Engineers at Queen Mary University of London have built a new color-changing tactile sensor, which allows robots to "see" and touch in real-time. The novel idea was invented by Giacomo Sasso, a ...

We tested the new Project Aura smart glasses to see if the lightweight design and Android XR features justify the premium ...

Arduino driver for the Pixart PMW3901 optical flow sensor. The driver is developed to support the Bitcraze Flow Breakout board. It communicates with the sensor using SPI. The library is using the ...

Abstract: In this study, a portable optical instrument was designed and developed for real-time nondestructive determination of fruit ripeness. A prototype of the instrument using inexpensive parts ...

This research is aimed to explore the efficacy and comparison of low-cost light sensor measurements for agricultural applications. For this reason, TSL2561, BH1750, and TEMT6000, low-cost light ...

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost ...

Fiber Bragg Grating (FBG) sensors are optical fiber devices in which a periodic modulation of the refractive index is inscribed along the doped silica core of a single-mode fiber. The fiber consists ...

For setups that rely on stored water, clear awareness of tank level and water quality is essential. Traditional level monitors are often bulky offline devices with only simple LED indicators, while ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

The TCRT5000 sensor is an infrared reflective sensor. This library is written to use with a TCRT5000 breakout's analog output and handle a threshold in software. These breakouts have typical two ...
