4. Working Principle
The photo interrupter module operates based on light beam interruption:
- Power Connection: The module connects to a power supply via GND and VCC ports, operating within 3.3V to 5V to ensure proper functionality.
- Signal Control: When the light beam between the emitter and receiver is blocked, the module outputs a high-level signal; it outputs a low-level signal when the beam is uninterrupted.
- Connection Configuration: The red anti-reverse connector and matching cable ensure safe and efficient connections, minimizing wiring errors.

5. Pin Description
| Pin Name | Description |
|----------|-----------------------------------------------------------------------------|
| VCC | Positive power supply (3.3V to 5V input) |
| GND | Negative power supply connection |
| S | Signal output pin; outputs high level when light beam is interrupted |

- VCC: Connects to the positive terminal of the power supply. Ensure the voltage remains within 3.3V–5V to prevent damage.
- GND: Connects to the negative terminal (ground) for stable operation.
- S (Signal Pin): Outputs a high-level signal when the light beam is blocked, and a low-level signal when uninterrupted.

6. Application Scenarios
The Keyes 2021 DIY Electronic Brick Photo Interrupter Module is widely used in:
- Education: Teaching optical sensing principles and signal control in electronics courses and experiments.
- DIY Projects: Creating light-based triggers for interactive electronic devices and security systems.
