1) Introduction

Measuring temperature is a popular way to get started with analog sensing. This example uses the TMP36 low-voltage linear temperature sensor that is included in the XBee Wi-Fi Cloud Kit. The TMP36 is very easy to set up. It doesnt require any complicated circuits or tricky calculations to determine if its hot or not.The sensor generates a voltage output output that is directly proportional to the Celsius temperature. The hotter it is, the higher the voltage that is passed to the XBees analog-to-digital converter (ADC). This reading is then sent via Device Cloud to the XBee Wi-Fi Cloud Kits online dashboard application where you can monitor the temperature right in your web browser.

2) Assemble the Parts

To hook up a temperature sensor youll need:

• 1 - XBee Wi-Fi Cloud Kit*
• 1 - TMP36 - for sensing temperature (data sheet)
• 4 - 10K ohm resistors
• Jumper wires
