240V light usage logger
Exhibitor: Luke Billingham
Supervisor: Geoffrey Walker
Research Group: Embedded Systems
Industry Sector: Energy and Utilities
With the increasing popularity of compact fluorescent lamps being used to replace normal incandescent lamps in households, a proposal to Energy Australia was submitted to re-lamp households in Sydney with compact fluorescent lamps. To support the case of power saving, a 240V Light Usage logger is needed.
The number of times a light is switched ON and OFF and how long it is on for affects the lifetime of the lamp. To support the claim of power saving and longer lamp lifetime, a Light Usage Logger is needed.
The Light Usage Logger logs the number of hours runtime and the number of ON/OFF switches and stores them in EEPROM. There are a total of 128 different time blocks available, each allowing up to 4 billion ON/OFF switches.
The light usage data is sent via infrared to a PDA and then can be uploaded later to a database on a PC where it can be correlated and analysed.
