Functions:
Electricity meter pulse data sampling
Fax machine, shredder paper detection
Obstacle detection Black and white line detection
TCRT5000 sensor of infrared emission diode constantly launch infrared, the infrared ray is emitted when the intensity of reflected back has not reflected or but is not much enough,
The light activated triode has been in the off state, the output end of the module at 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:
Using infrared reflection sensors TCRT5000
Test reflection distance: 1mm to 25mm
Clean the comparator output, signal waveform, driving ability is strong, for more than 15 ma.
Adjustable precision potentiometer to adjust sensitivity
Working voltage : 3.3V to 5V
Output form: digital switch output (0 and 1)
Fixed bolt hole, convenient installation Small board PCB
size: 3.2cm x 1.4cm
Use of wide voltage comparator
