Remote Air Quality Sensing and Temperature Monitoring System using GSM for Smart City Application

The Global System for Mobile communication (GSM) is a digital mobile network which is used worldwide in mobile communication. In present days the GSM has been used in a different applications, like, in sending and receiving messages, medical services, data security, supply chain management, and so on. In this paper, an application based on a remote sensing mechanism along with a wireless communication system using GSM has been developed and tested. A temperature sensor is used to observe the abrupt change in the temperature in the environment and an air quality sensor is used to measure the existing pollution of air with respect to the harmful gas present in the air as remote sensing devices to monitor the environmental condition in real time. The sensor data has been converted into voltage signal and then fed to the Arduino ATmega328P which has been connected with the GSM modem SIM900A for remotely transferring the data into the client severs to notify as an SMS. Thus, the present system has been used as a real time air pollution detection system and fire detection system along with notification SMS at a control station as a step forward towards smart city application.
