Nan Values for the "hum" and "temp" Variables for Soil Sensor V2.2

I’m trying to use your esp-soil-moisture-sensor.ino sourced from here and when I serial print the following variables:

It prints the following lines:

Do note that if I do:

It prints values in the 900s which I can only assume are correct.

I have the Soil Sensor V2.2 board and have not adjusted the code, other than the two serial print lines. Do you know why this occurs and how I can fix it?

In addition, what do the values in the 900s mean? Is it a measurement of some sort of the humidity, for example water concentration and if so, what what is the unit of measurement?


Please try this sketch instead

Thanks. It worked. Greatly appreciate it!
