I want to connect a soil moisture sensor to my esp8266 to monitor the plants



Is this possible with the nodeMCU firmware? Can anyone help with some sample code on how to read this kind of sensor with nodeMCU?

Most likely u can, depending if it is digital or analogue... That will affect its implementation.

Unlike most of the others it is capacitive, so less chance of it degrading over time.

It just outputs the capacitance over i2c so it's easy to use.

Oh, plus it's all open source so you can hack away at it and look at the schematic, code etc.
