Hello,
I'm looking for help in designing a device that can be aimed at a light source and measure the current level of light. This light level will be used as a threshold to monitor an increase in light intensity. If the level of light is exceeded by (x) amount, I need to activate a 12vdc relay output. The light level threshold needs to be set by pushing a button.
I've looked around, but haven't seen anything similar to this that s commercially available. If there is such a device I would appreciate directions on where to purchase. If not, I'm willing to build and experiment myself.
Thanks.....
