Sensors Are Everywhere!
Sensors Role in IoT• Sensors are the Eyes and Ears for the Internet of
Things• Provides a Way for Machines to Communicate
With People• Sensors Allow Knowledge Transfer to
Standardized Processes and Focus on Exceptions– People Can Handle the Outliers– Allow Companies to do Things Faster, Better
and with Fewer Resources• Sensors Provide Failure Alerting– Predicative Warnings with Data Mining
Success Wireless Sensor ChallengeLots of Moving Parts That All Must Line Up for Things to Work
Sensor Acquisition / Digitization Wireless Connectivity Storage Analytics Alerting Refinement
All Parts Need to Work Together
The Language of SensorsPercepts:• Digital (Off/On)– ESD– Level Switch (ie I’ve Reached this Level)
• Analog (Readings)– Tank Level– Pressure– Speed– Temperature
• GPS (Where am I)– LAT, LONG, Speed, Direction, Altitude
• Strings (Description)– Houston We Have a Problem
Obstacles to Overcome• Reading Resolution– Different Technologies Used Depending on Needed
Accuracy and Repeatability– Time for Reading / Number of Readings
• Environment– Sensors Need to Live in Harsh Environments• Electrical – Noise Affects Readings• Mechanical – Vibration, Temperature, Pressure• RF Interference – Shielding, Arcing
– Certification To Operate In Environment• Intrinsic Safety (C1D1, ATEX, IECEx)• Safety (UL, OSHA, CE)• Wireless (PTCRB, FCC, Carrier)
Obstacles to Overcome• Power (Line Power vs. Battery)– For Battery Devices Power Consumption is ALWAYS an Issue
– Wireless Communication is Expensive in Termsof Power Drain
• Report Time (How Much to Sleep vs. How Much Time Awake)– Can’t Communicate if the Device is Asleep– Best Way to Determine Issues Using Lowest
Amount of Power
Example: Tank Level Sensors• High Level Float Sensor– Digital On/Off
• Hydrostatic Pressure– Depends on Specific Gravity– Contact with Liquid
• Ultrasonic– Lower Cost, Gas Issues
• Float Level Sensor– Accurate; Installation Costs– Contact with Liquid
• Radar Level Sensor– High Cost
Sensor Trade-Offs• Technology– Distance (Ultrasonic, Radar, Magnetic)– Float (Switch, Magnetic, Resistive)– Pressure, Pneumatic, Magnorestrictive,
Capacitive, Radio, Radar• Chemical Properties of Target• Accuracy / Repeatability Required– Alarm (Digital, Analog)– Custody (Billing, Payment)
• Power / Infrastructure Needed– Battery, Solar, Line Power
• Interface– Digital, Analog, Modbus, HART
Wireless TechnologiesWhich Wireless Technology?• Satellite– Iridium, Inmarsat, Globalstar, Orbcomm
• Cellular– 3G – HSPA+/EVDO– LTE Cat 1/0/M– CIoT – Cellular IoT
• ISM / Proprietary– Short Range: BLE, 900 MHz, 802.15.4, ZigBee, Z-Wave,
6LoPAN, WirelessHART, ISA100.11a, ANT, EnOcean– Long Range: Semtech LoRa, Weightless, Freewave
Wireless Obstacles• Amount of Data (Size, Rate of Collection)– Increased Costs (Cellular, Satellite)– Increase Transmission Time (Bandwidth, Power)– Decreased Reliability (Retries, Power)
• Importance of Data – Not All Data is the Same– Dynamic Prioritization– Multiple Data Paths• Least Cost Routing
– Aggregation of Data• Compress over Time or Readings• Aggregate Multiple Sensors to Derive
Meaningful Results
Wireless Certification• FCC Part 15 / Industry Canada• GSM: PTCRB / GCF• CDMA: OTA• Carrier Dependent Safe For Network Testing• Country Specific Testing• LTE IoT• WiFi Alliance• BT Sig

Data Storage• 60% of Data Loses Value in Milliseconds of
Reading*• 90% of Data Never Acted Upon or Reviewed• Cloud Storage*– AT&T M2X, IBM Bluemix, nxCLOUDCONNECT
• Data Mining– Predictive Analysis for Failure
• Intelligent Alerting & Alarms– Ensure Correct Response to Event– Ensure Timely Response
* IBM IoT Paper
Big Data Analysis for M2M• M2M Sensor Data Measured in Big Data Terms Velocity: Real-time data to take action Volume: #Sensors X Update Rate X # Units Variety: Lots of repeating values or trending values• Looking over many units before failure can
identify patterns to predict failures.– Push Real-Time Analysis to Device in Field
• Analysis Needs to Be Continuous and Automated– AI Machine Learning
Security• Device Sensor Connections Unsecured• Many SCADA / M2M Systems Only
Basic Security in OS– Hardened Processors, TIA TR-50
• Each “Moving Part” Potential Security Opening
• Control Requires Higher Level Security• Cellular– LTE/GSM/CDMA Encryption– Private IP Spaces– Embedded SIMs
Evolution of M2M & Sensors
Transitioning Generations
GEN X/Y/Z
• Years of Experience• Hands On • Understand How It Works• If It’s Broke I’ll Fix It• Let Me Show You How This
Works
• Learning New Tasks• Automation is My Friend• Just Show Me• It’s Broke Who’s Going to
Fix It – Or Replace It• Just Send it to My Phone
Wireless Sensor M2M Trends• LTE Cat M Radios Drives Large Industry Adoption• One Long Range IoT Protocol Will Gain Marketshare• Equipment Selling with Wireless Cellular Monitoring– Pervasive Cellular Eliminates Point to Point Systems and
Satellite– Sensor Manufacturer Sells Data to Customer
• Data Aggregation and Analysis at Point of Collection• Sensor Subnets (Subnet of Things) – ISA100.11a, 6LoPAN, ZigBee– Totality of Sensor Data Identifies Common Trends
• No Consistency with Sensor Data Protocols– Carriers Provide Cloud Gateways to Normalize Data
What Does the Future Hold?• Standardized Configurations Allow Connections with ANY Machine/Sensor
• Wireless Connectivity Standard (Wireless HART)• Better Tools – Drag and Drop Configurators– Ad Hoc Reporting– GUI Widgets/Graphics for Quick Review
• Easy Installation– Better Way’s to Integrate With Current/Future Technology
• Automated Data Analysis Tools– Feedback to Remote Data Gateways
• For clients seeking cost-effective ways to optimize assets, ultrasonic sensors and GPS devices are necessary. By using a specific application that anyone can understand, this session will demonstrate how to simplify IoT monitoring complexities. Attendees will learn how to leverage M2M technology through sensor and wireless device, how to streamline operations and save money from wireless devices and sensors, and how M2M can track, monitor, manage, optimize & secure their assets remotely.
