Here is a Youtube VLOG of my DIY RO Water Purifier Controller done via Arduino UNO. I want the Arduino UNO to control the RO pump, so that it pumps for a specific duration and stops automatically. This is done via Opto-isolated 4 Channel 5V 10A Relay Board meant for Arduino UNO, Raspberry Pi or similar SoC boards which offers GPIO pins. To this relay I have connected the RO water purifier booster pump which works at 24V DC connected via 220V AC to 24V DC power supply adaptar. I have also connected a small active 5V buzzer to notify the progress and completion as it fills the tank/canister.
