Smart Wearable and IFTTT

In Chapter 6, Smart Wearable, we looked at how to build a simple wearable that displays a user's location and also reads accelerometer values. In this chapter, we are going to take that application to the next level by implementing fall detection logic on the device and then adding If This Then That (IFTTT) rules on top of the data to execute actions when certain events happen. We will look at the following topics:

• What is IFTTT
• IFTTT and IoT
• Understanding fall detection
• Accelerometer-based fall detection
• Building an IFTTT rules engine
