Other than what I have learned from my basic circuits course, I do not know much about the topic in general.
I have a project that my boss had given me today JUST before I left work. And, he expects me to have a sketch/plan by Thursday to present at a meeting. It isn't a formal presentation or anything, but I am stuck. So please help if you can.
The dilemma is that we need to replace a photodiode, which we use to turn on the system in our little project. The photodiode is programmed to sense infrared light to turn on, however, as infrared light is also present in any visible light, if the system isn't in the complete dark, it depletes our battery. (We have to have it running on standby/off for approx. 2 years, so you can see the issue.)
A dome-like silicone cover encases our circuit board and battery. What we may want to do is replace the photodiode with a switch. Perhaps a simple membrane key that, when pushed, can have a wire touch the battery to activate it? (Not sure, as when he was explaining, his hand was covering his very vague diagram.)
I considered maybe using a latching switch? But, as I know almost nothing about circuits, at least not in an innovative sense, I was hoping I could get your input.
Thank you!
If the sketch is needed I will be happy to provide it tomorrow... and by sketch I mean the one my boss did... I'd reproduce one but I'd have to understand it first.
