Application
Tips: How does the sensor measure oil in water?
The water quality sensor measures oil in water using the fluorescence method, which detects the light emitted by oil particles when exposed to specific ultraviolet (UV) wavelengths. This method is highly sensitive and effective for detecting low concentrations of oil. When UV light hits the oil particles in the water, they emit fluorescence, which the sensor captures and converts into a measurable signal. The fluorescence intensity is directly proportional to the oil concentration, allowing for precise and reliable measurements. Additionally, the sensor's advanced filtering system minimizes interference from ambient light or other environmental factors, ensuring accurate results even in challenging conditions.
