    Abstract: A system for detecting leaks of petroleum based products in containers includes a sensor package comprising an LED and an optical photo-detector. The emitter transmits an excitation signal with an excitation wavelength, and the detector is tuned to the emission wavelengths of the petroleum based liquid in a space where detection is sought. An alarm system coupled to the detector may be used for notifying users in case of a leak.
