The sensor is really just an infrared photodiode inside of a tube. The diode is connected to an analog input pin on an Arduino. The sensor can be pointed at an object, and the Arduino can sense ...

pinhole and photodiode. The microscope is controlled by a Raspberry Pi (which controls an arduino to move the steppers). Tour guide at former Colorado gold mine fell out of elevator after ...

That means there would be major benefits from improving the efficiency of infrared sensors, such as photodiodes. Researchers at Aalto University have developed a new type of infrared photodiode ...
