Reading IR Thermistor

Hello,

I wired my sensor according to this diagram:

and here’s my sketch:

void setup() {
  // put your setup code here, to run once:

pinMode(A5,INPUT);

  Serial.begin(9600);

}

void loop() {
  // put your main code here, to run repeatedly:
Serial.println(analogRead(A5));


delay(100);
}

and when I wave my hand in front of the sensor, the values aren’t budging.
Any help would be appreciated

What is an "IR Thermistor"?

The diagram shows what could be a Melexis non-contact IR thermometer, which is a digital device.

Find out what you actually have, and use Google to find code for it.

That's not how you read an i2c sensor. Read about it here.
