This project is to use a wifi microcontroller in promiscuous mode to sniff all mac addresses and their signal level. It will also have an onboard temperature and humidity sensor. This is to track where a person is in the house based off of their phone signal. Since there is one of these modules in each room, capturing the temperature and humidity is added as well.
The latest design will use my RS485 PCB with the RTL8720DN BW16 module. This will allow me to track both 2.4Ghz and 5Ghz WiFi. The RS485 will act as a backhaul so i don't have to capture, connect, publish, diconnect, repeat like the first design. This will allow for greater capture time and shorter capture intervals. It will also allow a syncing of the capture accross all of the sniffers.
The latest design will also use the HDC1080 for its temperature and humidity since that is more accurate and more reliable than the DHT22
