l  Introduce

IR-5000 is a reflective photoelectric sensor module, the core port is a TCRT5000 sensor. The TCRT5000(L) has a compact construction where the emitting-light source and the detector are arranged in the same direction to sense the presence of an object by using the reflective IR beam from the object. The operating wavelength is 950 mm. The detector consists of a phototransistor. The following is a description IR works.

The light emitting diodes constantly emits infrared light, when the emitted infrared not being reflected back or reflected back but the strength is not big enough, the phototransistor has been in the off state, the output end of the module is low. When the object to be detected is the presence within the detection range, and intensity of the reflected infrared rays are sufficiently large, the phototransistor is saturated, the output of the module is high. Then we can identify the high or low of output through the microcontroller, and do some relevant action by program.
