Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technolo­gy has progressed to such an extent that refrigerators can now ...

In a previous post on this site, my colleague Steve Madara made the case that the current practice of managing data center thermal conditions based on pressure differential is outdated and inefficient ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Many sensors stop when batteries run out. These sensors get power from sunlight, heat, or movement and keep running for years ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables ...

A flexible wireless organic sensor system that transmits power and data wirelessly has been constructed by integrating organic devices on plastic films. This sensor will be used in new applications in ...
