Sensors from the M2M world are evolving into connected sensors for IoT. Same sensor tech but now the sensor needs to communicate outside of a local and often proprietary network. Goodbye 35 year-old Modbus, used in SCADA of yesteryear and hello layered communication, needed in the Internet of Things to onboard billions of sensors. In this episode of the IoT Inc Business Show, Mike Fahrion explains not only the anatomy of today’s connected sensor, but also why we’re moving to a layered communication stack.
Mike is the director of product management at B&B Electronics and the company’s Internet of Things strategist. He is an expert in data communications, with 20 years of design and application experience at the “edge” of networks in remote, harsh or uncontrolled environments. Mike is a speaker and author and has a newsletter, eConnections, which has over 50,000 monthly subscribers.
Silo’d communication of the M2M age doesn’t scale. Abstracting communication into 3 layers: the media layer (the physical hardware – wired and wireless), the communication layer (the way the data is organized before being sent) and the application layer (raw data augmented with meta or semantic information,) simplifies and scales the usage of IoT data by separating how the data was produced from how it is consumed – just like today’s internet apps.
