Vehicle Safety Sensor Dr. Rich Fletcher, Cheng-Wei Pei, and Professor Hiroshi Ishii / 2003
We have built a low-cost ($10) 2.4 GHz Wireless safety sensor for vehicles. This
transceiver and antenna mounted to the driver-side car door could prevent dangerous
and costly traffic accidents or personal injury to bicyclists and other motor
vehicles. We are currently building a longer-range version of this sensor for
US Postal vehicles.
