Tech stocks have been volatile lately, but there are a number of new secular trends which investors are looking to remain exposed to in the long-term. Of these, easily the most exciting for certain semiconductor companies, gadget makers, and telecom firms is the Internet of Things.

For those that don’t know, the Internet of Things is the growing world of interconnected household and industrial devices. Everyday products and machines can now be embedded with sensor technology to process data or interact with other electronic devices.

For example, consumer-level IoT products include things like Amazon’s (AMZN) Echo “smart speaker,” wearable motion and activity tracking products, and advanced in-car technology. On the commercial side of the IoT market, industrial manufacturers have begun implementing sensors into machines to track performance and efficiency.
