 My name is Kirby Atwater. I'm located in the Chicago area and one of the product marketing engineers for the mems and sensors technologies in North America What I'm going to talk about a little bit of some important points for about ST's mem sensors as it applies to wearable So when you consider the IOT wearable space ST is very well positioned to support the wide range of wearable technologies We have an extensive portfolio as well as our Bluetooth low-energy and sub gigahertz wireless technologies Together and offer a complete solution for sensing and communication portions of the wireless IOT applications and wearable applications Our men's motion sensors are capable of sensing simple motions Like a wake from sleep scenario, but also capable of sensing And making decisions based on multiple and complex movements or a series of moments and gestures Our environmental sensors are available to sense temperature pressure for maybe elevation sensing And then also relative humidity And all these capabilities are exceptional foundation for the development of some of the newer Tracking bands that have been requested by some governments to help with contract tracing for COVID-19 Having a Bluetooth low-energy radio and a very low power accelerometer Create a very efficient solution able to be powered by a coin cell or other small parts of the towards To evaluate and develop with our sensors and wireless components ST has developed a few different hardware tools and accompanying software tools to aid in the Evaluation both light and full-featured development processes that may be required by your engineering team So first we're going to take a look at the sensor tau dot box is a great example The sensor tau dot box is shown here is the little blue box with many different sensors both motion and environmental based as well as Bluetooth low-energy communication That works with our Android or iOS implementation of the ST BLE sensor app for your smartphone or tablet Both are available on the respective app stores on Google Play if you search for ST BLE sensor On either one of the app stores Let's take a further look at the sensor tau dot box and some of its internal So here we see the top of the PC board on the left the such how that box is powered by an STM32 L4 microcontroller Includes a grouping of environmental sensors As well as a Bluetooth low-energy 5 module for communicating to the ST BLE sensor app on your smartphone or tablet And then also a grouping of motion sensors in the upper left-hand corner Finally a micro USB port for direct connection for additional communications and also for advanced development capabilities that we'll talk about a little bit on the right side you see the Reverse side of the PC board the 500 milliampolithium polymer battery under that battery. There's a micro SD flash card slot With capabilities of supporting up to eight gigabytes of SD flash Which you can then use to store sample data for later processing after acquisition Finally, there's an ST V ST link v3 for directing bug connection to the STM32 L4 So let's take a let's take a little further look at the sensors on board If we take a look at the motion sensors first, we have the lsm6 ds0x It's a six axis accelerometer and gyro combo What we refer to as an IMU or international or inertial measurement unit This particular device has built-in finite state machine and machine learning core capabilities A little later on an in-depth discussion will on this functionality will be presented by one of my colleagues Additionally, there's two different three axis accelerometers the is3dh ultra low noise 2.5 g precision inclinometer and the li s2dw 12 ultra low power accelerometer And finally we have a three axis magnetometer the li s2 mdl For the environmental sensors in the middle, we have the lps 22 hh our absolute atmospheric pressure sensor the STTS 751 digital temperature Uh and the hts 221 relative humidity sensor along with the mp23 abs1 analog bottom port microphone Which has the capability of sensing into the ultrasonic frequencies to aid in predictive maintenance type applications I mentioned it's powered by the stm32 l4 r9 variant one of our most powerful devices We also have the blue energy m2 sx family with ble5 modules Rounding out the hardware is the stbco2 battery management ic for the lithium ion battery that you saw Just to highlight the bluetooth modules a little bit. There are two really two options the ultra low power or low cost variations based on both of them are based on the bluetooth 5 ic the blue energy 2 Running a cortex m0 at 24 with 256 k of flash and 24 k of ram Um Both of these are bluetooth 6 certified and have all the regulatory certifications for quick time to market for mass market customers Both come with an extensive peripheral set the i2c spi ur dma pdm inputs for our digital microphones just to name a few What differentiates the two the m2sa comes with a high efficiency chip antenna and its power consumption optimized With an internal switch mode power supply While the m2 spi is a cost optimized pc board with pc board trace antenna and an internal ldo oscillator instead When you use the stble sensor app for either android or ios This allows the engineer to utilize the such a tab box with various levels of development Uh, and in the case of entry mode that we're looking at here The customer can utilize pre-programmed applications that are stored in the app itself That can be downloaded and run on the central tab box And with the data then communicated back to the smartphone or tablet via the ble connection Some examples include the pedometer function simple vibration monitoring Leveling and inclination human activity recognition just to name a few there The next level above that is the what we call the expert working mode This is a mode that allows the user to define the applications by selecting the desired sensors and creating functions directly from the mobile app The expert mode allows the user to adjust the parameters of each of the sensors For example, maybe the full scale the output data rate, uh, and and various filtering The customer can build this application In the working mode without writing a single line of code. That's a nice feature with this And finally we have what we call the pro working mode This mode is fully compatible with our stm32 od environment targeting professional level of development In this case the user is able to write custom firmware based on the stm32 cube hardware abstraction layers Middleware and some of the various examples included Many of the examples are available in source code level to provide a great reference when starting a new design Next we'll take a look at the algal builder application that you can run on your pc Algal builder is a pc-based graphical user interface and development environment Especially designed for the ease of evaluation In develop of software that you're going to embed into the microcontroller that will either manage one or multiple sensors Depending on what your desired application is The tool allows the customer to create a like a block diagram or a flow chart of the signal coming from a particular sensors You know from the inputs the processing path that Make consists of filters or embedded libraries and other functions And then the output signals as they may be desired this again Done completely without the engineering having to write any code of their own The tool is fully compatible with our stm32 ide and visualization tools For viewing the performance of the algorithm that's generated. So This this shows a graphical kind of how it all integrates together The algal builder works very well with a central tile dot box It's one of the best tools to fully utilize the central tile dot box capabilities The tool allows the customer to take pre-compiled code libraries His firmware template and the code designed in the algal builder itself Combine them into a firmware project That you can use with either the stm32 cube ide compiler I'll mention it's a no-cost compiler tool set for the customer or if the customer has ir kyle They have a seed of one of those they can use that also It's just the compiler the debugger and the programming tools are all linked into algal builder There's no need for the outside the customer to go outside of the development environment to develop compile And test the algorithms once the central tile dot box has been programmed The the the unico GUI interface can be called from the algal builder To visualize the application as is desired The algal builder the stm32 cube ide central tile dot box Along with the capabilities of the stble sensor tool for your smartphone Making for a very versatile development tool chain for sts many different sensors
