Hi there, I have tried your circuit of automatic hand sanitiser dispenser without Arduino on the breadboard. But the issue is that I am getting an output current of 40mA. And for the pump, this should be from 130mA to 220mA. Is there any way to solve this issue..? Looking forward to your reply...
@@mission_critical I have already used an IRFZ44N MOSFET to amplify the output current of LM358 from uA to 40mA. So, should I use one more..? In that case, can you suggest any better MOSFET with a higher current gain?

Good job
Thank you mate

Use Relay / MOSFET to drive the output
