An embedded controller based system with feedback mechanism, for regulating a liquid content in a porous medium, such as soil. The real-time embedded system continuously detects the liquid content in the medium, by a sensing circuit. The controller is programmed to switch on a pump in the system to dispense the liquid when the liquid content in the medium is same or below a programmed lower limit, until the content reaches a programmed higher limit. The application for the system is particularly to control moisture content in soil, for plantation purpose.
