IR diode transmitter sends out a continuous stream of IR ray. When

these rays hit an obstacle, it is reflected back to the detector transistor

lying next to it. If the reflected signal level is exceeding its setting an

indicator light will light up. If a sounder module is hooked up it will

produce an alarm.
