Temperature Sensors

Temperature sensors output a voltage that is linearly proportional to the Celsius (centigrade) temperature. In this program we will be referring to a readily available TMP36 sensor

The below table list the key elements of a number of common temperature sensors available.

Temperature Calculation (TMP36)

The above graph shows a linear relationship between output voltage and temperature.

  • The TMP36 sensor will output 0.5V at 0°C
  • There is a 10mV change per degree of change in temperature (°C)
Temperature (°C) = (Output Voltage - 0.5)*100
