Fast and Cost-Effective Evaluation of the Mass Flow Meters SFM3xxx-AW and SFM3xxx-D

Posted on by mixos

Sensirion, the worldwide leading manufacturer of high-quality flow and environmental sensors, is launching a new evaluation kit. With the EK-F3x-CAP, expiratory and proximal sensors of the SFM3xxx platform can be tested quickly and easily. The evaluation kit works with both the disposable and reusable variants of the flow sensors.

The EK-F3x-CAP evaluation kit offers a simple and cost-effective way to test sensors of the SFM3xxx platform. The set consists of a USB cable which connects to the corresponding flow meters. Using the software available online, the sensors can be quickly tested under real-life conditions. There is no need to program a microprocessor as the evaluation kit can be directly connected to a PC. The software shows the measurement data directly on the user’s computer screen. Furthermore, the data can be exported into an Excel spreadsheet which can then easily be saved and further processed.

The Sensirion SFM3xxx platform includes sensors for inspiratory, expiratory and proximal flow measurement, as well as gas mixing in ventilation and anesthesia applications. With the platform, the sensor manufacturer offers its customers the right sensor for all flow measurements and underscores its worldwide expertise in the field of medical ventilation. The reusable “AW” versions are autoclavable and washable, and therefore well-suited for expiratory flow measurement. The disposable “D” versions are a safe and cost-effective alternative to reprocessing.

Like all sensors from Sensirion, the outstanding performance of the SFM3xxx sensors is based on the patented CMOSens® Technology. This enables integration of the sensor and evaluation circuit on a single CMOS silicon chip. The result is an ultra-precision system that offers long-term stability for sophisticated and cost-sensitive applications. The technology is also highly resistant to environmental effects, which is why Sensirion’s flow sensors are perfect for use as sterilizable sensors.

Visit Sensirion between February 5 and 7, 2019 in Anaheim at the MD&M West fair, stand 1556, and learn more about the new evaluation kit EK-F3x-CAP.

Osram enables projections with the smartphone

Posted on by mixos

Laser technology from Osram transforms smartphones into beamers.

Green lasers for projector applications need to have not only outstanding beam characteristics but also a high optical performance in order to deliver sharp and bright images. Although a projector also needs red and blue lasers, green is the crucial color in RGB solutions – and also the color that poses the greatest challenges in production. PLT3 520D continues Osram’s success story with green lasers. At 140 mW it achieves an unprecedented high pulse output for direct green laser diodes. In addition, the efficiency of the laser has been increased to a typical value of 8%. Thanks to these improvements, it is now possible to turn a smartphone into a small cinema projector. The small display of the device can be enlarged several times over.

In addition to playing smartphone videos on a flat surface, RGB laser projection can be used, for example, for large-scale projection of holiday memories.

Up to now, RGB laser projections for smartphones, based on a red, green and blue laser, often had brightness problems. The reason was the often insufficient brightness of the green laser. Green light has a special importance in RGB applications because the human eye is most sensitive in the green spectral range. The brighter the green laser shines on a surface, the brighter and stronger the projected image appears to the viewer. With its PLT3 520D now offering 140 mW at 300 mA in pulsed mode (50% duty cycle), Osram has achieved unprecedented performance for a green single-mode laser. So far, the limit for these components was 80 mW. A further advantage of the diode is its compact and space-saving TO38 metal housing with a diameter of only 3.8 mm. The laser diode with a wavelength of 520 nm has been specially developed for laser projection applications that use a MEMS scanner as the image encoder.

“Thanks to OSRAM’s long tradition and expertise in the laser sector, we have succeeded in driving forward developments in this key technology,” explained Pedro Muñoz, Marketing Manager at Osram Opto Semiconductors. “Based on our quality promise, users can be confident that this technology will open up additional functions on smartphones in the medium term.”

Tektronix AFG31000 – Arbitrary Function Generators

Posted on by mixos

The AFG31000 Arbitrary Function Generator from Tektronix is designed for the demanding performance expectations throughout the product realisation process. The instrument incorporates a 9-inch capacitive touch display and a shallow menu tree that make locating and changing settings quicker, whilst also making browsing easier.

The AFG31000 series sports a 9-inch capacitive touchscreen that allows users to zoom in on areas of a waveform in unprecedented detail. All related settings and parameters can be viewed on a single screen via a shallow menu tree. An intuitive user interface allows users to tap or swipe to browse, locate, select and edit settings, cutting the time required to learn and operate the AFG.

The AFG31000 series debuts a new patented feature known as InstaView, designed to eliminate impedance mismatch problems. Conventional AFGs assume they are driving a 50Ω impedance, but few devices under test (DUTs) actually have that impedance, leading to inconsistencies between the waveform set on the AFG and the signal at the DUT.

InstaView addresses this problem by monitoring the waveform at the DUT on the AFG, allowing waveform verification without the need for additional cables or instruments. The waveform display responds to changes in frequency, amplitude, waveform shape and DUT impedance in real time. Alongside conventional AFG operating modes, the AFG31000 series provides an ‘Advanced’ mode that allows programmable waveform sequencing.

In Advanced mode, the AFGs up to 128 Mpts of waveform memory can be segmented into up to 256 entries. Users can drag and drop long waveforms, or multiple waveforms, within the sequencer and define how they are output. For engineers requiring long non-repeating waveforms, or multiple waveforms with complex timing, the AFG31000 series offers a significantly more affordable alternative to expensive arbitrary waveform generators (AWGs).

Key settings are visible at a glance, and are easy to adjust using touch, numeric keypad, or rotary controls

Another new feature built into the AFG31000 series is the ArbBuilder tool, which lets users create and edit arbitrary waveforms directly on the AFG, using templates and an equation editor, rather than having to create them on a PC and transfer them over.

Key performance specifications

  • 1 or 2 channel models
  • Output amplitude range 1 mVP-P to 10 VP-P into 50 Ω loads
  • Basic (AFG) mode:
    • 25 MHz, 50 MHz, 100 MHz, 150 MHz, or 250 MHz sine waveforms
    • 250 MSa/s, 1 GSa/s or 2 GSa/s sample rates
    • 14-bit vertical resolution
    • Built-in waveforms include sine, square, ramp, pulse, noise, and other frequently used waveforms
    • Sweep, Burst, and Modulation modes (AM, FM, PM, FSK, and PWM)
  • Advanced (Sequence) mode:
    • Continuous mode (optional Sequence, Triggered and Gated modes)
    • 16 Mpts arbitrary waveform memory on each channel (128 Mpts optional)
    • Up to 256 steps in sequence mode with loop, jump and wait events
    • Variable sampling clock 1 µSa/s to 2 GSa/s

Key features

  • Patented InstaView™ technology enables engineers to see the actual waveform at the Device Under Test (DUT) in real time, without the need of an oscilloscope and probe, eliminating the uncertainty caused by mismatched impedance
  • Sequencing option adds the ability to program long, complex waveforms with up to 256 steps
  • The 9-inch capacitive touch screen works like a smart phone and has short-cuts to frequently used settings
  • Built-in ArbBuilder lets you create and edit arbitrary waveforms on the instrument, eliminating the need to connect to a PC
  • Outputs are protected from over voltage and current to minimize potential instrument damage
  • Compatible with TekBench™ software to help students set up, control, and analyze test results in the lab

Alternatively, waveforms captured by an oscilloscope can be saved as .csv files and loaded directly into the AFG using ArbBuilder.

The new Tektronix AFG31000 series Arbitrary Benerators start from €1,930. More information: www.tek.com

TTGO T-Camera is an ESP32 CAM Board With OLED and AI Capabilities.

Posted on by Ayo Ayibiowu

Just like Arduino, ESP32 has been one of the boards that have found love among hackers and makers around the world. Unlike general Arduino boards, ESP32 offers much more at a fraction of the cost and most importantly are usually compatible with Arduino based code.

Recently we have seen the rising of ESP32 in the areas of Artificial Intelligence especially those focused on Computer Vision (Mostly around Face Detection and Recognition) such as the camera boards ESP32-CAM and the upcoming ESP-EYE board from Espressif Systems. The ESP EYE as mentioned before is an AI development board based on the ESP32 and capable of some vision and voice capabilities.

One significant note about the ESP CAM and the ESP EYE is the lack of any display medium aside from the use of LEDs or using an external interface like the computer or mobile phone, in this regard is where the TTGO T-Camera board comes in. The TTGO T-Camera hopes to solve the supposed visualization problem, by integrating a 128 x 64 OLED display which can be used to display your detection, sensor, recognition, and other kinds of data. Of course, don’t expect to be able to view face image on the OLED display!

TTGO T-Camera Board
TTGO T-Camera ESP32 Camera Board With OLED

The TTGO T-Camera is basically a combination of the ESP CAM, the ESP EYE, and an OLED display. It doesn’t end there, and it also includes a BME280 environmental sensor for sensing temperature, humidity, and pressure. Also, you got a PIR sensor for motion sensing and an optional fisheye lens for the camera.

Application of the TTGO T-Camera is limited by the user, and some potential application will be using the inbuilt PIR sensor of the device to detect motion in a doorway, room or somewhere and only capture the image when someone is present. Face detection and recognition can be done for possible access control or in case of security, hook the device to the internet and upload the image of the potential intruder to an online server. Basically, think about all the features of the ESP32 CAM and some features of the ESP EYE boards.

Getting Started with STM32G0

Posted on by mixos

The STM32G0 is ST’s newest series of mainstream microcontrollers (MCU) for cost-oriented consumer and industrial applications. [via]

This new generation offers an Arm® Cortex®-M0+ core at 64 MHz as well as a Securable Memory Area, more RAM and Flash, numerous I/Os, and more hardware modules, such as a USB-C controller, to simplify significantly the overall PCB design.

The new STM32G0 Series is not simply another Cortex-M0+ microcontroller. It sets a new definition of what an efficient microcontroller must offer. This is all about being optimized, in each and every detail, to offer the best value for your money and allow you to achieve your goals with the minimum BOM cost and the maximum flexibility for upgrades.

We named our new series STM32G0 because it builds on the foundations of the STM32F0. However, instead of using its 180 nm process node, it relies on a 90 nm node similar to the STM32L4. Using this new lithographic method enabled us to benefit from some of the ultra-low-power capabilities of the L4, while also integrating more components and optimizing the architecture to push the performance and features of the F0 to an entirely new level.

  • The STM32G0x0 Value line is highly competitive in traditional 8-bit and 16-bit markets and embeds an accurate internal clock allowing further cost saving. It eliminates the need to manage different architectures and the associated development overhead.
  • The STM32G0x1 line provides upgraded features in analog and is IoT ready with upgraded security functions. It offers a wide range of memory sizes, voltage, and packages, bringing flexibility to cost-sensitive applications.
