Pigeons Get Backpacks for Air Pollution Monitoring
LONDON -- A flock of pigeons fitted with mobile phone backpacks is to be used to monitor air pollution, New Scientist magazine reported on Wednesday.
The 20 pigeons will be released into the skies over San Jose, California, in August.
Text messages on air quality will be beamed back in real time to a special pigeon "blog," a journal accessible on the Internet.
Miniature cameras slung around the pigeons' necks will also post aerial pictures.
The idea is the brainchild of researcher Beatriz da Costa, of the University of California at Irvine, and two of her students.
They have built a prototype of the pigeons' equipment, containing a mobile phone circuit board with SIM card and communication chips, a GPS receiver, and sensors capable of detecting carbon monoxide and nitrogen dioxide.
"We are combining an air pollution sensor with a home-made cellphone," da Costa told New Scientist.
The team is planning to squeeze all the components onto a single board small enough for the birds to carry in a backpack, New Scientist said.
The pigeons will take to the air at the inter-Society for Electronic Arts' annual symposium in San Jose on August 5.
The data they send back will be displayed on the blog in the form of an interactive map.
