Reflectance based Proximity Sensor using Si1102
https://www.electronics-lab.com/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 […]

Marktech Optoelectronics has announced the expansion of its surface-mount family of SWIR reflective sensors. The sensors are suitable for position sensing and detection applications, including card, barcode, edge sensing and money bill readers. Marktech surface-mount SWIR reflective sensors combine both a short wavelength infrared emitter and a high-sensitivity InGaAs photodiode. Emitted light from the sensor […]
