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 ...

Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers ...

Abstract: Water distribution systems (WDSs) are essential infrastructures susceptible to cyber-physical attacks (CPAs) and thus require advanced defense mechanisms. This study introduces a novel, ...

If you're savvy and want to do a bit more home monitoring, these interesting sensor ideas might be worth trying.

Abstract: Wireless Sensor Networks (WSNs) are essential for many applications, but because of their limited power resources, they confront major energy efficiency difficulties. This research offers a ...

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 ...

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.

In a development that could transform how scientists study cancer, neurodegeneration and inflammation, researchers have invented a new sensor that enables MRI machines to visualize molecular activity ...

The Dabao open-source hardware board features a Boachip-1x RISC-V MCU, whose RTL Verilog files are also open, and is IRIS inspectable.
