Abstract
This project is a project control valve biogas with PID controller for the control pressure gas through a valve with a PID controller by studying the work of the feedback controller dedicated PID control and study their function. The microcontroller model Diu U Ono Volunteer Service (Arduino UNO R3 Microcontroller) on which the pressure sensor (MPXV7002 Pressure Sensor DUAL PORT), which are used to measure gas pressure in the pipeline. The researchers are interested in the control valve biogas from pig manure to biogas to produce electricity efficiently. And to promote and support the development of innovative technologies and renewable energy.
