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 ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

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 ...

Water wells are simple things, but that doesn’t mean they are maintenance-free. It can be important to monitor water levels in a well, and that gets complicated when the well is remote. Commercial ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Abstract: Flow Cytometry (FC) is a powerful technique used to detect and measure various cellular characteristics, including size, count, morphology, and DNA content. It plays a vital role in clinical ...

Abstract: Capacitance underpins a wide spectrum of impedance-based sensors, yet the usual method of using iterative finite-element modelling of frequency-dependent, fringing-field geometries is ...
