Temperature Sensor – TMP36, PTH, TO-92
This easy to use 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.
Simply give the device a ground, a 2.7 to 5.5 VDC, and then read the voltage on the Vout pin. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C.
This device is perfect for use in Environmental control systems, Thermal protection, Industrial process control, Fire alarms, Power system monitors and CPU thermal management etc…

These sensors are cheap, easy to use and give accurate feedback. They’re fine on the Arduino, but they can’t be used on the Raspberry Pi without adding a MCP3008 (or equivalent) analogue-to-digital convertor.
