Environment monitoring device

Abstract

An environment monitoring device comprises a hardware part and a software part. The hardware part comprises a power supply, a sensor, an interface circuit, a single-chip microcomputer and a display module. The power supply supplies power to the sensor and the single-chip microcomputer. The sensor is connected with the single-chip microcomputer through the interface circuit. The single-chip microcomputer is externally connected with a keyboard and the display module. The sensor transmits the received data to the single-chip microcomputer. The single-chip microcomputer performs testing determining and displays information through the display module. According to a portable environment monitoring environment which is powered based on solar energy, an AT89C52 single-chip microcomputer is usedas a core processor; a three-in-one sensor acquires values of corresponding physical quantities; testing and displaying are controlled by the AT89C52 single-chip microcomputer, thereby simplifying system configuration and reducing designing and production cost. The environment monitoring device further has advantages of convenient operation, simple structure, high safety, high reliability, solar power supplying, low cost, convenient manufacture, automatic recording, storage function, high practicability, etc. The environment monitoring device supplies a condition for scientific development ofa household environment and is suitable for purchasing by domestic consumers.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an environmental monitoring device. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, at the same time, more and more pollution sources such as industrial waste gas, household waste gas, automobile exhaust gas and gas emitted from home decoration materials are brought, which have a bad impact on the living environment of human beings. For example, toxic and harmful gases such as PM2.5 and PM10 in the atmosphere, and formaldehyde gas emitted by interior decoration materials are always threatening people's health. At the same time, factors such as indoor environment temperature and humidity also affect people's daily life. In order to make people live in a healthy and comfortable environment, it is necessary to be able to monitor parameters such as toxic and harmful gases, temperature and humidity in the...

AI Technical Summary

Problems solved by technology

People are increasingly in urgent need of an easy-to-use, high-quality, low-cost, cost-effective, multi-functional, portable environmental monitoring instrument; Monitoring instruments not only have many varieties, but also have a large output, such as formaldehyde measuring instruments, PM2.5, PM10, temperature and humidity measuring instruments, etc., have formed a certain technical capability and production scale. However, due to the late start of the development of environmental monitoring instruments in my country, funds Insufficient investment, there is still a big gap compared with international developed countries in this respect, specifically manifested in single function, high cost, high failure rate, far from people's actual expectations
