<br> [return to sensor page](./../Sensors.html) ###Analog Temperature sensor. MCP9700.  Here is a three-legged part that gives an analog voltage that is a linear function of temperature. Provide 3-6 volts to the left leg (see photo), ground the right, and measure the signal from the middle leg.   [MCP9700 Datasheet](http://ww1.microchip.com/downloads/en/DeviceDoc/20001942G.pdf) From the datasheet. The graph shows the relation between output voltage and temperature.
