| It is a tensiometer based soil moisture sensor. It consists of a cylinder with piston connected to the tensiometer and a 6V DC battery and a 6V relay. The cylinder with a spring-loaded piston is connected to a piston rod. There are two brass strips, one connected to the cylinder and the other connected to the piston. A gap is maintained between the two strips, which is bridged when they move closed due to the suction created by the change in soil moisture. One of the brass strips is connected to the (- ve) end of the battery and the other brass strip is connected to the other (+ ve) end of the battery through the 6V relay, motor of the pump and a switch. | |
