  1. Class 1: Home Automation Basics Prototyping Home Automation Concepts December 12, 2016 - Don Wilcher

  2. Home Automation Basics Topics • State of Home Automation • Example Systems and Devices • Hands-On Project: Pushbutton Switch and Buzzer, GrovePi+ Introduction

  3. The State of Home Automation • By 2022, a typical family home could contain more than 500 smart devices. • A rise in the level of excitement about the smart home: a) millennials (79%) b) parents (76%) c) 50% of the overall population excited about the technology Source: Icontrol State of the Smart Home 2015 report.

  4. The State of Home Automation… • Home monitoring cameras and connected door locks are the among the most popular devices consider. a) a burglary takes place every 14.1 second in the US b) break-ins are through the front or back doors • Heating and cooling accounting for 48% of energy use in a typical home: • Thermostats topped the list of the most popular products in 2015. Source: Icontrol State of the Smart Home 2015 report.

  5. Question 1 What population group has the highest percentage rating based on smart home excitement?

  6. Example Systems and Devices Wink Relay • A touch screen control panel • Install it in place of a standard light switch • Create a common center for a variety of smart products

  7. Question 2 Name the two most popular devices considered for smart homes.

  8. Example Systems and Devices… Wink Relay • Works with third party experiences like Uber, FitBit, and IFTTT(If This Then That)

  9. Example Systems and Devices… Schlage Deadbolt Locks

  10. Question 3 The Wink Relay can be considered as _______ for home automation. • an electromechanical switching device • a common center for a variety of smart products • a smartphone • None of the above

  11. Example Systems and Devices… Nest Thermostat

  12. Example Systems and Devices… Apple Homekit

  13. Example Systems and Devices… Chamberlain Garage Door Opener

  14. Example Systems and Devices… AT&T Digital Life

  15. Hands-On Project: GrovePi+: Pushbutton Switch and Buzzer-Alarm

  16. Hands-On Project GrovePi+: Pushbutton Switch and Buzzer-Alarm Project Objectives: • Learn about the GrovePi+ Shield Architecture a) Review of the circuit schematic diagram b) Review of electrical connectors and ports • Build a pushbutton switch actuated buzzer-alarm

  17. Hands-On Project… GrovePi+ Shield: Partial Circuit Schematic
