Description
TCRT5000 sensor of infrared emission diode constantly launch infrared, the infrared ray is emitted when the intensity of reflected back has not been reflected or but is not big enough, the light activated triode has been in the off state, the output end of the module at this time for the high level, indicating diode has been put out state; Detected objects appear within the scope of testing, infrared light is reflected back and strength is enough big, light activated triode saturation, at this time the output of the module for the low level, instructs the diode lights.
Features
1. Detect the distance and test the white paper about 2 cm. The different distances of different colors are whiter.
2. Power supply voltage: 2.5 volts to 12 volts, no more than 12 volts (Note: The power supply voltage is low, the power supply voltage is too high, the sensor life will be shorter, and the 5 volt power supply is the preferred power source).
3. Working current, 5 V 18-20ma. After many tests, the sensor hardware is set to the best performance of the current working 18 mA and 20 mA, mainly in the anti-capacity interference. If you need small power consumption, we can modify it, at least they can do 5 mA. A message can be displayed.
4. The detected object, the final output signal level is low; no object is detected, and the final output signal is high.
5. TTL level sensor output, can be directly connected to the microcontroller IO port 3.3 volts or 5 volts.
Use for:
- The electricity meter pulse data sampling
- Fax machine, shredder paper detection
- Obstacle detection
- Black and white line detection
