基于LoRa无线射频技术的室内环境检测系统设计OA

Aiming at the problem that new residential building environments require human handheld instruments to detect harmful substances such as TDI,TVOC,formaldehyde,PM2.5,etc.,a design scheme for indoor environment detection system based on LoRa wireless radio frequency technology is proposed.When no one is indoors,the system has built-in various environmental detection sensors to collect data information of indoor pollutants and perform characterization analysis.When the detected pollutant concentration is higher than the set threshold,the current measurement value is sent to the receiving board in a two-way interactive manner through the LoRa wireless transmitter board,and the data is remotely sent to the Web and mobile terminals with the help of the integrated GPRS communication module,which is convenient for detection personnel to remotely monitor the indoor environmental quality in real time and improve the accuracy of detection data.
