These Safety plays a major role in today’s world and it is necessary that good safety systems are to be implemented in places of education and work. This proposed system modifies the existing safety model installed in industries and this system can also be used in homes, villages, cities and offices. Most of the drainage and unused wells are forming toxic gases. The main objective of this system is designing microcontroller based toxic gas detecting, alerting system and gas purification. The hazardous gases like H2S, CO and Methane will
be sensed and displayed each and every second in the web based application. If these gases exceed the normal level then an alarm is generated immediately and also an alert message (SMS) is sent to the authorized person through the wifi. The advantage of this automated detection and alerting system over the manual method is that it offers quick response time and accurate detection of an emergency and in turn leading faster diffusion of the critical situation using gas purification process convert a toxic gases into pure air. The garbage alerting system is used to control the air pollution. All the gas sensor values are continuously monitoring through the mobile application using wifi module. This system is very much useful to make a city smart as well as reduce the human death.
