Text Book of an Automatic Solar Powered Irrigation Farming System - Bok av Auwal Mato - Häftad
This project present the design and construction of Automatic solar powered irrigation farming system using NE555 Timer, 7404 HEX inverter, Transistor SK100 and Relay, the system will work when two probes which are connected to the circuit are placed/inserted in to the soil, two probes will conduct only when the soil is wet (resistance is low) and they cannot conduct when the soil is dry due high resistance. The voltage is given from the battery connected to the circuit. When the soil is dry it will..
