Aiming at electric vehicle traction inverters, LEM has managed to shrink a 1.5kA current sensor into 29 x 21 x 12mm and 27g. “HSTDR current sensor is significantly more compact than a traditional C-core sensor, making it much easier to be integrated into space-limited inverter boxes,” said LEM. The technology is open-loop Hall effect and the core, integrated bus bar ...

Micro Crystal has introduced a ±1°C temperature sensor that includes a real-time clock, draws only 160nA (3V), and is automotive-approved. Called RV-3032-C7, it comes in an hermetically sealed reflow solderable 3.2 x 1.5 x 0.8mm ceramic SON-8 package – which is Pb-free, RoHS compliant and AEC-Q200 qualified. It is actually a module, as the company, a division of Swatch, has ...

Infineon has announced IM69D128S, a mems microphone for wearables, phones and IoT devices, emphasising its 520μA consumption and 69dB(A) signal to noise ratio. By switching clock frequency to trade bandwidth and SNR, the microphone can also be operated in a 420μA power saving mode and a 180μA in low power mode. There is also a 25μA (50μA max) stand-by with ...

Edinburgh-based Photon Force has added an optics option to its single photon avalanche diode (SPAD) array camera to increase sensitivity. “Customers now have the option to specify microlensing for their SPAD array camera,” according to the company. “The microlenses offer an improvement of more than 10x in effective fill-factor, enhancing the sensitivity of the camera for time-resolved measurements. This works ...

GNSS RTK 2 is a multi-band GNSS sensor plus integrated inertial measurement unit and sensor fusion for industrial applications, build in Mikroe’s 57 x 25mm Click board format. Based on Ublox’ ZED-F9R professional-grade GNSS positioning module, it can receive signals from GPS, Glonass, Galileo and BeiDou “plus SBAS and QZSS satellites can be received concurrently”, according to Mikroe. “Built-in algorithms ...

Bosch Sensortec announced four sensors all on the same day at CES in Las Vegas. BMP585 (right) is a toughened liquid-resistant barometer for altitude tracking in wearables. With a liquid-proof gel cover, it can be exposed to salt water and chlorinated swimming pool water – as well as dust, for example as part of a vacuum cleaner. “It includes all the ...

IAM-20685 is the smallest ASIL-B-compliant monolithic 6-axis MEMS inertial measurement unit in production, according to TDK, and it was developed in compliance with ISO 26262 for automated vehicle parking, for example. It “enables parking-assistance systems to determine the vehicle’s motion and vision systems to enable stabilisation techniques and improve image quality, and for positioning systems to enhance absolute position accuracy,” ...

Infineon is extending its collaboration with the NGO Rainforest Connection (RFCx) for monitoring vulnerable regions of the earth with sensor technology. At the heart of the Rainforest Connection’s work are Guardian devices powered by solar electricity. These devices transmit live sound recordings from rainforests. Artificial intelligence is used to analyze the data, detecting sounds of threats. When the sound of ...

Gesture systems can allow drivers to keep their eyes on the road while controlling in-vehicle systems, says Mark Sand of Texas Instruments. There are many options for adjusting various comfort and convenience functions in a vehicle, but manipulating the buttons, knobs and especially touchscreens requires drivers to divert their eyes. Gesture detection allows a swipe of the hand to afford ...

Rohm has developed a 30mW artificial intelligence IC with on-device learning capability for edge processing – 30mW here is an example power, dependent on algorithm running. “Until now it has been difficult to develop AI chips that can learn in the field consuming low power,” according to the company. This one is intended to use “artificial intelligence to predict failures ...
