carbon dioxide detector

Another interesting use of the Arduino Lilypad... Diffus, a Danish design company, has created this beautifully crafted Climate Dress which monitors and responds to the amount of carbon dioxide in the air:

The Climate Dress is made of conductive embroidery, over hundred of tiny LED lights inserted into the embroidery, a CO2 sensor and an Arduino Lilypad microprocessor. The LEDs visualize the level of CO2 in the nearby surroundings and are powered trough the embroidery.

Just imagine this application on cycling apparel - LEDs pulsating based on the air conditions as you bike alongside city traffic. The more harmful, the faster the pulse...
