Tiny Battery Powered Tracker with Wifi Sniffing
We have been asked numerous times for a device that can be used for indoor tracking to locate items where even the best GPS will not work – such as in a warehouse or basement.
This version of the Yabby uses a unique wifi positioning system (WPS), or WiFi sniffer, to scan for WiFi access points and the signal strength from each one. This information is then used to triangulate a position which is typically accurate to 100 feet / 30m in metropolitan areas. And this can all be done in typically less than 3 seconds, using a lot less power than a typical GPS fix.
This wifi positioning system, combined with the new low power capabilities of the LTE-CATM1 module allows us to shrink the design size down even smaller and use smaller AAA batteries.
