IoT Epoch Time Disaster? Only Time Will Tell

Ever heard of the “epoch time”? I’m not talking here about  history periods or geology. Epoch time is simply a standardized time and date reference used in UNIX and many other computers. It defines time, measured in seconds, starting from January 1, 1970 epoch. This is based on an arbitrary, somewhat historical epoch, but, what matters is that it is a commonly followed standard.

What is the anatomy of IoT sensor devices?

Executive Summary:

  • IoT Sensors include three fundamental functions: sensing, communication, and power supply, as well as additional functions: processing/system management and user interface
  • IoT application is determined by the types of sensors, cloud connectivity, power sources, and (optionally) user interface used in an IoT sensor device
  • It is possible to realize a variety of IoT applications with a single IoT sensor hardware platform by employing appropriate functional modularity and interface abstractions
  • An application processor and well defined interfaces help abstract functions for versatility and ease of use

Key considerations for IoT sensor devices: 4 – Security

Executive Summary:

  • Security is critical for IoT
  • End application defines security policy requirements
  • Security is weak if device crypto key are not well protected in IoT devices
  • Best-in-class security policies for IoT sensors are achieved with tamper-proof hardware crypto key management

Key considerations for IoT sensor devices: 1-Versatility

 

With my two decades of experience designing complex electronic systems as well as recent two years focused on building IoT systems and solving System Integrators’ pain points, several key characteristics became evident to me that define the best-in-class industrial IoT sensor devices:

  1. Versatility
  2. Power consumption efficiency
  3. Ease of use
  4. Security
  5. Industrial deployment readiness
  6. Cost effectiveness

Now, I will cover each consideration in more detail. More info

What are IoT sensor devices?

The previous article – “What Are IoT Sensors?” – gave a high level overview of IoT system, now let’s drill down to what are IoT sensor devices.

Executive Summary:

  • IoT sensors are necessary components of any IoT application
  • Consist of sensors combined with communication capabilities
  • Many different types of sensors exist
  • Wireless communication is key to new applications
  • Multiple wireless standards exist since no one size fits all
  • Need a way to abstract application from sensing and communication methods

What are IoT Sensors?

Internet of Things (IoT) is such an overloaded term that it can mean many things to many people or nothing at all.  The purpose of this series of articles is to explain what some of these popular terms mean in the context of the latest technologies. Then, I will segue into something much more valuable to learn about – the anatomy of (IoT) “things”, how they fit into the larger Industrial IoT landscape, and what are the key considerations for connected sensors (“things”), especially as they relate to industrial applications.
