Oil-tolerant pressure sensor meets AEC-Q100

Melexis has introduced two MEMS pressure sensors which exceed AEC-Q100 qualification requirements. They measure absolute pressure in demanding operational environments: operating over -40 to 150°C directly in conventional non-corrosive non-aggressive media, or incorporated into oil-filled sensor modules for increased robustness. MLX90815 is designed for best…

FRAM aimed at energy harvesting encoders

Fujitsu is aiming at energy harvesting by cutting the power consumption of its latest data-processing ferroelectric memory (FRAM). In particular: industrial automation applications involving energy harvesting rotary encoders – encoders that make their own power – interfacing to chips from iC-Haus, for example (see below). Called MB85RDP16LX, according to Fujitsu…

Gas sensors made on CMOS line

Cambridge CMOS Sensors is combining MEMS and CMOS processing to make MOX (metal oxide) gas sensors. Key to the technology is etching silicon to leave a thin micro hotplate. “The resistive micro-hotplates are fabricated using a high-reliability silicon dioxide membrane and include an embedded tungsten resistor acting as…

Gesture control IC recognises button pushes

AMS has a range of infrared sensors that will support four-direction gesture detection and Mobeam barcode emulation. Designed for touchless gesture control and display management the device’s gesture detector uses four directional photodiodes to sense reflected IR radiation. This is then converted into physical motion information including: velocity…

Contactless position sensor designed for reliability

A contactless rotary position sensor from ams is designed as a replacement for conventional rotary encoders. “In devices which use rotary knobs, the AS5601 and its paired magnet may replace a rotary encoder without any change to the host microcontroller or its application software,” said the supplier. The sensor is…

Freescale shrinks tyre pressure sensor

Freescale Semiconductor has introduced its smallest tyre pressure monitoring device. Weighing 0.3 grams, the FXTH87 IC integrates a dual-axis accelerometer, pressure and temperature sensor with 8-bit MCU/S08 microcontroller and wireless transceiver. Monitoring tyre inflation is a safety feature in today’s cars as it can prevent…
