Capacitive Soil Sensor Integration #195

Closed NathanWilcox closed 5 years ago

NathanWilcox commented 5 years ago

Describe the problem you have/What new integration you would like

Please can you look into integrating a Soil Capacitance Moisture Sensor such as: https://www.banggood.com/5pcs-Capacitive-Soil-Moisture-Sensor-Not-Easy-To-Corrode-Wide-Voltage-Module-For-Arduino-p-1326816.html?rmmds=myorder&cur_warehouse=UK

Please describe your use case for this integration and alternatives you've tried:

I have looked at similar requests for soil moisture sensors but they are not the same as these capacitance sensors. I have also looked for voltage to moisture conversion as stated in other posts but I cannot locate such information on the docs website.

Additional context

Nah this is also an analog sensor. From the page:

A miniature PC such as the Raspberry Pi only needs an external ADC (analog to digital signal) conversion module to work.

See the AVOUT pin for getting the data.
