Hi Guys,
Been doing a bit of reading here but a first time poster.
Anyway I was wondering if i can get some help regarding a timer i need and with the discussion around the PIC10F322 is this the IC for me.??
What i need is a low power circuit than can run on a small battery for 3+ years. (Battery can be "C" size or "D" size lithium if needed.)
This circuit will be a timing circuit;
When a pressure switch (S1) closes the timer starts (T1).
When the programmed time (T1) is reached it will output (O1) to power a MOSFET SS Relay to close a contact (Trigger in a data logger)
If S1 opens before T1 is reached then the process is reset and starts over.
After xx time (T2) is reached it will stop O1 regardless of S1 state.
When S1 opens the circuit does nothing, waiting for S1 to close again repeating the process.
T1= approx 1min
T2= 3-5 mins.
This logic i know should be able to be done easily with the data loggers firmware however it is locked down and there is no other way other than a seperate circuit.
Hoping someone can assist.
Thank you in advance.
