The estimation of the number of people is useful for various situations. In this paper, hybrid estimation method of the number of people in a room is proposed. This estimation method is achieved by using CO2 sensor and motion sensor. Adaptive adjusting method of hold time for motion sensor is also proposed for its self-calibration. Proposed method was implemented on an energy management system and evaluated in a classroom environment. This evaluation proves that proposed method can improve the precision from 0.9 in the previous method to 0.4 in the proposed method at the number of people.
