Creating the devices

I used 2 ESP8266-based nodemcu <a href="https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=nodemcu+devkit&safe=off&tbm=shop">devkits</a> as the microcontrollers/wifi connections. The code is <a href="https://github.com/wordsforthewise/esp8266-water-sensor">here</a>.
I measured water level with 2 wires and 2 resistors, following <a href="https://harizanov.com/2012/08/diy-soil-moisture-project/">this example</a>. I put the wires into a pvc pipe with holes drilled every foot. Then I connected the wires to the microcontroller, did some programming with the open source nodemcu firmware (writing in lua), and pushed and pulled the data to and from thingspeak, using another github library I wrote
