CMOS image sensors have very much caught up to CCDs in image quality, have a significant power advantage and support higher frame rates. This might explain why CCD use in high-end digital SLRs will be moving from 12% today to 1% by 2014.
I'm not sure that CMOS has the big cost advantage that one might assume. CMOS image sensors aren't built in standard logic processes, where huge volume means low cost.
I totally agree, goafrit. It's another case of volume trumping quality as it is in other consumer electronics devices. Yet astronomy requires CCD quality: http://126.96.36.199:8080/CE2release/cesMain.jsp

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
