A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on ...

The tool will let you track NASA's modern lunar program during its 10-day flight around the moon and back again.

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 ...

There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or ...

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.

Dark matter will help explain not only how our universe was made, but also its components. It will help people understand fundamental physics and how additional particles and forces exist. The ...

For the millions of people living with end-stage kidney disease, hemodialysis is more than a medical procedure, it is a thrice-weekly lifeline that keeps the body's chemistry in balance. Yet even with ...

Ultrafast light switches offer interesting prospects for optical data processing, the researchers explain. The team's goal was to find a material whose reflective properties could be manipulated, or ...

Abstract: Optical fiber displacement sensors are extensively used in pre-warning of landslide and earthquake. Here, we propose a highly sensitive microdisplacement sensor based on sidewall resonance ...

From absolute beginners to advanced users — one library, two layers, full control. myDHT is a fully self-contained Arduino library for DHT11 and DHT22 temperature and humidity sensors, designed to ...

Cameras may soon see without lenses, and the change could be as profound as the leap from film to digital. A new imaging technology developed at the University of Connecticut promises to rewrite the ...
