Netduino analog input?


I’m planning on buying a Grove Moisture sensor for my netduino but I have a problem: … 3d51f.html

This sensor has an analog output from 0 to 5 Volts, but Netduino analog inputs only allow 0 to 3.3 Volt input.

¿Has anybody faced this problem before?

¿Could anybody give me some schematics or point me in the right direction?

Thank you!

Well, it’s not an issue exclusive of the moisture sensor.

It affects every analog sensor that is connected to netduino analog pins. When voltage rises over 3.3 volts, analog reads become garbage.

I would need something in between the sensors and the grove shield so the output of the sensor is corrected from 0-5 to 0.33
