 Bigger Bigger  Smaller Smaller  Reset Reset

For the car management system I'm currently building I use a photoresistor to detect whether to turn on the lights or not.
And I'm wondering what would be the best way to mount the resistor in my dash as cleanly as possible...

Any suggestions?

A panel mount clip maybe ?!? If its thin enough, u can use a Metal, panel mount bezel one, if not a clip one is better given the circumstances.
A few images so u get the idea.

It's a possibility, but since the photoresistor isn't round I will still have gaps at the sides...

Maybe switch to using a phototransistor; some come in cases like 3mm LEDs, then you can use standard LED panel mount clips...

I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

Well, I've found lots of phototransistors in cases like 5mm LEDs, which would be ideal.
But they all seem to be intended for infrared smiley-confuse

Would one like this: http://www.datasheetarchive.com/SFH300-4-datasheet.html be suitable for detecting visible light?
It says it has a range from 420 to 1130 nm, but below 700 nm the sensitivity doesn't look all that great...

I have finally found what I need on ebay: http://www.ebay.com/itm/260940362637

They are already in an enclosure and their peak sensitivity is right in the middle of the visible range smiley
