Students from East China University of technology developed hand-held environmental monitoring instruments

at the second Shanghai University Students' Innovation Forum held a few days ago, the "hand-held environmental monitoring instruments" developed by five undergraduate students from East China University of technology won the title of "my favorite project" and is applying for a patent, hoping to be introduced to the market in the future

formaldehyde, carbon monoxide and other harmful gases pose a threat to people's health, and the instruments monitoring them are only owned by the environmental monitoring department. Can we design a portable and simple environmental monitoring instrument suitable for ordinary people? At the second Shanghai University Students' Innovation Forum held a few days ago, the "hand-held environmental monitoring instrument" developed by five undergraduate students of East China University of technology won the title of "my favorite project" and is applying for a patent, hoping to promote enterprises to accelerate technological progress to the market in the future

according to Xiang Sitong from East China Institute of technology and machinery, he and his classmates realized the importance of environmental monitoring in the process of studying environmental pollution and came up with the idea of designing a household air quality monitor. Under the guidance of teachers, they used the intelligent platform to develop a handheld terminal, which can collect, display and transmit data of carbon dioxide, carbon monoxide, formaldehyde and other gases wirelessly

this instrument is about the size of an intelligent one. It has a full touch electronic screen, which can be operated as easily as using a touch screen. The interface is marked with "formaldehyde", "carbon monoxide" and "carbon dioxide". Press it once to display the concentration of the gas in the current environment. If the concentration of carbon monoxide is displayed as "10ppm", it means that the content of carbon monoxide in the air is 10 parts per million

Xiang Sitong said that they set "early warning values" for each gas, and as long as it exceeds a specific concentration, it will timely remind users. This portable instrument can let people know the air quality in homes, office buildings and places they go

6. According to the use frequency of the equipment, to develop this small instrument, we need to master the scientific and technological knowledge of SCM, raw material preparation (mining or transportation), product production and use of embedded systems, GPRS modules and other fields. Xiang Sitong said that in the process of research and development, they encountered problems such as not knowing what kind of sensor to choose and reporting errors in the process of program compilation, but they digested relevant knowledge and skills one by one by consulting books and consulting instructors, and finally achieved results. This hand-held environmental monitoring instrument combines the GPRS function used by people in daily life, so that the instrument can wirelessly transmit the collected data to the remote base station as above, and further analyze and process the data, reflecting the characteristics of wireless connection of intelligent devices

now, Xiaoxiang is applying for a patent, hoping to bring it to the market in the future, providing a more convenient, easy and reliable method for environmental monitoring, so that residents can monitor whether there are harmful gases in the house at home, and office workers can use it to monitor the air quality in the Office. Xiao Xiang said that this handheld environmental monitoring instrument can not only monitor environmental gases, but also monitor more environmental quality, such as soil, water quality, industrial pollution sources, road traffic noise sensors whose output signals are absolute numerical sound, if the program is simply modified. On this basis, automatic detection and transmission functions are developed to realize unmanned monitoring
