Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] The invention relates to a PM value detection device and method based on GSM wireless transmission. The PM2.5 detection device includes four parts: a PM2.5 detection module, a minimum system module of a single-chip microcomputer, a GSM communication module, and a mobile phone display terminal. The dust sensor in the PM2.5 detection module detects the concentration of PM2.5 in the air, and transmits the analog voltage corresponding to the concentration of PM2.5 in the air to the single-chip microcomputer. The single-chip microcomputer is connected to the GSM communication module through the serial port, and the GSM communication module communicates with the The display terminal of the mobile phone realizes wireless communication. When the mobile phone is used to send query short messages to the GSM communication module, the single-chip computer will control the G...

Abstract

The invention relates to the field of environment air quality monitoring, in particular to an air PM2.5 detecting device and method based on GSM wireless transmission. The PM2.5 detecting device based on GSM wireless transmission comprises a PM2.5 detecting module, a single-chip microcomputer minimum system module, a GSM communication module and a mobile phone display terminal. According to the PM2.5 detecting device based on GSM wireless transmission, the operation of inquiring the current air PM2.5 concentration value is easy and convenient, all-time remote inquiring of the air PM2.5 concentration value can be achieved simply by sending inquiring short messages to the GSM communication module with an SIM card in the device, and data transmission is fast and accurate.

Description

technical field [0001] The invention relates to the field of ambient air quality monitoring, in particular to an air PM value detection device and a detection method based on GSM wireless transmission. Background technique [0002] In recent years, people's requirements for living standards are not limited to basic necessities, food, housing, transportation, etc. The quality of the living environment has attracted more and more attention, such as PM2.5 content, air quality, temperature and humidity, etc., by detecting the environmental status, and timely release Bad environmental information can prevent various diseases caused by poor air conditions. With the industrialization of modern society, there are more and more factories, the global climate is warming, and the air quality is getting worse and worse. Therefore, the detection of air PM2.5 content has become an important link in the detection of environmental conditions, and it is also an urgent problem to be solved. B...
