Chapter 5. Making an XBee Smart Power Switch
In this chapter, we will build a remotely controlled smart power switch. This switch will be a do-it-yourself version of the power switches that you can find in many stores. We will be able to switch a device on and off and also measure the current consumption of the connected device. As the LabVIEW LINX interface for Arduino only supports serial-based communication at the time of writing this book, we will use XBee to communicate wirelessly with the project.
We will first connect the required components to our Arduino board: a relay module, a current sensor, and an XBee shield. Then, we will write a LabVIEW program to control the relay module and measure the current consumption of the connected device. ...
