Sensors are where rubber meets the road in the Internet of Things, and a tour of the show floor at the Sensors Expo in San Jose, California showed that road has many, many lanes.

The event attracted dozens of vendors showing product portfolios packing a variety of technologies to address a wide range of markets. A few common themes emerged.

Sensors are becoming more integrated with hybrid sensors a clear trend. Prices are falling as smartphones drive volume sales.

While several big companies play here, so do many, many small and medium ones scattered geographically across regions little known for high tech. The much-hyped IoT has generated a lot of buzz and new design activity but hasn’t yet spawned significantly more business for companies who have served this broad collection of embedded markets for many years.

Come along as I tour about a third of the show floor collecting snippets of stories about sensors. Take a tour of the Sensors Expo 2016 in the gallery.
