The MAX471 is an older current sensor which can handle up to 50 Watt, with a maximum of 25 Volts or a current of 3 Amperes. It is officially not supported any more however there are still many for ...

Abstract: A novel solar blind ultraviolet (UV) sensor based on a gallium oxide (Ga2O3) thin film-coated hollow core fiber (HCF) is first proposed by theoretical and experimental methods. Ga2O3 thin ...

Abstract: A novel optical fiber-coupled waveguide grating chip device based on Fano resonance effect is proposed and demonstrated for the first time, to the best of our knowledge. It is fabricated by ...

Building a DIY Arduino game controller requires specific hardware components. The table below lists all the components required to build the Arduino Uno game controller project. These components are ...

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 ...
