Abstract
A combination sensor may include a first infrared light sensor and a second infrared light sensor. The first infrared light sensor may be configured to sense light in a first wavelength within an infrared wavelength spectrum. The second infrared light sensor may be configured to sense light in a second wavelength that is different from the first wavelength within the infrared wavelength spectrum. The first infrared light sensor and the second infrared light sensor may be stacked in relation to each other.
