IR Sensors Module

Overview

IR sensors allow your mouse to detect maze walls using reflected infrared light.

Components

Part	Example
IR Emitter	INL-5AMIR15
IR Receiver	SFH313FA
MOSFET Driver	BS170 N-channel

Operation

• Emitters send IR pulses.
• Light reflects off maze walls and is detected by receivers.
• ADC converts analog voltage into distance readings.

---

Design Tips

• Place 4 sensors: Left, Front-Left, Front-Right, Right.
• Calibrate readings under your lab lighting.
• Use voltage dividers and pull-down resistors for clean signals.
