Use Temp Sensor TMP36 with Arduino

In this tutorial you will learn how to use the TMP36 sensor with Arduino uno. The room temperature will be printed to serial monitor. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn’t require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. We like it because it’s so easy to use: Just give the device a ground and 2.7 to 5.5 VDC and read the voltage on the Vout pin. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C.

Wiring Instructions

To wire your TMP36 to your Arduino, connect the following pins:

  • Connect the 5V pin to 5 Volts (5V)
  • Connect the SIGNAL pin to analog pin 0
  • Connect the GND pin to ground (GND)

Recommended Software
