IOT BASED TOXIC GAS MONITORING AND CONTROLLING IN SEPTIC TANK

Abstract

In septic tank system, density of toxic gases such as hydrogen sulphide, Methane, carbon monoxide etc. are continuously monitored by the gas sensors and analysed in graphical format in Thingspeak. If the toxic gases go beyond permissible exposure limit (PEL) then, the controller will send notification to user/concerned officials of public work department to clean the septic tank system.Moreover our system will automatically pump out the gases and desulphurise the toxic gas and store it in storage unit once the values of toxic gases are nearer topermissible exposure limit and thereby it will try to decrease the density of the toxic gases. Therefore, by using IoT based septic tank system, it is possible to avoid abnormality in septic tank and more importantly  death of manual scavengers due to toxic gas exposure (asphyxiation).
