What's the real hold up?

Loring, you mention competing standards as one impediment holding back the adoption of  wireless sensor networks. If the economic case is getting stronger, what are the stumbling blocks around deployment given that the applications seem pretty compelling?

Probably the biggest problem in universal adoption is that there is no single protocol that is the equivalent of 802 LANs and the seven-layer OSI prototol stack in wireless sensor nets.  ZigBee is the most common physical and data-link protocol, though there's a lot of RFID, Wireless HART, NFC, etc.  Eventually, probably all such nets will use TCP/IP and have an IP address.  But the IP connection is not obvious because the cost of nodes needs to be so low.  Until the cost of microcontroller-powered "dust" drops, we may have quite a protocol mess out there!

Loring: In the RFID world, we used tto hear about "nickel tags." The belief was that when nickel tags arrived, millions of products would suddenly use RFID. Is there a similar price-point goal for microcontroller-powered dust?

Chuck, I hear different numbers all the time, but I think people expect a fairly functional (8-bit?  16/32?  ADC?) microcontroller available in high volume for well under $1, say in the 30 to 50 cent range.  Whether the low end is feasible....

Loring, I agree that one of the main things holding back widespread use is the competing standards.  When I worked for an OEM, the customers always had some other idea in mind (and a lot of times it was whatever was "hot" at the moment".

I still think the other issue is the power source.  Once battery technology evolves to where you can get a reliable long-term (i.e., year+) or self-recharging source, this tech will really take off.

Thanks for bringing up the battery issue, Jack - absolutely critical.

There are lithium batteries that have non-rechargeable operating lives of 25 years. They are already used in wireless devices such as utility meters and wireless sensors by the millions.

Thanks.  I'll look into that....  (At the moment, it doesn't look like the website is working).

Many attempts have been made and are underway for implementing energy harvesting systems for powering the low power wireless sensor networks. It will be really interesting to explore a bit on these systems too

Latest Analysis
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
US factory orders for durable goods tumbled 3.4% in December on a big drop in new bookings for commercial aircraft, according to data the Commerce Department released Tuesday.
