Design and Implementation of Prevent Gas Poisoning from Sewage Workers using Arduino

Maintenance of sewage system is a cumbersome task which has to be carried out in regular basis since it is inevitable. Domestic practices will produce some organic waste like leftover food, wet waste etc.which are released into drains. This wastes will release some of the hazardous gases like CH
₄
, CO and H
₂
S. The paper implements an idea of detecting sewage gases which are harmful, hence prevents the people working in sewage systems from gas poisoning. The developed system is aimed to alert the sewage workers by using an Arduino Mega, gas sensors and GSM Module. The system monitors sewage gases continuously and when the content of hazardous gas hits the set threshold value the Arduino sends an SMS alert to the registered number. For the people present nearby the values are displayed on LCD display. The system also has an ultrasonic sensor to measure the depth of sewer. The threshold and Alert message are set by coding the Arduino Mega.
