Description

Connect VCC (3.3V-5V) and GND, the module power indicator will be on, and the infrared emitting diode of TCRT5000 sensor will continuously emit infrared rays. When the emitted infrared rays are not reflected or reflected but the intensity is not strong enough, the infrared receiving tube It is always in the off state. At this time, the output terminal of the module is high, indicating that the diode is always off. When the detected object appears in the detection range, the infrared light is reflected back and the intensity is large enough, and the infrared receiving tube is saturated. The output of the module is low, indicating that the diode is lit. The DO output interface can be directly connected to the IO port of the microcontroller, and is generally connected to an external interrupt. Analog output AO When the infrared signal of the transmitting tube is reflected and received by the receiving tube, the resistance of the receiving tube will change, which is generally reflected in the form of voltage changes on the circuit, and is processed after ADC conversion or LM324 and other circuit shaping Output. The change in resistance starts from the intensity of the infrared signal received by the receiving tube, and is often expressed in terms of the color (reflectivity), shape of the reflecting surface, and the distance of the receiving tube of the reflecting surface.

Correct wiring! Do not connect the positive and negative terminals in the opposite direction to burn the board’s electronic components. Arduino players should set the MCU’s I / O port to input mode / receive mode, otherwise it cannot be used. For other MCUs, or more control boards such as ARM, if you need to set the I / O port to input / output mode, you must set it to input mode / receive mode, otherwise it cannot be used. 51 series microcontrollers can be used directly without setting input / output mode.

TCRT5000 infrared reflection sensor is adopted, which is a photoelectric sensor that integrates transmitting and receiving. It consists of an infrared light emitting diode and an NPN infrared photoelectric triode. The detection reflection distance is 1mm-25mm. The sensor has a special M3 fixed mounting hole, which is easy to use and adjust the direction and fixation. Using a wide-voltage LM393 comparator, the signal is clean, the waveform is good, and the driving ability is strong, exceeding 15mA. It can be used to avoid obstacles for robots, and for robots to track white or black lines. It can detect black lines in a white background, and it can also detect white lines in a black background. It is a sensor for line-finding robots. Pipeline counting, watt-hour meter pulse data sampling, fax machine shredder paper detection, and many other occasions.

 

Application :

  1. Meter pulse data sampling
  2. Fax paper shredders detection
  3. Obstacle detection
  4. Black and white line detection
