Self electronic sensor for controlling irrigation and evaluating humidity of soil, has sensor, which generates offset voltage by reference voltage, and relay is provided, which sends out electronic signal

摘要

The self electronic sensor has a sensor, which generates an offset voltage by a reference voltage. A relay is provided, which sends out an electronic signal, as the foundation of an integrated circuit that performs as a comparator of functions and investors. The power is supplied to an electronic circuit of the sensor through a small plate with solar connection rechargeable batteries.
