The VCNL36828P features a vertical-cavity surface-emitting laser (VCSEL ... battery-powered devices, the sensor enhances proximity detection with a range of up to 200 mm while minimizing power ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

The Pi listens to a 3-axis accelerometer and gyroscope, a laser proximity sensor for obstacle detection within 6.5ft, and a pair of NOIR cameras. This data is processed by neural nets and OpenCV ...
