Wipe this down to rid any dust, grime, nose- or paw-prints from pets or greasy hand smudges from children. Clear the area surrounding the receiver's sensor of any obstructions like magazines, books, bric-a-brac or items near the sensor. The best/easiest way to increase an optical TRF CW receiver's sensitivity is to choose, for the receiver, a photodiode sensor with an inherent spectral response which more closely matches that of the transmitter, and to isolate the sensor from the load with some gain, which will keep its … Compared with the ordinary diode, it adopts great change in structure with a larger infrared receiving area, which makes the current increase accordingly. How a phototransistor works is it has 2 terminals, an emitter and collector. IR remotes send signals picked up and received at the IR sensor or receiver.
