WiFi Water Tank Level Meter Arduino software v1.0

Use the following board file in the Arduino IDE (under Tools -> Boards):
"WeMos D1 R2 & Mini"

If that is not available in the list of options, go to Arduino IDE File ->
Preferences and add the following to Additional Board Manager URLs:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Then go to the Board Manager and install the ESP8266 package.


Important notes:

1) Since publication, the software has been modified to support two WiFi networks,
   primary and secondary. Secondary is used if primary is not available/working.
   If you only have one WiFi network, set the SSID and Key values to the same
   for both.
2) You can change the INTERVAL_SECONDS value near the top of the file to log data
   more or less often (default: 10 minutes or 600 seconds). Note that power
   consumption increases if you reduce this value.
