Let's get started by installing the proper firmware on our three XBee modules. We want to setup the XBee firmware the same way as in the XBee Basics Lesson 4 video except this time setup two routers instead of one. Be sure to use the same PAN ID for each. Once you have the proper firmware on the XBees let's put the hardware together as shown in the below figure.
|Hardware setup for capturing temperature data from multiple XBees|
|The two routers each with a temperature sensor|
|XBee coordinator, temperature sensor, and Arduino Uno|
//the following line calculates voltage, then temperature, and then prints temp to serial monitor
//this function calculates temp in F from temp sensor
|Serial monitor displaying data from each temperature sensor|
Well that is it for part 2. Normally I would share the list of parts you need for the next part of the project, but in part 3 and part 4 we will look at multiple options for powering the sensors in the project so read it first and then decide what works best for powering your temperature sensor network. If you have any questions on part 2 use the comment area below or feel free to email your question to me at firstname.lastname@example.org. Stay tuned for part 3!
