This 4 Channel IR Reflectance Sensor includes 4 independent IR sensors. Each IR reflective sensor is composed of an IR emitter and a receiver, if something is in the measuring range, the sensor will output a signal. There are also 4 potentiometers on the board which allows for adjustment of measuring range.
Features:
- Supply Voltage: 3.3 to 5.5V
- Supply Current: 1A
- Measuring Range: 1mm to 60mm
