Abstract
A system for detecting leaks of petroleum and other non-petroleum based products in an environment includes a sensor package comprising at least one 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 a fluorescing mixture, such as a petroleum based product, 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.
