This paper investigates the effect of the input current and the distance of separation between the IR transmitter and IR receiver on the voltage detected by infrared (IR) receiver Line-of-Sight IR propagation. The research was carried out using IR533C IR transmitter and FDS 100 IR receiver. Regulated digital power supply was used to provide stable 5V supply to the transmitter circuit. A 5V, 100kHz square wave from the signal generator was used to switch the BC338 transistor to modulate the frequency of the IR transmitter. The resistance of the potentiometer was varied from 27Ω to 117Ω. Two high precision digital voltmeters were used in the measurement of the detected voltage and the voltage drop across the potentiometer. The IR transmitter input current was calculated by dividing the voltage drop across the potentiometer by the potentiometer resistance. The distance separating the IR transmitter and IR receiver was varied from 1.4cm to 4.4cm. From the result obtained, it was observed that the voltage detected by the IR receiver increases with the increase in the magnitude of the input current applied to the transmitter. It was also observed that the magnitude of the detected voltage decreases with the increase in the distance separating the transmitter and receiver
