Day 4 Arduino Advent Calendar

Arduino Advent Calendar Day 04 - Temperature Sensor

Yesterday you measured light, today it's time to feel the heat (or at least measure it) with a temperature sensor. 

Public Service Announcement

 

We are going to use a TMP36 Temperature Sensor. In an ironic twist, this temperature sensor, if hooked up incorrectly will heat up so hot that it can burn your fingers! Let's make sure you hook it up correctly!



Meet the TMP36! 

The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. We like it because it’s so easy to use: All we need to do is give the TMP36 5 Volts from our Arduino and then read the sensor readings on the voltage output pin.

Let's build up the circuit over at guides.littlebird.com.au .
