TECHNOLOGY IN A CONNECTED WORLD

IoT Gateway Advances Take Diverse Paths: Flexible Networked Solutions
The Internet-of-Things (IoT) phenomenon offers huge opportunities. Circuit Cellar Chief Editor Jeff Child explores how IoT gateways play a vital role in those systems by providing Nov 328 coverbidirectional communication between the devices in the field and the cloud.

Power Analysis Attack on RSA: Asymmetric Adventures
Colin O’Flynn has done a number of great columns about cryptography—in particular symmetric cryptography. This time he’s tackling an asymmetric algorithm: a RSA implementation. Colin describes what’s unique about an RSA cryptosystem and takes us through a power analysis attack.

FOCUS ON ANALOG

Analog Solutions Fuel Industrial System Needs: Connectivity, Control and IIoT
Whether it’s connecting with analog sensors or driving actuators, analog ICs play many critical roles in industrial applications. Here, Circuit Cellar Chief Editor Jeff Child examines the latest analog technologies and products serving the needs of today’s industrial systems.

Using Power Audio Amplifiers in Untypical Ways (Part 2): More Alternative Uses
In Part 1 Petre Petrov described many interesting ways to use power audio amplifiers (PAAs) as universal building blocks similar to the op amps and comparators. Here, he discusses several more things that can be built from PAAs including wave generators and transformer drivers.

SPOTLIGHT ON MONITORING AND TESTING

Gas Monitoring and Sensing (Part 2): Putting the Sensor to Work
Columnist Jeff Bachiochi continues his exploration of gas monitoring and sensing. This time he discusses some of the inexpensive sensors available that can be applied to this application. Jeff then tackles the factors to consider when calibrating these sensors and how to use them effectively.

Logger Device Tracks Amp Hours (Part 2): Alternative Energy Sources
n this follow on to Part 1 of his story, William Wachsmann describes putting to use the amp-hour logger he built using a microcontroller and a clamp-on ammeter. This time he discusses modifying the amp-hour software so it can be used as an analog input logger to measure solar and wind power.

Negative Feedback in Electronics: A Look at the Opposite Side
Complementing his discussion last month on positive feedback, columnist George Novacek now takes a look at negative feedback. Just like positive feedback, negative feedback can significantly change or modify a circuit’s performance.

LF Quartz Resonator Tester: A Stimulating Discussion
Ed Nisley returns to the rich topic of low-frequency quartz resonators. This time he describes a tester built with an ordinary Arduino Nano and an assortment of inexpensive RF modules.

INTERESTING EMBEDDED PROJECTS

Simulating a Hammond Tonewheel Organ (Part 1) Mimicking a Mechanical Marvel
Hammond tonewheel organs were based upon additive sine-wave synthesis. Because of that, it’s possible to simulate the organ using a microcontroller program that feeds its output waveform to a DAC. Brian Millier takes on this project, making use of an ARM-based Teensy module to do the heavy lifting.

Machine Auto-Sorts Resistors: MCUs, Measurement and Motor Control
Typical electronics lab benches become littered with resistors from past projects. These three Cornell University graduates tackled this problem by building a resistor sorting system. It enables users to input multiple resistors, measure their resistance and sort them. The project integrates motor controllers, resistance measurement and a graphical user interface.

Arduino Board Pair Boasts LoRa and GSM Capabilities

Arduino has introduced a pair of new Internet-of-Things (IoT)  boards with embedded LoRa and GSM capabilities. The boards were first unveiled at World Maker Faire New York. The Arduino MKR WAN 1300 and MKR GSM 1400 enable system developers to quickly add connectivity to their projects and ease the development of battery-powered IoT edge applications. Both of the highly compact boards measure just 67.64 mm x 25 mm, together with low power consumption, making them an ideal choice for emerging battery-powered IoT edge devices in the MKR form factor. Suitable applications examples include environmental monitoring, tracking, agriculture, energy monitoring and home automation.

Arduino DKb9irAW4AAM320-1Offering 32-bit computational power similar to the Arduino MKR ZERO board, the MKR WAN 1300 is based around the Murata LoRa low-power connectivity module and the Microchip SAM D21 microcontroller, which integrates an ARM Cortex-M0+ processor, 256 KB Flash memory and 3 2KB SRAM. The board’s design includes the ability to be powered by either two 1.5 V AA or AAA batteries or an external 5 V input via the USB interface—with automatic switching between the two power sources.

In addition, the MKR WAN 1300 offers the usual rich set of I/O interfaces expected with an Arduino board, and ease of use via the Arduino IDE software environment for code development and programming. Other features  include an operating voltage of 3.3 V; eight digital I/Os; 12 PWM outputs; and UART, SPI and I2C interfaces.

Like the MKR WAN 1300, the Arduino MKR GSM 1400 is based on the SAM D21, but integrates a u-blox module for global 3G communications. The board features automatic power switching, however, it uses either a 3.7 V LiPo battery or an external Vin power source delivering 5 V to 12 V. While the USB port can also be used to supply 5 V to the board, the MKR GSM 1400 is able to run with or without the battery connected.

The MKR GSM 1400 provides a rich set of I/O interfaces including: eight digital I/Os; 12 PWM outputs; UART, SPI and I2C interfaces; analog I/O including seven inputs and one output; and eight external interrupt pins. Both boards are now available for pre-order on the Arduino Store.

Gas Monitoring and Sensing (Part 1)

Fun with Fragrant Analysis

Gas sensing technology has come long way since the days of canaries in coal mines. This month columnist Jeff covers the background issues surrounding gas monitoring and sensing. Then he describes how he uses sensors, A/D conversion and Arduino technologies to do oxygen measurement.

By Jeff Bachiochi

When coal miners began dropping like flies, it was determined that poisonous gas was the culprit. To date there was no test to detect the presence of this odorless ghost. Sacrificial canaries became the guinea pigs, giving up their lives to save the miners. These birds are especially sensitive to methane and carbon monoxide. When the song bird stopped singing, miners headed for a breath of fresh air until the mine could be cleared of the silent killer.

Seemingly ripe for disaster, the flame height of an oil lamp was used for detecting dangerous conditions in the 1800s. A shrinking flame indicated reduced oxygen, while a stronger flame indicated the presence of methane—or other combustible gas. Flame arrestors kept the combustion internal to the lamp, preventing external gas ignition unless it was dropped.

In the 1900s, it was discovered that the current through an electric heater was affected when nearby combustible gases increased in temperature. The use of a catalytic material—such as palladium—lowers the temperature at which combustion takes place. Using these heaters in a Whetstone bridge configuration—where one leg is exposed to the gas—can create an easily measured imbalance proportional to the concentration of the combustible gas.

Infrared light can be used to measure the concentration of many hydrocarbon gases. When compared to a gas-free path, the IR absorption through a gas can indicate the concentration of hydrocarbon molecules. Gases can be identified by their molecular makeup. That is the amount of each element present. Absorption bands can be identified by dispersion through diffraction or non-dispersion through filtration. Concentration is the relationship of a particular wavelength between a reference path and a gas absorption path.

This summary of the basic gas sensing methods includes their advantages, disadvantages and general areas of use. (Source: www.equipcoservices.com/support/reference/ionization-potentials-of-common-chemicals),

There are many techniques available today for monitoring gases. Refer to Table 1 for a breakdown of gas monitoring methods and their associated advantages and disadvantages. HAZMAT Class 2 in United States identifies all gases which can be compressed and stored for transportation. Even though we are not directly dealing with storage or transportation, the class is further defined by three groups of gases: flammable, toxic and others (non-flammable).
