ActiviTea – physical data-scraping in action

Posted on Monday, October 8th, 2012 in Arduino, sensors by the machinegeek

The crew from Imagination Labs wanted to track the number of cups of tea consumed at their office. They designed Activitea, a project incorporating a series of sensors placed throughout the London Imagination office that count the cups of hot drinks made in every kitchen.

“The prototype consists of 3 objects:
1. A ‘tea counter’ object housing an ultrasonic sensor.
2. A receiving/transmitting object, housing an Arduino and a digital transmitter module.
3. An optional solar power object (housing four solar cells), which produces enough power to support the project.”

The ultrasonic sensor senses the presence of a cup, which is then logged by the Arduino and submitted to an online database. Cumulative consumption data can be viewed here.
