Part 1 of this blog discussed sensors in the laundry room in washing machines and dryers. In the kitchen, similar to the laundry room, basic functions can be designed in using established sensing techniques. In the typical home, the refrigerator is the second-largest consumer of electricity (13.7%), with the air conditioner being number one. So, […]
Hall Effect
How do sensors improve home appliances? Part 1
Today’s home appliances are increasingly connected for remote monitoring and control and smarter due, in part, to numerous sensors. The sensors help even lower-end appliances implement their basic functions and, more importantly, enable smarter, top-end appliances. While sensors provide these capabilities for several home appliances, this two-part series will describe sensing functions for large appliances […]
What are the types and uses of position sensors?
Position sensing is a critical function across a wide range of applications, from robot drive chains to conveyor belts in supply chain operations to the swaying of wind turbine towers. It can take many forms, including linear, rotary, angular, absolute, incremental, contact, and non-contact sensors. Specialized sensors have been developed that can determine positions in […]

The Wiegand Effect at Work: from lab curiosity to versatile product
What is the Wiegand Effect? Ferromagnetic materials – such as iron, nickel, cobalt, or alloys containing these elements – have a special property: When samples are exposed to an external magnetic field, they become magnetized, creating a magnetic field of their own. Moreover, they remain magnetized when the external field is removed. Ferromagnetic materials vary […]
