You may be interested in this new module from G2 released just last week. It’s the most power efficient, and fully integrated Wifi device available. It’s almost everything you need to build a tag or data collection device except interconnects, sensors, a battery and housing, with all the certifications done. At $22 in quantity, this will set the price of tags competitively.
They’ve also released some software that allows you to collect the data from the tags for telemetry applications. Seems all we need are some minor tag engineering and an application front-end. Anyone have a compelling, yet unaddressed application? Perhaps I’ll take it on…..
