TC74A0-5.0VAT

/*
The TC74A0-5.0VAT is a digital temperature sensor that communicates over the I2C interface. Here's an example code in Arduino that reads the temperature from the sensor:

Note: This code assumes that the TC74A0-5.0VAT temperature sensor is connected to the I2C interface of the Arduino board. The I2C address of the sensor is set to 0x4D, but you should verify the address using a scanner tool if you're unsure. Also, note that the sensor requires a warm-up time of at least 30ms after power-on before providing accurate readings, so be sure to wait for this period before reading from the sensor. Finally, note that the temperature readings are in Celsius (°C).

#include <Wire.h>

const byte ADDRESS = 0x4D; // the I2C address of the sensor
int temperature;  // the temperature reading from the sensor

void setup() {
  Serial.begin(9600);
  Wire.begin(); // start the I2C interface
}

void loop() {
  Wire.beginTransmission(ADDRESS);
  Wire.write(0x00); // select the temperature register
  Wire.endTransmission();

  Wire.requestFrom(ADDRESS, 1); // request 1 byte of data
  if (Wire.available() == 1) {
    byte msb = Wire.read();
    temperature = msb; // convert the byte to temperature
    Serial.print("Temperature: ");
    Serial.print(temperature);
    Serial.println(" °C");
  }

  // delay before reading from the sensor again
  delay(1000);
