Description:
The Waveshare Photo Interrupter Sensor is a digital optical module featuring a 6mm detection gap and an integrated comparator for stable digital output. Operating on a 3.3V to 5V power supply, this sensor provides reliable logic-level signals (0 or 1) suitable for direct connection to microcontrollers like Arduino. Ideal for applications such as speed detection, position sensing, and pulse counting when used with an encoder disc, this compact module ensures accurate, real-time digital feedback for robotics and automation systems.
Specification:
- Power: 3.3V ~ 5V
- Dimension: 26.8mm × 15mm × 18.7mm
- Mounting holes size: 3mm
- Gap width: 6mm
Features:
- Infrared detection, eliminating the interference of external stray light
- Schmitt trigger for stable waveform and signal
- Signal output indicator (while breaking the beam, outputs low level; the indicator lights up )
Package Included:
- 1 x Photo Interrupter Sensor
- 1 x 20-slots encoder disk
- 1 x XH2.54 3PIN wire
