本文介紹一套光能驅動之無線感測器網路，用於建立便利商店內顧客舒適環境，並在舒適條件下進行有效的節能控制。在 M2M (men to machine, machine to men) 舒適度節能控制系統下，以光能驅動無線感測網路收集空間中所需物理量，並且利用 RFID 無線傳輸技術準確收集各節點之溫濕度及風速，以舒適度指標(PMV) 為控制回饋，找出空調最佳控制設定。控制前賣場內部舒適度分布在 0－0.5 之間，控制後賣場內部舒適度維持在 0.4 之間，而空調耗電量控制前耗電量每小時約為 1.8－2.0 kWh，控制後每小時約為 1.2－1.8kWh，節省 15% 以上之耗電量，創造便利商店實現智慧監控、節能管理等兩大功能。

The aims of this study are not only to provide customers a comfortable environment by controlling the temperature and lighting in a shopping area with a wireless sensor network but also to save power consumption. In a Men to Machine, Machine to Men (M2M) platform, a wireless sensor network powered with indoor-lighting is used to collect environmental data of temperature, humidity, and air velocity data. The collected data are transmitted to the platform by using a Radio Frequency Identifi cation (RFID) technique for determining the optimal settings of airconditioning.Before implementing the proposed M2M platform in a convenient store, the indoor Predicted Mean Vote (PMV) of the convenience store is 0－0.5 and the power consumption of air-conditioning is 1.8－2.0 kWh. After implementing the proposed M2M platform in a convenient store, the PMV is kept around 0.4 and the power consumption of air-conditioning system is reduced to a value of 1.2－1.8 kWh. The proposed platform can not
only save 15% of power consumption of air-conditioning of the convenient store but also to keep the same comfortable environment of shoppers in the convenient store.
