WiFi Sniffer + Temperature Humidity

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

The first design uses the generic DHT22 + ESP8266-01 modules that can be found cheaply on ebay/aliexpress. 

I designed a 3d printed case for these modules and it can be found here https://www.thingiverse.com/thing:4390142
