1. A projection apparatus, comprising:
a processor, a sensor, and a projection module, wherein
the processor is respectively coupled to the sensor and the projection module,
the processor is configured to:
set the projection apparatus to a first sub-standby mode when receiving a command corresponding to a standby mode;
enable the sensor to sense whether there is a living object located in a sensing area outside the projection apparatus;
maintain the standby mode as the first sub-standby mode in response to sensing that the living object is not in the sensing area; and
set the standby mode to switch from the first sub-standby mode to a second sub-standby mode in response to sensing that there is the living object in the sensing area, wherein
a maximum power consumption of the projection apparatus in the first sub-standby mode is less than a maximum power consumption of the projection apparatus in the second sub-standby mode, and in the first sub-standby mode and the second sub-standby mode, the projection module is not enabled.
