Silanna UV’s SF1 series UV LEDs, leveraging the company’s short period superlattice technology, are ideal for nitrate detection, sterilization, and water/gas sensing. SF1 series UV-C emitters operate with a peak wavelength under 235nm and a full-width-half-max (FWHM) of 10nm. To help users evaluate this new technology and develop products based on it, the company also created a nitrate sensing reference design featuring the company’s SF1 series LEDs. The module rapidly and accurately measures the nitrate content of a liquid sample. The microcontroller-based reference design features a capacitive touch display, safety interlock, and compensates for thermal effects to maintain accuracy and avoid warm-up delay. The UV-C LEDs package’s built-in 30-degree parabolic lens eliminates the need of secondary optics, making the system even more compact and cost effective.
