We propose the presence detection method using the Bluetooth, and evaluate it. The existing products and technologies to detect a presence have some problems. For example, these are security threat caused by human error, expensive introduction cost, and detection accuracy. Firstly, we analyzed a characteristic of Bluetooth's RSSI (Received Signal Strength Indication) from preliminary experimental results to solve these problems. As a result, we proposed the method that combines processing using RSSI's threshold and exception handling for instantaneous variation of RSSI. Then we decided optimum value of parameters for the method by various performance evaluation tests, and finally, we verified usability of the proposed method.
