• ±0.5°C linearity (typ)
• Stable with large capacitive loads
• Specified −40°C to +125°C, operation to +150°C
• Less than 50 µA quiescent current
• Shutdown current 0.5 µA max
• Low self-heating
• Qualified for automotive applications

Here's a basic tutorial on how to connect and use a TMP36 Temperature Sensor with an Arduino, along with some sample code:

Step 1: Hardware Connection

Connect the TMP36 Temperature Sensor to your Arduino board as follows:

• VCC to 5V
• GND to GND
• VOUT to an analog input pin on Arduino (e.g., A0)

Step 2: Upload the Example Code

Here's an example code that reads and displays the temperature data from the TMP36 Temperature Sensor:

const int tempPin = A0; // Pin number of the temperature sensor

void setup() {
  Serial.begin(9600); // Initialize Serial communication
}

void loop() {
  int sensorValue = analogRead(tempPin); // Read analog value from sensor
  float voltage = sensorValue * (5.0 / 1023.0); // Convert to voltage (0-5V)
  float temperatureC = (voltage - 0.5) * 100; // Convert to Celsius
  float temperatureF = (temperatureC * 9 / 5) + 32; // Convert to Fahrenheit

  Serial.print("Temperature (C): ");
  Serial.print(temperatureC);
  Serial.print(" °C, Temperature (F): ");
  Serial.print(temperatureF);
  Serial.println(" °F");
  delay(1000); // Delay for stability
}

Note: Please make sure you have connected the TMP36 Temperature Sensor to the appropriate pin on your Arduino board, as per the tutorial instructions. Also, the TMP36 Temperature Sensor provides analog voltage output that needs to be converted to temperature using the appropriate formula. In this example, we have used the default formula for the TMP36 sensor, but you may need to adjust it depending on the specific TMP36 module you are using or the temperature unit (Celsius or Fahrenheit) you want to display. Additionally, make sure to handle the sensor with care, as it may become hot during operation.
