Scientists achieve 100 particle bunches per second with their new KALDERA laser, a major step towards practical, compact ...

Laser-plasma accelerators can accelerate particles over distances that are up to 1,000 times shorter than those required by ...

This concept involves a beam produced by a laser diode reflecting off the measurement object and being directed onto the sensor’s receiving element by optics. The position of the reflected light ...

Arduino Library for the SparkFun Air Quality PM1/PM2.5/PM10 Sensor - BMV080 The SparkFun Air Quality PM1 ... A special lens allows the laser to pass through the enclosure to take measurements. Note To ...

The best part of this blind stick Arduino project is that it’s easy to build, affordable and products similar to this, like Torchit has even been featured on shark tank. The ultrasonic sensor acts ...

This project uses Arduino, an LM35 temperature sensor, a buzzer, and an HC-06 Bluetooth module to measure ambient temperature, trigger an alarm when the temperature exceeds a certain threshold, and ...

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider.
