Since the earliest days of microelectromechanical systems (MEMS) sensor products, the goal of easily combining the sensing structures made using MEMS processing with the required signal conditioning has driven many sensor R&D labs. If successful, the solution would make the resulting devices more useful in a broader range of applications. In the 1980s, the circuitry […]
What are the types and uses of vibration sensors?
There’s a wide range of vibration sensor technologies, and each technology has unique performance characteristics that make it suited for a specific type of applications ranging from mobile devices to machine condition monitoring and automotive safety testing. This FAQ reviews vibration and accelerometer sensor technologies including charge mode versus voltage mode piezoelectric sensors, MEMS devices, […]
What are the subtleties of using accelerometers as vibration sensors?
Accelerometers are deceptively simple-looking devices but are complex electromechanical systems. But there are numerous mechanical, environmental, electronic, and application-related factors to consider when using accelerometers. This FAQ reviews several of the subtleties that need to be considered when using accelerometers as vibration sensors and closes with a look at the ISO/IEC/IEEE 21451-4:2010 standard for Transducer […]
AI-enhanced accelerometers equipped with latest standard I3C interface
STMicroelectronics has launched three new accelerometers with advanced processing engines built-in to extend sensor autonomy, enabling systems to respond more quickly to external events while lowering power consumption. The LIS2DUX12 and LIS2DUXS12 leverage ST’s third-generation MEMS technology, adding programmable capabilities including a machine-learning core (MLC), advanced finite state machine (FSM), and an enhanced pedometer. A third entry-level […]
How do sensors improve home appliances? Pt. 2
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, […]
How do sensors improve home appliances? Pt. 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 […]
What are submersible sensors?
The International Electrotechnical Commission’s (IEC’s) standard IEC 60529 (and International Organization for Standardization’s ISO 20653) identifies the ability of an electronic device (sensor) to withstand water or dust intrusion with IP68, IP69 and IP69K ratings. An IP68 product should prevent or withstand water ingression for a depth exceeding 1 meter as specified by the manufacturer […]
How can sensors protect a diamond center vault?
In Belgium’s’ Antwerp Diamond District, eighty percent of the world’s rough diamonds passed through a three-square-block area. The Diamond Squad, the world’s only specialized diamond police, provided 24-hour police surveillance and 63 video cameras monitored the district. In this area, the Antwerp Diamond Center vault was thought to be impenetrable. In addition to having a […]
How do sensors impact ATMs?
It’s well known that automobiles and smartphones have several sensors to improve today’s capabilities over those of previous generations. However, they are not the only products that impact consumers’ lives to do so. For example, automated teller machines (ATMs) have a surprising number and different types of sensors to perform a variety of functions. Even […]
