Abstract: A method for command transmission and configuration to sensor implemented by ambient light source is disclosed and adopted by a sensor having a light-sensing unit. The sensor collects ambient light time series data through the light-sensing unit, and extracts valid brightness toggle data therefrom.

When receiving the confirmed brightness toggle data within a waiting period after outputting the flashing signal, the sensor automatically performs the pre-stored command corresponding to the matched triggering condition.
