I am developing a prototype 12V system comprising a solenoid activated by a PIR sensor. I am looking for a timer device so that the power to the solenoid cuts 1 or 2 seconds after activation.
This is as a safety back-up. The PIR sensor should cut out after a minute but it's a bit long and sometimes the power to the solenoid is getting stuck on.
Would this timer be suitable RS Stock No.:.
