Why System Performance Depends on TX/RX Matching
Reliable sensing performance requires proper matching between IR transmitters and receivers.
Transmitter power, beam angle, and wavelength directly influence the effective transmission range.
Receiver sensitivity, optical filtering, and signal decoding capability affect noise immunity and detection reliability.
Mismatch between TX and RX can cause false triggers, unstable response, or missed detections.
Reliable systems require TX and RX to be evaluated together under actual operating conditions.
IR TX&RX Configuration considerations
• Detection distance and response speed
• Ambient light and EMI conditions
• Modulation and decoding methods
• Mechanical calibration and installation
• Power consumption and duty cycle

In some cases, yes — but only after evaluation. Small differences in optical or decoding behavior can significantly affect system reliability.
No. Excessive distance margin often increases sensitivity to ambient light and misalignment. Reliable systems prioritize repeatability over maximum range.
The evaluation may indicate limitations or required adjustments. This helps avoid unstable designs before production decisions are made.
