Using the Infrared sensor switch (SN-E18-D80NK) or any of the infrared sensors. Can this be set up to detect the strength of the infrared received. Lets say anything above the threshold (>500) strength (either through light received or voltage produced) will switch on a light bulb and anything below will not. Does this make sense?
I've read that it can be used as a block or unblocked sensor, just wondering if this can be done.
