# Water Usage Monitoring

> Monitor your water usage using a ThingySticks Water Monitor over your network with a WIZNet WIZ750SR.

## Components

- **WIZnet WIZ750SR** x 1 ([docs](https://docs.wiznet.io/Product/S2E-Module/WIZ750SR/))

## Article

As is typical during the debugging phase of the project I used the serial port a lot to output the sensor data and read user instructions. This is where the WIZNet WIZ750SR really shines, by simply connecting the Feather Rx/Tx/GND pins to the WIZ750SR's Tx/Rx/GND pins I was able to send normal serial data to a network connection, as well as receive values sent back, The 3v3 pin of the Feather is used to power the WIZNet module.

I 3D-printed an enclosure to hold the ThingySticks water monitor and the WIZNet module, bolted the POE Splitter on to the case lid and connected it all up.
