IR Sensor with time relay | All About Circuits

· After using this circuit i found water flow is fast and wastage of content is more when take off hands from IR sensor. So i thought to add a delay "off" after 2 or 3 sec it would save content or liquid. In previous attached photo i have Sensor, Normal relay and a timer relay i purchased. Some one gave me time relay circuit (attached) which i tried but when i connect 6V submersible pump ...

How to Connect an IR Photodiode Sensor in a Circuit ...

· So, I decided a proximity IR would work if I placed the sensor at the gate and put a reflector on the gate that would reflect the IR when the gate was opened. I saw your above circuit "How to connect an IR Photodiode Sensor". I bread boarded the circuit and it works fine. The only problem is it uses 50ma in standby mode and 70ma when active.
