“We’ve seen recent growth in Internet of Things (IoT) applications using the Google Maps Geolocation API instead of GPS for asset tracking, theft prevention, usage optimization, asset servicing, and more,” said Ken Nevarez, Industry Solutions Lead at Google. “As part of my 20 percent project at Industry Solutions, I created a prototype IoT device that can locate itself using surrounding WiFi networks and the Google Maps Geolocation API. In this post, I’ll discuss some interesting implementation features and outline how you can create the prototype yourself.”
Nevarez says he “built a device that scans for local WiFi and writes results (WiFi hotspots and their signal strength) to a Firebase Realtime Database. A back-end service then reads this data and uses the Google Maps Geolocation API to turn this into a real-world location, which can be plotted on a map.”
Here is Navarez’ description to creating an efficient geo-aware product:
Set up the Device & Write Locally
For this proof of concept, I used the Intel Edison as a Linux-based computing platform and augmented it withSparkfun’s Edison Blocks. To build the device, you will need an Intel Edison, a Base Block, a Battery Block and a Hardware pack.
