I'm new to the components needed to do this. I'm still learning the basics so if anyone can help me do this project, I would highly appreciate it.
I'm building an Automatic Urinal System Flush that will sense the person for a duration and flush at the same duration.
For example, If a person is detected for a given period say for example, 10 seconds, after that if the person leaves, it will flush for approximately 10 seconds. The time should be a variable depending on how long it detects a person.
I'm using this diagram:
5V Supply Voltage > PIR Sensor > Op Amp (as Comparator) > 555 timer > Decade Counter (4017) > NPN Transistor (BJT for switch) > Relay > Water Pump.
Note: The PIR Sensor is not the Module type. I think it is IRA-E700
If you want clarifications please ask me about it. I would really appreciate it. I don't know how to make the circuit for Comparator up to the Decade Counter. Thank You in Advance
