Features

  • Analog Temperature Output: Produces an output voltage proportional to temperature.
  • Calibrated in Degrees Celsius: Temperature can be calculated directly from the output voltage.
  • Low-Voltage Operation: Operates from a supply voltage of 2.7V to 5.5V.
  • Low Power Consumption: Suitable for battery-powered and low-power electronic systems.
  • Microcontroller Compatible: Can be read using an analog input on compatible Arduino boards and other microcontrollers.

Principle of Operation

TMP36 With Arduino Temperature Sensor Code & Tutorial

The TMP36 provides an output voltage with a nominal scale factor of 10mV/°C and an offset of 500mV at 0°C. Temperature can be estimated from the output voltage using: Temperature (°C) = (Vout − 0.5) × 100 Here, Vout is measured in volts. For example, an output of 0.75V corresponds to approximately 25°C.

Applications

  • Ambient temperature monitoring
  • Arduino and microcontroller projects
  • Environmental monitoring systems
  • Temperature-controlled fans and alarms
  • Educational electronics and prototyping
  • Battery-powered temperature measurement devices

Pinout

TMP36] Temperature Sensor | circuitholic

For the standard 3-pin TO-92 package, with the flat face toward you and the leads pointing downward:

  • Pin 1 (Left): +Vs — supply voltage
  • Pin 2 (Middle): Vout — analog temperature output
  • Pin 3 (Right): GND — ground

Confirm the pin arrangement against the manufacturer's datasheet for the supplied package.

Wiring

  • Connect +Vs to a compatible 3.3V or 5V supply.
  • Connect Vout to an analog input, such as Arduino A0.
  • Connect GND to the controller's ground.

Simple Arduino Code

 const int sensorPin = A0;
  void setup()
  { Serial.begin(9600); 
  } 
void loop() { int reading = analogRead(sensorPin);
 float voltage = reading * (5.0 / 1023.0); float temperatureC = (voltage - 0.5) * 100.0; 
Serial.print("Temperature: "); 
Serial.print(temperatureC);
 Serial.println(" °C");
 delay(1000);
 }

This example assumes a 5V Arduino with a 10-bit ADC and a 5.0V reference. Adjust the voltage calculation for your board's ADC resolution and actual reference voltage.
