I was actually a bit surprised as the design of this acoustic light sensor/switch module is based on a special IC, which I have seen for the first time, rather than using a cheap OTP microcontroller ...

The sensor integrates three functions of ambient light sensing, proximity detection, and light source flicker detection. As a result, it provides a complete ‘under the OLED screen’ (BOLED ...

Lidar—short for light detection and ranging—is the visual cortex of many modern autonomous systems. It works by firing pulses of laser light (often in the near-infrared spectrum) and measuring ...
