Apr 12, 2010· If not, then presumably you just need to add in a little something less IR permeable (aluminum?) between the tape and the sensor. Of course you could always open it up and cut the leads to the IR sensor (if soldered) or disconnect it (if not). I wouldn''t really recommend that option, though.
