The invention is related to a self-powered sensing device, which comprises an optical wave guide element, a self-powered battery which comprises at least one photovoltaic, a sensor, an adjusting circuit which is electronically connected in between the self-powered battery and the sensor for providing electricity generated from the self-powered battery to the sensor, and a signal transmission element, which is electronically connected to the sensor; wherein the photovoltaic comprises a light receiving surface and the optical wave guide element guides the light incident on the self-powered sensing device to the light receiving surface of the photovoltaic. The photovoltaic equipped with the optical wave guide element captures indoor weak light nearby the self-powered sensing device and steadily provides the sensor with the required electricity such that the sensor can continuously sense environment while the maintenance fee required for replacing batteries thereof can be reduced.
