Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.
As shown in figure 1, a kind of wireless PM2.5 monitors of LoRa, including main control MCU, PM2.5 dust sensors, LoRa without
Line transmission chip, wherein compatible with GPS positioning chip, compatible with GPS positioning chip and main control MCU, PM2.5 dust sensors and master control
MCU is communicated by serial ports, and LoRa wirelessly transferred chips and main control MCU are communicated by SPI.
The wireless PM2.5 monitors of LoRa of the present invention, using model STM32L031 singlechip chips as main control MCU, adopt
With the LoRa chips (country) of SX1278 or the LoRa chips (foreign countries) of use SX1276 as wirelessly transferred chip, additional Jinan
The PM2.5 dust sensor SDS018 of Nuo Fang Electron Technology Co., Ltd, using solar panel as power supply unit, work
Voltage 5V.
The data that SDS018PM2.5 dust sensors will be collected receive to main control MCU chip, MCU by Serial Port Transmission
To after signal, base station is sent to by the LoRaWAN agreements of standard by LoRa chips, after base station transmits data to data again
Platform and Surveillance center, complete the collection of PM2.5 data.Compatible with GPS chip of the present invention, the region for needing intensive monitoring, one
As city use without GPS chip equipment.GPS chip uses UBLOX_G7020 chips, is led to by serial ports and main control MCU
News.
LoRa is wireless, and PM2.5 monitors use service intermittent mode, and every 4 hours (can be carried out by LoRaWAN backstages
