Soil Moisture sensor possible?

Hi there,

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

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

Provide a link to the spec for the module.

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

I'm currently working on an interface with this alternative sensor: http://wemakethings.net/chirp/

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.
