ST’s MEMS & Sensors: Shaping the future of IoT

Sensors are shaping business and lifestyles worldwide and they can offer better results and more significant energy savings when they become a lot smarter

STEVAL
STEVAL-MKSBOX1V1 (SensorTile.box) multi sensor development kit

ST offers the widest range of MEMS and Sensors covering a full spectrum of applications from low-power devices for IoT and battery-operated applications to high-end devices for accurate navigation and positioning, Industry 4.0, augmented virtual reality components and smartphones.

During their annual media briefing, Vishal Goyal, Senior Technical Marketing Manager, Analog and MEMS Group, RF, Sensors and Analog Custom Products, Asean-ANZ and India, STMicroelectronics shares an interactive notion with BIS.

Here Is What We Found Out about ST’s focus into Machine Learning and Finite State machine enabled sensors, Vibration and sound fusion, Sensor based algorithm generation tool, Ready-to-use box kit with wireless IoT and sensor.

SensorTile.box:

  •          The STEVAL-MKSBOX1V1 (SensorTile.box) is a ready-to-use box kit with wireless IoT and wearable sensor platform to help you use and develop apps based on remote motion and environmental sensor data, regardless of your level of expertise.
  •          The SensorTile.box board fits into a small plastic box with a long-life rechargeable battery, and the ST BLE Sensor app on your smartphone connects via Bluetooth to the board and allows you to immediately begin using the wide range of default IoT and wearable sensor applications.
    In Expert Mode, you can build customs apps from your selection of SensorTile.box sensors, operating parameters, data and output types, and special functions and algorithms available. This multi sensor kit therefore allows you to design wireless IoT and wearable sensor applications quickly and easily, without performing any programming.

         SensorTile.box includes a firmware programming and debugging interface that allows professional developers to engage in more complex firmware code development using the STM32 Open Development Environment (STM32 ODE), which includes a sensing AI function pack with neural network libraries.

Key Features
o Easy-to-use app with immediate functionality for the following motion and environmental sensor applications:
– Pedometer optimized for belt positioning
– Barometer / environmental monitoring
– Vehicle / goods tracking
– Vibration monitoring
– Compass and inclinometer
– Sensor data logger
o Expert Mode with additional sensor app parameter settings
o Compact board with the following high precision sensors:
Digital temperature sensor (STTS751)
– 6-axis inertial measurement unit (LSM6DSOX)
– 3-axis accelerometers (LIS2DW12 and LIS3DHH)
– 3-axis magnetometer (LIS2MDL)
– Altimeter / pressure sensor (LPS22HH)
– Microphone / audio sensor (MP23ABS1)
– Humidity sensor (HTS221)
o Ultra-low-power ARM Cortex-M4 microcontroller with DSP and FPU (STM32L4R9)
o Bluetooth Smart connectivity v4.2 (SPBTLE-1S)
o Programming and debugging interface for professional firmware development

AlgoBuilder

o A new version of the AlgoBuilder (v 2.2.0) is available with a NEW Feature that allows you to send data to the cloud (AWS), run your application, perform machine learning computation, everything in cloud. It is one of the most important features for Industry 4.0 and is called the AWS connectivity.
o AlgoBuilder is an application for graphical design of algorithms. It quickly elaborates prototypes of applications for STM32 microcontrollers and MEMS sensors, including already existing algorithms (e.g. sensor fusion or pedometer), user-defined data processing blocks and additional functionalities.
o The application eases the process of implementing proof of concept using a graphical interface without writing the code. AlgoBuilder reuses previously defined blocks, combines multiple functionalities in a single project and visualizes data using Unicleo-GUI in real time using plot and display.

AlgoBuilder utilizes the STM32 ODE (Open Development Environment) ecosystem which combines hardware like STM32 Nucleo boards (NUCLEO-F401RE or NUCLEO-L476RG), X-NUCLEO-IKS01A2 or X-NUCLEO-IKS01A3 expansion board and software (STM32 HAL drivers, BSP structure, low and high-level sensor drivers) and Unicleo-GUI.

Key Features

  Simple graphical design of algorithms (drag and drop, connect, set properties, build, upload)

  Optional multi-level design

  Wide range of function blocks available in libraries, including motion sensor algorithms (sensor fusion, gyroscope, magnetometer calibration and pedometer, for example)

  Integrated function blocks for FFT analysis

  Function block creator for custom block creation

  Automatic validation of design rules

  C code generation from the graphical design

  Use of external compilers (System Workbench for STM32, IAR EWARM, Keil µVision®)

  Generated firmware output displayed through integrated output data monitor or Unicleo-GUI

  Open XML format for function blocks and design storage

  Possibility to send output data to AWS cloud using MQTT protocol

  Support for NUCLEO-F401RE or NUCLEO-L476RG with connected X-NUCLEO-IKS01A2 or X-NUCLEO-IKS01A3 expansion board and SensorTile STEVAL-STLKT01V1 and SensorTile.box STEVAL-MKSBOX1V1

  Network updates with automatic notification of new releases

  Free user-friendly licensing terms

Unico GUI

  •          Designed for use with our ready-to-use MEMS motherboard (STEVAL-MKI109V3), this multi-platform GUI lets you easily set up sensors, configure registers and explore advanced features.
  •          Unico interacts with all the MEMS demonstration boards supported by the STEVAL-MKI109V3 (Professional MEMS tool) motherboard and allows a quick and easy setup of the sensors, as well as the complete configuration of all the registers and the advanced features embedded in the digital output devices. The software visualizes the output of the sensors in both graphical and numeric format and allows the user to save or generally manage data coming from the device.
  •          The UNICO-GUI STSW-MKI109 series package is available for three different platforms
  •       Key Features

– Complete software package for MEMS evaluation boards

       Programmable voltage power supply between 1.8 to 3.6 V

       Sensors current consumption measurement

       Communication protocol SPI/I2C selectable on the fly

       Graphical User Interface (GUI) for:

o  Linux (Debian-based) platforms

o  Mac OS X platforms

o   Windows platforms

       Device firmware upgrade application (DfuSe)

Among the major attractions included the LSM6DSOX iNEMO sensor which comprises:

  •         A machine-learning core to classify motion data based on known patterns. Relieving this first stage of activity tracking from the main processor saves energy and accelerates motion-based apps such as fitness logging, wellness monitoring, personal navigation, and fall detection.

“Machine learning is already used for fast and efficient pattern recognition in social media, financial modelling, or autonomous driving,” said Andrea Onetti, Analog, MEMS and Sensors Group Vice President, STMicroelectronics. “The LSM6DSOX motion sensor integrates machine-learning capabilities to enhance activity tracking in smartphones and wearables.”

All-round this year ST’s annual media briefing demonstrated the company’s leadership in the growing MEMS and Sensors technology.
