This is the same temperature sensor that is included in our SparkFun Inventor’s Kit. 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 Â±1Â°C at +25Â°C and Â±2Â°C over the âÂˆ´40Â°C to +125Â°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/Â°C.
