Photo Reflective Sensor Module (CNY70)
2.25 $
The photo-reflector consists of a GaAs infrared light-emitting diode and a silicon planar phototransistor. When an object is placed right in front of the sensor, the reflective infrared light emitted from the emitter will be picked up by the phototransistor and then output logical HIGH or logical LOW according to the distance between the reflection surface and the sensor.
Features :
- Using a wide voltage LM393 comparator.
- The working voltage of 3.3V-5V.
- Maximum output sink current 10mA.
- Operating range 0~5mm.
- Output is active low i.e an interruption produces a low output (LED is activated).
- Two (Ø 3.5mm) mounting holes for easy installation.
- It is compatible with Arduino board.
- Dimension: 38 X 17 X 17mm.
