Creating the devices
I used 2 ESP8266-based nodemcu devkits as the microcontrollers/wifi connections. The code is here.
I measured water level with 2 wires and 2 resistors, following this example. 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: https://github.com/wordsforthewise/esp8266-send-thingspeak
