xTendLoRa mesh-capable LoRa data radio Supports AT commands & MODBUS

Posted on by Tope Oluyemi

A Crowdfund campaign is set to be launched soon for the XTendLoRa, which is a mesh-capable LoRa data radio with support for AT commands & MODBUS.

“Whether you are designing an Internet of Things (IoT) product, constructing a smart home, rolling out a sensor network, developing a building automation solution, or just trying to make your machines talk to one another (and to their SCADA overlords), xTendLoRa will help you avoid many of the usual pitfalls. And if your project has to contend with RF noise, large metal objects, and extreme temperatures, xTendLoRa is likely one of the only affordable wireless mesh technologies capable of getting the job done.”

Operating over the 915 MHz, license-free Industrial, Scientific and Medical (ISM) bands, the xTendLoRa capitalizes on the spread-spectrum modulation of LoRa to derive reliable, long-range, high-sensitivity communication—over a multi-hop mesh—even when faced with significant RF or physical interference. You can use basic AT commands or a MODBUS register map to configure and control its complete wireless mesh stack. This combination of simplicity and flexibility is important to reducing development and deployment times for projects that depend on robust communication in harsh environments.

The device features a multi-hop mesh stack and RS485 serial interface. It enables simple AT commands, compatible with a MODBUS Remote Terminal Unit (RTU) profile, and has Good interference immunity. Repeater functionality is field configuration via IO pin. Devices can be allocated to different virtual networks, and it offers Unicast, multicast, and broadcast messaging. It also offers a flexible sink node setting for gateway Device and enables device Firmware Upgrade (DFU) over UART. The device is hardware competent for OTA, and supports 915 MHz ISM-band operation, 4.5 v to 30 V operating volt, and operation temperature from -20° C to 85° C. It has a fixable output power up to +17 dBm, with receiver sensitivity down to -12dBm at SF 8. Finally, it enables AES- 128 CBC packet encryption, and MUI – 64 modem identity

xTendLoRa’s modem—which, thanks to its RS485 interface, can talk to any device with a serial port—will arrive factory-provisioned for guaranteed out-of-the-box connectivity but with full support for custom configurations. For now, there is not much information about the device, so we do not know when the campaign will kickoff, but hopefully very soon. There is also no information about the price, but we will surely get information when the campaign goes live.   You can visit crowd supply’s page to sign up for information about when the campaign will go live.

Panasonic introduces polymer tantalum solid capacitors

Posted on by mixos

Panasonic Industry Europe introduces the new TPS series, a surface mount Conductive Polymer Tantalum Solid capacitor series. The POSCAP TPS series capacitors feature sintered tantalum as an anode and highly conductive polymer as the cathode.

TPS series also has a compact design of only 3.5×2.8.x1.1mm and a high-temperature rating of 105°C for up to 2.000 hours. The new capacitors benefit from a rated voltage of 2.5 to 6,3V and a low ESR (Equivalent Series Resistance) of only 30mΩ. The capacitance range is rated from 150 up to 330µF.

The very compact TPS series capacitors aim to ensure optimal quality and reliability that renders them ideal for demanding applications like placement close to the processor (CPU) of a notebook or a very compact desktop PC, for example at the rear side of a PCB or under the heat sink.

Also, IoT applications or wearables can benefit from the features of the new POSCAP TPS series by Panasonic Industry Europe.

ATmega328-Based Smartwatch Keeps Track Of Drugs In Your System by Analyzing Your Sweat

Posted on by Tope Oluyemi

Wearables have been part of the medical field for a while now, making the work of medical practitioners easier. They help monitor heart rate, temperature, oxygen levels etc. However, to achieve the mission of personalized medicine, centering on delivering the right drug to the right patient at the right dose, therapeutic drug monitoring solutions are necessary. This has moved engineers from the UCLA Samueli School of Engineering and the Stanford School of Medicine to develop a smartwatch capable of tracking a wearer’s metabolization of medicines, by analyzing their sweat. About the smartwatch, Assistant Professor Sam Emaminejad who is the study lead says :

“We wanted to create a wearable technology that can track the profile of medication inside the body continuously and non-invasively…This way, we can tailor the optimal dosage and timing of the intake for each individual. And using this personalization approach, we can improve the efficacy of the therapeutic treatments.”

 

voltammetric sensing interface

The engineers devised a surface engineering strategy, which enabled them to create a voltammetric sensing interface, featuring an “undistorted potential window,” within which the target electroactive drug’s voltammetric response is dominant and interference is eliminated, rendering reliable target quantification in noninvasively retrievable biofluids (sweat and saliva).

“Leveraging this sensing interface, a fully integrated, wearable solution was constructed to seamlessly render drug readouts with minute-level temporal resolution. To inform its clinical utility, the solution was utilized to demonstrate noninvasive pharmacokinetic monitoring of a pharmaceutical (here, acetaminophen, a widely used analgesic and antipyretic) in a wearable format.”

The smartwatch features an on-board LCD panel for live monitoring and a Bluetooth connection that transmits to an external data capture system for later analysis. At the core of the smartwatch is a Microchip ATmega328-based microcontroller which is connected to a 16-bit Texas Instrument DAC8552 digital-to-analog converter. It also features a Linear Technology LT1462 transfer impedance amplifier, a TI 12-bit ADS1015 analog-to-digital converter, and a Wurth Electronik AMB2621 Bluetooth module for communication. The smartwatch takes advantage of the small molecular structure of many drugs, which enables them to be present in our sweat. This enables the device to analyze the drug due to the quantities found in the sweat, and also detect how much of the drug is still circulating in the wearer’s system. The engineers carried out the test of the watch by tracking acetaminophen (an over-the-counter painkiller) over a short period, using a small electric current to force the wearer to sweat under the sensor.

About the smart watch, co-author Professor Ronald W. Davis says:

“This technology is a game-changer and a significant step forward for realizing personalized medicine.” He continues “Emerging pharmacogenomic solutions, which allow us to select drugs based on the genetic makeup of individuals, have already shown to be useful in improving the efficacy of treatments. So, in combination with our wearable solution, which helps us to optimize the drug dosages for each individual, we can now truly personalize our approaches to pharmacotherapy.”

Optically Isolated Bidirectional I2C Shield For Arduino

Optically isolator Arduino Shield has been designed to provide optically isolated I2C communication between Arduino and any other device or sensors that works with I2C protocols. I have used the ISO1540 Low-Power Bidirectional I2C Isolator IC from Texas Instruments to build this project, and the device is compatible with I2C interfaces. These devices have logic input and output buffers that are separated by Texas Instruments Capacitive Isolation technology using a silicon dioxide (SiO2) barrier. When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging the Arduino board. The ISO1540 has two isolated bidirectional channels for clock and data lines. The project is suitable for multi-master applications. For applications where clock stretching by the slave is possible. LED D1 is the power indicator for side two. This board requires two separate supplies, side one powered from Arduino UNO 5V, side 2 require separate 3.3V to 5V.

Features

  • Isolated bidirectional, I2C compatible, communication
  • Supports up to 1-MHz operation
  • 3-V to 5.5-V supply range, Side 1 Connected to Arduino Uno 5V Supply
  • Side 2 Supply 3.3V to 5.5V DC
  • Open-drain outputs with 3.5-mA Side 1 and 35- mA Side 2 sink current capability

The I2C bus is used in a wide range of applications because it is simple to use. The bus consists of a two-wire communication bus that supports bidirectional data transfer between a master device and several slave devices. The master, or processor, controls the bus, specifically the serial clock (SCL) line. Data is transferred between the master and slave through a serial data (SDA) line. This data can be transferred in four speeds: standard mode (0 to 100 kbps), fast mode (0 to 400 kbps), fast-mode plus (0 to 1 Mbps), and high-speed mode (0 to 3.4 Mbps). The most common speeds are the standard and fast modes. The I2C bus operates in bidirectional, half-duplex mode, while standard digital isolators are unidirectional devices. To make efficient use of one technology supporting the other, external circuitry is required that separates the bidirectional bus into two unidirectional signal paths without introducing significant propagation delay. These devices have their logic input and output buffers separated by TI’s capacitive isolation technology using a silicon dioxide (SiO2) barrier. When used in conjunction with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.

Adjustable Constant Current LASER Diode/LED driver

Posted on by mixos

I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and should have some sort of constant current circuit as a basic protection for the laser diode. As a result, I built this circuit which provides highly accurate current control.  The module is a great tool to drive low-cost laser diodes with superb accuracy. This circuit can drive diode starting from 0 mA to 115mA, usually, these cheap diodes require around 30mA current. The project has an onboard multi-turn potentiometer to adjust the output current with great accuracy. It is advisable to turn the trim-pot to zero level and then hook-up the laser diode.
