The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Abstract: Hydroponics is a new breakthrough in farming because it no longer uses soil as a planting medium, and uses water instead. In the hydroponic system, the fertilizer used is mixed into water, ...

An EC-37B Compass Call has flown for the first time with a mission system re-hosted from the aging fleet of EC-130H aircraft currently flying the aircraft’s eavesdropping and electronic attack mission ...

State energy codes in the United States, which must be at least as stringent as the ASHRAE/IES 90.1-1999 standard, require automatic shutoff of lighting in commercial buildings greater than 5,000 ...
