In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

This detector circuit uses just the Arduino Nano itself, no added sensor. Blowing some air from 30cm distance can be detected. It detects via measuring the internal heated chip temperature with 0.01 ...

Abstract: This paper presents the performances of rainfall energy harvesting through the use of a piezoelectric transducer and an Arduino-based measuring system. Different studies agree on the ...

Researchers have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, ...
