IR beam interruption sensor - LED 5mm - 0-25 cm
The motion detection sensor reacts to the interruption of an infrared light beam that is transmitted between the transmitter and receiver. The devices should be placed opposite each other, in a straight line. When a third element appears between them - the receiver informs about the beam interruption. The module is equipped with a 5 mm IR LED with an illumination angle of 20°. Beam interruption systems are used e.g. in measuring gates.
