Grove Moisture Sensor with Raspberry Pi

Purchased Grove Moisture Sensor.

It looks like it will NOT connect directly to Pi’s GPIO pins directly, but will need Grove Pi Plus.

Is that correct?

Wouldn’t it need a A/D module?

Hi there,

yes, the raspberry pi does not have the adc function. you can add grove-adc module to convert the analog signal to i2c signal. but we do not have the python library yet. you also can google MCP3008 chip. there are python library for this chip. thanks.
