The transformation of cities into smart cities is being done these days. Smart city initiatives responding to environmental problems such as air pollution ensure clean air. This paper introduces an automatic air quality monitoring system that monitors environmental conditions in real time. This proposed system is based on IoT technology and embedded systems. This system also includes electronic devices such as sensors to sense the environmental conditions and the Arduino Uno board for the system's performance. A LoRa module is introduced in this system for communication over long ranges. The communication modules such as Bluetooth, Zigbee, and Wi-Fi also can be used but LoRa is introduced in this system to communicate at long ranges. Bluetooth, Zigbee, and Wi-Fi are tended to be used for short-range communications as compared with the LoRa module. This project is a LoRa-based smart city air quality monitoring system the main purpose of this system is to monitor smart city environmental conditions such as temperature, humidity, rain, and pressure, and detect light and pollutants in the air. The values of these environmental parameters are stored on a cloud server that uses the LoRa Gateway for communication. Data can be monitored by the user from the cloud server and values are displayed in the form of graphs or tables.
