The invention discloses an Internet of things air switch based on demand side power utilization management. The switch comprises a control module, a power supply module, an action module and an electric energy metering module. Power utilization parameter information such as a current, a voltage, active and reactive power and the like of power utilization equipment can be acquired through the electric energy metering module, and power monitoring of power utilization equipment is realized. Moreover, the Internet of things air switch also comprises a communication module and a data cloud end so as to realize communication connection with the data cloud end through the communication module. In addition, the communication module comprises an NB-Iot unit and a Wifi unit so that a user can monitor a power utilization condition of the power utilization equipment under the conditions that there is a network and there is no network.
