Abstract: A system for detecting an illuminance of the present invention includes a light source, a light sensor, and a signal output module. The light source includes a first A light-emitting diode, the first A light-emitting diode having a first color light; and the light source emits a first ray of light. The light sensor has a sensing face; the light sensor includes a first B light-emitting diode disposed on the sensing face, the first B light-emitting diode having the first color light; and the light sensor receives at least a portion of the first ray of light and generates a first sensing voltage. The signal output module is coupled to the light sensor to receive the first sensing voltage and output a sensing result signal according to the first sensing voltage.
