Product Usage: 1, watt-hour meter pulse data sampling
2, fax machine paper shredder detection
3, barrier detection
4, black and white line detection
product description:
1, the use of TCRT5000 infrared reflective sensor
2, detection of reflection distance: 1mm ~ 25mm for
3, the comparator output, the signal clean, good waveform, driving ability, more than 15mA.
4, with the potentiometer to adjust the sensitivity
5, the working voltage of 3.3V-5V
6, the output form: digital switch output (0 and 1)
7, with a fixed bolt hole, easy to install
8, small board PCB size: 3.2cm x 1.4cm
9, the use of wide voltage LM393 comparator
Features:
TCRT5000 sensor infrared emitting diode constantly emitting infrared, when the infrared emission is not reflected back or reflected back, but the intensity is not large enough, the infrared receiver has been in the off state, the module's output is high, the instructions The diode is always in the extinguished state. When the detected object appears in the detection range, the infrared ray is reflected back and the intensity is enough.
Wiring:
1, VCC: Connect the positive pole of the power (3-5V)
2, GND: Connect the negative pole of the power supply
3, DO: TTL switch signal output
4, AO: analog signal output (different from the different output voltage, the foot can not usually take)
