• In this paper, we describe an automatic people-counting and environment monitoring system based on a wireless sensor network at a mountain area. Several people-counting systems and monitoring systems have been proposed separately. However, these systems are not suitable to a place such as the mountain area because of a few problems. In this paper, we develop a system which can count the number of visiting people and sense environment information to protect an ecosystem of the mountain area. For people-counting in the mountain area, our system uses two photo-beam sensors, a big rechargeable power and a solar power. Our people-counting method is automatically to count the number of incoming and outgoing people at a special point in real time. Moreover, the environment sensors measure environment information at the mountain area, and constitute the wireless sensor network with photo-beam sensors. To establish this system in Korea Mountains, we enforced tests on the wireless communications range and the reliability of people-counting. By the testing results, we found that the developed system is suitable within 200 meters for effective wireless communications in Korea Mountains. When the width of a path up a mountain is within 1.5 m, the reliability of people-counting in our system is over 90%.
