NettetDirect DC IR LED emitter to a phototransistor path only works for a short distance (1m) You can increase that with the square root of drive current due to distance inverse square law. If you want a high gain receiver for long distance then you need to modulate in the 30~50KHz range with a matched IR Rx part just like most IR remote controls.
