This design was done to get a sealed keypad for very wet environments (in my particular case, showers for swimming pools). The keypad needed to be able to detect slight pressure on a stainless steel ...

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 ...

The design behind leak sensors is actually pretty cool: essentially, most sensors have two or three metal probes that, when they come in contact with water, detect increased conductivity and set off ...

Abstract: Inspired by water gerridae’ micro-wave detection ability, this study developed a miniature portable sensor, bionic water wave sensor (BWS) based on flexible polyvinylidene fluoride (PVDF) ...
