In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with ...

Loading cement sacks into trucks requires precise counting for traceability, yet manual methods are error-prone and often ...

If you happen to be in the market for a small artificial sun, you may be interested to know that for about $1300, you can get a tennis-ball-sized LED array that outputs 120,000 lumens.

Abstract: In this paper, a study on bearing-only localization for wideband off-grid sources is presented by employing distributed sensor array networks. First, the wideband off-grid signal models ...

Abstract: Superdirectivity enables compact arrays to achieve high directivity, but its practical implementations are highly sensitive to physical imperfections. This lack of robustness hinders the ...

NeuroBand is a specialized smart safety armband engineered to provide timely assistance to elderly and high-risk individuals during emergencies. Its primary goal is to mitigate the risks associated ...

Densely packed arrays of electrical components called capacitors can form a high-fidelity vibration sensor that can be worn on the skin. Seungjae Lee is in the School of Energy and Chemical ...

Modern cars are loaded to the gills with advanced driver assistance systems supporting complex safety suites, a mix that essentially turns new vehicles into rolling sensor platforms. The pieces of ...

Easy-to-use interface for configuring and reading radar data. Supports both single and multi-target detection modes. Works with Arduino-compatible board that has a separate hardware UART.
