PT100 Sensor, 0-10V how to connect it to Arduino Due?

Other Hardware Sensors

Hello there,

i am very new to Arduino and elektronics, so this question might be trivial for many, maybe therefore i didnt find any easy solutions on the net.

I have a Arduino Due board and want to connect a (industrial) PT100 Sensor to one of the analog in ports. From the "transmitter" of the Sensor i already get a precise measurement voltage of 0-10V. The analog in port of the Due only accepts a Voltage range of 0-3.3V.
What is a good way to get a relatively cheap and accurate bridge here? I already thought of Step-Down Voltage-Controllers, but the ones i saw have a precision of about 4-10% and things get worse with changing input-voltages. I need a low budget and still precise (~1%) solution, can you help me please?

best regards

just a simple voltage divider will do. - google images "arduino voltage divider" is your friend :wink:

Ok, thank you :slight_smile:

and what can i use, to connect the 0-3.3V analog output of the arduino to an actuator that accepts control voltages from 0-10V? the same? sry but this will help me a lot..

and what can i use, to connect the 0-3.3V ANALOG OUTPUT of the arduino to an actuator that accepts control voltages from 0-10V?

Providing a PWM output from an Arduino on a OP-AMP will do the trick.

ok, thank you very much : )
