developer should master many fields of technical knowledge like singlechip,embedded system,GPRS module etc.. This kind of handy environmental monitoring instrument combines the GPRS function of mobile phone, make the instrument surf the internet like mobile phone, transferring the data to the long-range base station, then analysis and process the data.


Now, the students are applying the patent, they hope will push this product into the market, it offers more convenient,easier and reliable method for environmental monitoring. If doing some modify of the programme, it can monitor more environment quality such as soil, water, industrial pollution source and road traffic noise, and on the basement, may develop automatic detection and transmission, realize unmanned monitoring.
