High-Accuracy MEMS Sensors Target
Industrial Sensing Booth 716 at Sensors Expo 2018. STMicroelectronics has announced the release of new high-stability MEMS sensors with 10-year product-longevity assurance. The new sensors, to be made available this year, begin with the IIS3DHHC, a 3-axis accelerometer optimized for high measurement resolution and stability to ensure accuracy over time and temperature.
The IIS3DHHC targets precision inclinometers in antenna-positioning mechanisms for communication systems, Structural Health Monitoring (SHM) equipment for keeping buildings and bridges safe and stabilizers or levelers for a wide variety of industrial platforms. Its long-term accuracy and robustness are also ideal for high-sensitivity tilt and security sensors, as well as image stabilization in high-end Digital Still Cameras (DSCs).
ST's 10-year longevity commitment assures long-term availability of a wide range of high-performing components used in industrial equipment, helping vendors handle the typically long in-market lifetimes of their products and extended operation in challenging environmental conditions. In addition to industrial sensors, the program covers STM32 microcontrollers, motor drivers, analog components, power converters, LEDs and existing MEMS sensors that will be supported for at least 10 years.

Development of a New Debug and Test Tool - By William Holt, Sequim Tek
During a career largely spent developing mixed signal IC products, I often longed for a personal, simple to use, analog and digital pattern generator tool. Numerous occasions arose where it was necessary to check the performance or parameters of an IC, a breadboard or an application board. Sometimes the setup was trivial: a few supplies and a signal generator or two. And sometimes the setup was quite complex.
I had a few tools for the tougher problems but there was usually something not quite matching up---logic or interface voltages, offset, synchronization, limited pattern width/length and limited pattern control options. So after retiring, I decided to create a personal debug and test tool and here is the result. ...

Digital Pressure Sensors Boost Design Flexibility Booth 1110 at Sensors Expo 2018. All Sensors has announced a new line of digital pressure sensors: the ELVR Series. The new device series offers OEM customers increased design flexibility for pressure ranges from 2.5 to 75 mbar (1 to 30 inch H2O). The ELVR Series is a direct replacement to First Sensors' HCLA product line.
Product highlights include an I2C or SPI interface, an analog 0.5 V to 4.5 V output signal and significantly reduced position sensitivity. All Sensors' CoBeam2 Technology allows for greater sensitivity while reducing package stress. The ELVR sensors can communicate directly with microcontrollers, eliminating the need for additional A/D converters.
Versions of the ELVR are available with 3 V and 5 V supply voltages. The series is well suited for portable applications. A wide range of miniature SIP and DIP package options allows for flexible and space-saving PCB-mounting. Devices are available in bidirectional and unidirectional 2.5, 12.5, 25, 50 and 75 mbar pressure ranges.

Silicon APDs Are Optimized for LIDAR Applications
Booth 430 at Sensors Expo 2018. The Series 9 from First Sensor offers a wide range of silicon avalanche photodiodes (APDs) with very high sensitivity in the near infrared (NIR) wavelength range, especially at 905 nm. With their internal gain mechanism, large dynamic range and fast rise time the APDs are ideal for LIDAR systems for optical distance measurement and object recognition according to the time of flight method. Application examples include driver assistance systems, drones, safety laser scanners, 3D-mapping and robotics.
The Series 9 offers detectors as single elements as well as linear and matrix arrays with multiple sensing elements. The package options include rugged TO housings or flat ceramic SMD packages. The slow increase of the gain of the Series 9 photodiodes with the applied reverse bias voltage allows for easy and precise adjustments of high gain factors. For particularly low light levels, hybrid solutions are also available that further enhance the APD signal with an internal transimpedance amplifier (TIA). The integrated amplifier is optimally matched to the photodiode and allows compact setups as well as very large signal-to-noise ratios.

Barometric Pressure Sensor Serves Consumer Drone Needs
Booth 542 at Sensors Expo 2018. Bosch Sensortec has introduced a new high performance barometric pressure MEMS sensor. The BMP388 is ideally suited for altitude tracking in Consumer Electronics (CE) drones, wearables, smart homes and other applications. The BMP388 delivers outstanding altitude stabilization in drones, where accurate measurement of barometric pressure provides the essential altitude data for improving flight stability and landing accuracy. The new barometric pressure sensor is part of Bosch Sensortec's comprehensive sensor solution for drones, which includes the BMI088 Inertial Measurement Unit (IMU) for accurate steering and the BMM150 geomagnetic sensor for the provision of heading data.
The BMI088 is a 6-axis IMU, consisting of a triaxial 16-bit acceleration sensor with excellent performance and a triaxial automotive-proven 16-bit gyroscope. Drones can take full advantage of the IMU's superior vibration suppression and robustness and unmatched stability in dynamic conditions such as sudden temperature fluctuations. The BMM150 is a low power and low noise triaxial digital geomagnetic sensor designed for compass applications. Due to its stable performance over a wide temperature range, this geomagnetic sensor is especially suited for determining accurate headings for drones.
In addition to drones, the BMP388 provides a very flexible, one-size-fits-all solution for increasing the accuracy of navigation and fitness applications in wearables and smart homes, for example by utilizing altitude data to improve GPS precision or to determine floor levels inside buildings. It can also improve the precision of calorie counting in wearables and mobile devices, for example by identifying if a person is walking uphill or downhill when using a step counter.
