How Much is your Desk Lamp Costing per Year?

Presentation: 1:00-3:00 p.m., Kennedy Union Torch Lounge



Growing electricity bills plague many of us who call Dayton home, but what exactly can we do to combat those rising prices. The most simple solution is to crack down on turning off lights when they are not in use. In this experiment I will explore the cost of a desk lamp that is used semi-frequently throughout the week and explore the amount of electrical energy it consumes on a daily basis. Basic cost of electricity will be set as the rate at which the electrical company, AES, charges my house per kilowatt hour. The data will be recorded via an Elegoo Uno R3 microcontroller with a photoresistor connected to measure when the light is turned on and how intense the light is. The data collected will then be used to draw conclusions about the cost to operate a single lamp per day, per month and per year.
