There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.

Optical sensors may be uniquely suited for use in robotic hands, according to Carnegie Mellon University researchers who have developed a three-fingered soft robotic hand with multiple embedded fiber ...

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.

Through the acquisition of Canadian company Real Tech, ABB expands its strong presence in the water segment and complements its portfolio with optical sensor technology critical for the age of smart ...
