Abstract: Waste generated from many sources are disposed or buried on an open ground, which increases the soil pollution and degrades fertility. Kitchen waste can be efficiently handled to produce biogas. There is a large amount of kitchen waste that is being generated daily and there is no proper system which uses this type of waste effectively. Conventional biogas facilities are inefficient and produce little methane because they rely on low calorific inputs such municipal solid waste, distillery effluent, and animal manure. Although it has not yet been fully exploited, biogas produced from kitchen trash is regarded as a high-calorie feed. It can replace half of the LPG used in cities and works in parallel with expensive and difficult to operate cow dung-based biogas plants in rural regions. In order to generate efficient gas from kitchen waste the pH value in a digester (of plant) should be neutral (i.e., pH=7) and temperature should be around 30℃ to 40℃, so it is essential to monitor the digester and after monitoring it is essential to check the amount of gas generated using gas sensors interfacing to ESP32 microcontroller and displaying the result in LCD.
