[Solved] Problem with AH3503 hall sensor

hi

i have ah3503 hall sensor uno in analog0 , doing simple read.

when doing nothing have reading around 635-638, sounds ok. when place metal in front of or magnet, goes 2-3, highest have seen 641.

i have connected this



and code

code: [select]

void setup()
{
  serial.begin(9600);
}

void measurement()
{
int raw = analogread(0);   // range : 0..1024

serial.print("output: ");
serial.println(raw);
}

void loop()
{
    delay(1000);
    measurement();
}

can't more simple think. doing wrong , shouldn't higher reading no matter put in front of it?

can post link datasheet of sensor?

635 seems around 3v

if remove 10k resistor do?
