PLC Based Automation of Biogas Plant

The research paper deals with the Automation of Biogas Plant which is processed by the technology or Automation tool of PLC (Programmable Logic Controller). Our main aim for the Biogas Plant is to control and monitor the various parameters in the plant like temperature, motor, pump, level, heater, buzzer, etc. Each of these parameters needs to be optimally managed to achieve greater efficiency. PLCs are armoured to serve conditions (dust, moisture, heat, cold etc.) & have the facility for extensive input/output (I/O) arrangement. PLCs read limit switches, analog process variables (such as temperature & pressure) and the positions of complex positioning systems. PLCs operate electric motors, magnetic relays or solenoids or analog outputs.
