I've been toying with an idea for a touch or proximity switching circuit(s) for controlling my motorcycle horn, starter, etc. a simple on/off signal to a relay or a module will work but I'm not sure about the following questions:
1. would an IR reflective sensor ignore ambient light changes? and would the passing of a finger or my hand do the trick in both day and nite situations? I'll post a link to one such sensor..IR reflective sensor link HERE
2. I saw a tiny capacitive sensor, round, panel mounted somewhere but can't find it now lol.. would this be better.??. altho it was 60 bucks and the IR reflective ones are typically 2-4 bucks in lots.
3. what associated circuitry is needed to run such sensors in a 12v system such as a bike??
I have a decent background but never did circuit design and would like it to be stable, long-life, vibration resistant.. etc... thanks for ANY responses in advance.
