REFLECTANCE BASED PROXIMITY SENSOR USING SI1102
This reflective sensor module is a high-performance 0-5 cm active proximity detector. The sensor can provide a range up to 50cm with higher current infra-red LED and current limit resistor R2, R4 used across IR LED. Because the sensor operates on an absolute reflectance threshold principle, it avoids the ambiguity of motion-based proximity systems. The Si1102 consists […]
