Visitor Tracking via WiFi -2

details

WizFi310 captured the probe request packet of the WiFi terminal and proceeded to save it to the SD card it is already done previously. So link is http://wiznetmuseum.com/portfolio-items/visitor-tracking-via-wi-fi/

Components:

WIZwiki-W7500ECO’s Ethernet
WizFi310
MQTT Broker
Raspberry PI

In this post, Next proceeded to a project to store MAC information of nearby WiFi terminals on a cloud server (MQTT Broker) using WIZwiki-W7500ECO’s Ethernet, not SD card.

The MQTT Broker to use is https://io.adafruit.com .

The topic to use when publishing to the broker was used as the MAC of the device, and the message was taken as the RSSI value. (ex: topic: jehoon / f / 0008dc123456, message: 80)

In doing so, it is possible to know the existence of a certain WiFi device in the vicinity of WizFi310, the approximate stay time, and the like.

First, after running the MQTT broker on Raspberry PI, I checked to see if MQTT Publish is working properly.

Since then io.adafruit.com saw to try to Publish Broker, adafruit Broker is a topic people tried to remove and then re-Publish: ” In the MAC and then verify that Publish does not contain any “.”

Here are some of the things we learned from the project and analyzing the data:

You can see if a specific device is around the WizFi310. The graph below compares the two devices. The left device was a long way from WizFi310 during the morning hours and came in the afternoon.

On the right side of the graph, the device was not scanned during lunchtime in a certain pattern.
