| Calculate and Plot Reading of a Water Well Sensor | |
| Simple software made for aiding in calculating the values that an analog voltage sensor will read from a series resistor | |
| in a water column height sensor with a constant current output. The analog sensor happened to provide its output value | |
| in percentage to the web API. | |
| Used for a particular setup where a Shelly 2PM + AddOn Plus was reading the voltage of the resistor. | |
