Soil Moisture sensor with Arduino board

I have soil moisture sensor with four pins:
Signal +
Signal -

Output of the sensor is 0-1100mV

I don't know how to use it with Arduino. Please help me.

Where is the link to the data sheet for your sensor? That will tell you what Vcc is and other parameters apply to the device.

Hi, @anon83617181
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

This will help with advice on how to present your code and problems.

Thanks.. Tom... :grinning: :+1: :coffee: :australia:

Data Sheet URL

Thank you Tom

Ok, that is a good start.
That tells me you need to supply the device with a voltage of 9 - 18 volts for power.
That tells me you need to supply some kind of trigger to get a response from the device.
That tells me you need to amplify the output signal before your Arduino can do much with it.
But some other data sheet, somewhere, must have more information.
