Honeywell has created a tough six-degrees-of-freedom inertial measurement unit for heavy-duty and off-road vehicle applications. TARS-IMU, as it is called, comes in two versions: 5V or 9 – 36V, and includes a sensor-fusion algorithm. “The sensor fusion algorithm can be customised for specific vehicle applications via on-board firmware, allowing movement data to be filtered to minimise unwanted noise and vibrations,” ...

Bosch is trying to push accelerometers and gyroscopes into lower-cost applications with an IMU (inertial measurement unit) called BMI323, which includes pre-developed function algorithms. “For example, BMI323 already includes Bosch Sensortec’s plug-and-play step counter software, so customers don’t need to spend time developing their own algorithms”, according to the company. “Other features include motion detection that can turn sub-systems on ...

InferSens of Cambridge is to see the first use of its AI sensing technology early next year, in a battery-powered, water flow and temperature sensor for estimating Legionella risk in water systems. Not requiring a cloud connection, it uses local processing and can be attached to the outside of a pipe without cutting or plumbing, said the company. It will ...

Aiming at sensor fusion application development, Rutronik has created a single Arduino-compatible board with a plethora of sensors from Infineon, Bosch SE and Sensirion. Called ‘RAB1 – Sensorfusion’, “the board offers its own platform that allows machine learning based sensor fusion,” according to the company. “Thanks to the components and the possible intelligent combination of sensor values, the board is ...

Alps Alpine is aiming at safety redundancy, particularly in vehicle power steering, with a pair of magnetic angle sensors on two separate die inside the same package, positioned to share the same external magnet. “Redundancy design is increasingly a requirement for automobile driving systems,” according to the company. “The use of multiple sensors was once the typical way of realising ...

Industry 4.0 technologies have transformed manufacturing processes but have added challenges to the business of ensuring worker safety which can be met by smart sensors and ASICs, says Richard Mount from Swindon Silicon Systems. By turning towards automation to complete many repetitive activities, Industry 4.0 processes drastically reduce opportunity for human error — frequently cited as a major cause of occupational ...

Bosch Advanced Ceramics is making Wheatstone bridges to measure deflection in pressure sensors. “It does this permanently and constantly,” said Bosch, “and, unlike electrical insulation or a metal resistor, the signal cannot be distorted with technical ceramics.” The image is a demonstration tile with eight ceramic Wheatstone bridges.

Danisense, the current sense transducer specialist, is introducing its DW series of closed-loop compensated zero-flux current transducer measuring up to 500A and offering excellent accuracy with 10ppm linearity and low offset at 15 ppm. To meet the increased requirements in terms of high frequency coming from the latest power conversion products based on wide bandgap semiconductor technologies such as GaN and ...

Diodes has announced precision bi-directional current monitors in a 2.2 x 2.2mm package. Called the ZXCT199 series, they are rail-to-rail voltage output type devices with gains of 50V/V, 100V/V or 200V/V. Input is taken across a shunt resistor at common-mode voltages from -0.1V to +26V (typically 120dB common-mode rejection), independent of the 2.7 to 26V supply voltage, from which a ...

CUI Devices has introduced ultrasonic transducers with ingress protection ratings of IP67 or IP68, operating up to 400kHz. There are 18 models, with beam angle spanning 7° to 80° and operational distance ranging from 30mm to 15m. “With combined transmit and receive functions in a single package, engineers can benefit from a simplified ultrasonic sensor solution for distance measurement, object ...
