Abstract

This hydroponic project describes the development of hydroponic system by using solar panel to control the water pump, solenoid valve and cooling fan. It involves a combination of electrical, electronics and agriculture into one sustainable system which consists of a solar panel, solar charge controller, temperature sensor (thermistor) and water level sensor (pump and valve). Since this project is being conducted in East Cost’s area, so total voltage of one solar panel may absorbs is 10 to 11V DC. To solve this inadequate amount of voltage, solar panels 18V DC is used. The voltage depends on light capture by solar panel. Weather can minimize the light capture by solar panel thus affect the overall performance. NESS5 ICs are used to control the operation of hydroponic system for water level sensor (high and low), and also op amp IC741 is used to sense temperature surrounding in hydroponic system for cooling process.
