Magnetometer features field shock recovery
Bosch Sensortec announces its next-generation magnetometer, the BMM350, which provides excellent performance with low current consumption to extend battery life. It enables a wide range of new use cases, including detecting head orientation for 3D audio, and pixel latency reduction in AR/VR to improve the user experience and avoid motion sickness. In indoor navigation, the […]
Magnetic sensors optimized for ADAS applications
Allegro MicroSystems, Inc. announced the launch of its A33110 and A33115 magnetic position sensors at the Sensors Converge Conference in San Jose, CA. Designed for advanced driver assistance systems (ADAS) applications that require high levels of accuracy and heterogeneous signal redundancy, Allegro’s newest sensors combine the company’s vertical Hall technology (VHT) with cutting-edge tunneling magnetoresistance (TMR) technology in […]
Teardown: Inside an industrial absolute encoder
If you go to the Wikipedia page on absolute encoders, you’ll find descriptions of these devices mentioning multiple code rings, glass or plastic discs, and configurations of sliding contacts arranged so each contact wipes against a metal disc at a different distance from a turning shaft. Actually, you’d be hard pressed to find any of […]
How can you see through walls?
It depends on what you want to “see” and how much you want to pay. To locate a stud, the old school technique of tapping a tool on the wall for acoustic differences used hearing rather than sight and it was free. Initially, battery-operated stud finders used magnets to find screws and nails and provided […]
How to optimize building and home automation designs to be more energy-efficient
By Brian Dempsey, system design engineer, Texas Instruments The numbers are a wake-up call: According to the United Nations, the buildings and construction sector accounted for 36% of the world’s energy consumption in 2018, contributing to a worrisome carbon footprint. And those percentages continue to grow. As a result, the race is on. Industrial design […]
Sensors and the future of food tech
Scientists and research engineers are developing technologies to boost food yield economically and efficiently in order to feed the world’s growing population. New ideas continue to emerge as the scientific community devotes time and energy in solving this problem. One futuristic approach involves creating an ideal environment for growing food in the air without soil, […]

The AS5270A/B devices are ideal for many automotive applications including brake and gas pedals, throttle valve and tumble flaps, steering wheel position, chassis ride-height, Exhaust Gas […]
Z-Series magnetic marker types for angle sensor applications
Novotechnik, U.S. introduces a selection of four magnetic marker types designed to suit various mounting applications for their RFC- and RFD- Series of touchless rotary angle sensors that provide absolute, rotary position. These two sensor families utilize a magnetic pickup to provide a touchless measurement range of 0° to 360° and makes measurements through air […]
What position is this thing in?
Associated questions could include: Has it moved? In what type of motion? How close is it? While accelerometers, gyroscopes and magnetometers provide inertial measurement units (IMUs) for position sensing in smart phones and other portable products, many other sensing technologies have been used to determine position, long before the smart phone. In industrial applications, more […]
