Tips: How does the fluorescence detection method work in the RS485 Chlorophyll Sensor?

The RS485 Chlorophyll Sensor utilizes fluorescence detection, a method that measures chlorophyll by detecting the light emitted by chlorophyll molecules when excited by a specific wavelength. Chlorophyll fluoresces under blue or UV light, and this emitted light is captured and quantified by the sensor. This non-invasive method provides high sensitivity, allowing the sensor to detect even low concentrations of chlorophyll in water. The fluorescence method is preferred for chlorophyll measurements as it avoids chemical reagents, minimizes environmental impact, and maintains accuracy over a range of conditions.
