Ethical and Environmental Considerations in Smart Home Technology Development

This document outlines the environmental and ethical challenges associated with the manufacturing and lifecycle of smart home technologies. It emphasizes the need for an industry-wide shift away from hazardous materials used in PCB and IC production, particularly with components like ZigBit. The text addresses energy efficiency targets, including compliance with One Watt Initiative and EU regulations, and the importance of utilizing RoHS components. Additionally, it discusses the ethical implications of choosing manufacturers, safety concerns of dimmer and IR modules, and the potential for promoting slothfulness through automation.

  1. Home Kinection Brian Bowman, Reid Erekson, Stephen Larew, Will McGrath,

  2. Environmental Lifecycle Analysis • Product Manufacture • PCB and IC production w/ hazardous chemicals • Unavoidable without industry wide shift • Plastics used in SSR and casing • Due to choice of ZigBit, no control over its production. • Use RoHS components.

  3. Stage: Normal Use • Standby power: • Approximately 100 mW • Could be reduced with radio sleep mode • Meets objectives of One Watt Initiative and E.U. E.C. Regulation 1275/2008 • USB and shade module PSU > 90% efficiency • Other PSUs could be made > 90% efficient • ISM spectrum crowding • HomeKinection for a “smart” home

  4. Stage: Disposal • Usual electronic waste issues • Small, distributed modules • Requires effort to collect and dispose • Conceivably tens to hundreds of modules per house • Use RoHS • Attach labels to each module describing proper disposal methods

  5. Ethical Concerns • Increased spotlight on manufacturing ethics • See Foxconn “sweatshop” issues • Could/should choose an ethical manufacturer? • Other business ethical considerations

  6. Safety Ethics • Dimmer module • Only compatible with incandescent lights • Safely integrate with variety of lights? • e.g. plug type, warning labels • IR module • Avoid increasing volume out of control • Test overheating of module in A/V cabinet

  7. Safety Ethics • Shade module • Very simple and incapable of damage • Health of indoor occupants (lack of sunlight) • USB HID • Could the device short or over-load USB port? • Command module • Overheating • Custom case and power solution • What happens when communications link down?

  8. Safety Ethics • System view • Does our system promote slothfulness? • One step closer to Wall-E type future? • Wireless spectrum limited • Failures in system communication • Should lights stay on or turn off upon failure? • Could USB HID run “rm –rf /” (or equivalent) • Should there be authorized users?

  9. Questions?
