An ultra violet light sterilizing apparatus (10) includes in one embodiment a fluid chamber (18), at least one ultraviolet light source (16) configured to emit ultraviolet light into the fluid chamber (18), and at least one ultraviolet light sensor (12) that includes a photodiode (36). The photodiode (36) is a silicon carbide photodiode, a gallium nitride photodiode, or an aluminum gallium nitride photodiode. Each UV light sensor (12) includes a sealed outer housing (32) having an optically transparent window (34). The photodiode (36) is located inside the housing (32) adjacent the transparent window (34). Each UV light sensor (12) also includes a signal amplification unit (40) that includes an amplifier (44) mounted on a printed circuit board (46) located inside the housing (32). The UV sterilization apparatus (10) also includes a controller (14) configured to receive, as input, a signal from each ultraviolet light sensor (12). The controller (l4) compares the input signal to a desired UV light intensity and outputs a control signal to each ultraviolet light source (16) to adjust the intensity of the ultraviolet light emitted from each ultraviolet light source (16).
