An only slightly less simple followup circuit also ratios sensor capacitance to a reference capacitor to measure micrometers…this time linearly. Figure 1 The U1a and U1b cross-coupled Schmidt trigger ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

These are some great DIY projects that you can do for cheap.

Conventional vision hardware separates photodetection from computation, incurring substantial latency and energy costs. Chen and Di et al. report an optoelectronic architecture based on a ...

Broadband thermal radiation inevitably limits the performance of room-temperature infrared detectors. Here, the authors demonstrate an in-sensor background-offset cancellation mechanism enabled by ...

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really small, like ...
