Counting thermostats opening and closing
Counting thermostats opening and closing
(OP)
I've made a test rig that tests thermostats opening and closing.
I have fifteen stats on test. I'd like to count the switches opening and closing. Can I put a small DC voltage through the switches and measure this going from +V to 0 and counting the pulse.
Is there something on the market I could use? Nice and simple as I am a meterials engineer not a programming/hardware wizard!

Some can sense a low to high voltage transition.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
