基于单片机的空气质量检测仪的设计与实现

AbstractWith the development of the times and the advancement of science andtechnology,family residence is a key area in people's daily lives and hasattracted widespread attention.Especially in the past few years,the pollution ofthe external living environment has become more and more frequent.Peopleexpect that their residence can provide a better environmental condition for theirresidence while meeting their daily living needs.An air purifier is needed in life.This purification equipment can purify the air very efficiently,concisely andconveniently,and it is convenient for home use.This device can also realize theinteraction between devices.The home air quality monitoring system designed in this article can detectthe modern home living environment.STC89C52 is used as the systemcontroller,which contains temperature sensors and humidity sensors to collectambient temperature and humidity and PM2.5 data,and the system uses TheLED screen displays the data,and also includes different parts such as soundand light alarms and key configuration.The system uses and sensor software tocollect the data in the environment and display it in real time.If the collecteddata does not meet the relevant standards,an alarm will be issued to inform thepeople at home.After using the system designed by it,simulation was carriedout under the PROTUES environment,which confirmed the scientific andreasonable design.This system has strong practical value and economic value by virtue of theproducts already in the cash market and the scientific research results ofenvironmental quality monitoring.It provides a new method and way for thefurther development of smart homes in the future.Keywords:Single-Chip-Micro-compute Air-quality Sensor
