Measuring magnetic fields with Arduino

Hello,

Your application interests me but I do not understand how you made the connection between Arduino and Geogebra. If I vary A0 from 0 to 5V and I send serial port information :

Arduino soft :

#define PinAna 0 //

int val;

void setup() {

Serial.begin(9600);

}

void loop () {

val = analogRead(PinAna);

Serial.println(val);

delay(250);

}

On geogebra I want to move a point A (0, val) vertically with val the value read on the serial port. What script should you write and where should you write it?

Thank you

Thanks for a nice clear write-up.

In your photo, it looks like you are powering the PmodCMPS with 5v, but the datasheet states maximum 3.6v.

Can you confirm that you are feeding it 5v ?

I did the same thing, but am getting no I2C response and suspect I fried my sensor.

Very enjoyable post. This looks like something I will want to look into. Can the Arduino be used as a Geiger counter?

Very good post.

I wonder how sensitive the sensor is to magnetic fields?

What is the response time to get a good measurement?

Can it detect transient events?

Thanks
