An environmental pollution monitoring system using LORA

LORA is based on technology of wireless systems and it is designed to transmit and receive desired data from a point to another point even in remote areas in absence of Internet. This paper provides an overview of LORA used in analyzing the air pollutants data from different sensors (CO
₂
, NO, CO, Temperature and Humidity) and locations of those areas by GPS module. Using an ARM7 microcontroller as an intermediate device of controlling and converting the analog data to digital data, thereby the controller is connected to LORA device and finally there is a LORA transceiver (receiver section) which is connected to the LORA configured PC to store and analyze the real time data for further use.
