Car crashes are expensive. At best, they are a time-consuming nuisance. At worst, they are deadly. According to the Insurance Institute for Highway Safety, 1 in 5 car crashes occurs in parking lots. That’s why we started Carduino Sensors. We make low-cost Arduino-powered distance sensors that attach to the corners of cars to assist in parking situations, thereby significantly reducing the number of car accidents. This is an inexpensive solution to a costly problem. By making parking safer and more efficient, Carduino Sensors helps traffic roll along more smoothly, thus reducing emissions and congestion as well.
