This is the same temperature sensor that is included in the 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 1C at +25C and 2C over the 40C to +125C 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.
- Voltage Input: 2.7 V to 5.5 VDC
- 10 mV/C scale factor
- 2C accuracy over temperature
- 0.5C linearity
