Portable air quality detector

Abstract

The invention relates to a portable air quality detector which comprises a handheld device shell and a detection circuit module, wherein the detection circuit module comprises a microprocessor module,a data acquisition module, a signal preprocessing module, a data storage module, a data display module, a wireless communication module, a positioning module and an abnormity reminding module, wherein the data acquisition module comprises, but not limited, a carbon monoxide sensor, a temperature sensor, a humidity sensor, a PM2.5 (Particulate Matter 2.5) detection module, a VOC (Volatile OrganicCompound) detection module and a photoelectric smoke sensor; the signal preprocessing module comprises a signal filtering circuit, a signal amplification circuit and an A / D (Analog-to-Digital) conversion circuit. By adopting the portable air quality detector, PM2.5, VOCs, CO concentrations, smoke amounts, humidity and temperatures in the air can be monitored in real time, corresponding values areoutput through an LCD (Liquid Crystal Display), variation of living environments can be clearly noticed, people can take corresponding measures, then a healthy living environment can be maintained, and accidents can be avoided.

Description

technical field [0001] The invention relates to the field of air quality detection, in particular to a portable air quality detection instrument. Background technique [0002] People pay more and more attention to the quality of family life. Harmful gases are a great threat to people's health, such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol, cigarette smoke, flavors, etc. These harmful gases Monitoring is still far from perfect, and it is often detected after accidents and diseases occur, so it is necessary to do a good job of prevention. The living environment is the basis and guarantee of people's life. With the increase of urban population and the deterioration of the environment, the indoor air quality is gradually declining. People pay more and more attention to their living environment and start to use environmental detectors to detect their living environment. At present, the common ambient air quality detection device uses a sensor to dete...

AI Technical Summary

Problems solved by technology

At present, the common ambient air quality detection device uses a sensor to detect the quality of the air, and calculates according to the detected environmental data through an internal processor and displays the result on the display screen. However, the detection result of the ambient air quality detection device is Through manual transcription and entry, the data cannot be directly sent to the central controller, which will cause the detection data to be easily changed during manual transfer, which has a high error rate
