This　paper　presents　a　low-power　real-time　air　quality　monitoring　system　based　on　the　LoRa　Wireless　Communication　technology.　The　proposed　system　can　be　laid　out　in　a　large　number　in　the　monitoring　area　to　form　sensor　network.　The　system　integrates　a　single-chip　microcontroller,　several　air　pollution　sensors　(NO2,　SO2,　O3,　CO,　PM1,　PM10,　PM2.5),　LongRange　(LoRa)-Modem,　a　solar　PV-battery　part　and　graphical　user　interface　(GUI).　As　communication　module　LoRa　sends　the　data　to　the　central　monitoring　unit　and　then　the　data　would　be　saved　in　the　could.　The　range　tests　at　an　outdoor　area　show　that　LoRa　is　able　to　reach　to　approximately　2Km.　The　TX　power　is　only　about　110mA　which　is　lower　compared　with　other　used　wireless　technology.　An　easy　to　use　GUI　was　designed　in　the　system.　Based　on　LoRa　technology,　GUI,　and　Solar　PV-battery　part　the　system　has　several　progressive　features　such　as　low　cost,　long　distance,　high　coverage,　long　device　battery　life,　easy　to　operate.　©　2016　IEEE.
