LoRaWAN water quality chlorophyll sensor is a device for measuring chlorophyll concentration in water bodies; The design method of using fluorescence principle and optical fiber to conduct the optical path; Internally added filtering algorithm, with strong resistance to external light interference. Built in temperature transmitter, capable of automatic temperature compensation. The device outputs relative fluorescence units, which facilitates the analysis of the relationship between fluorescence intensity and chlorophyll concentration based on actual conditions.Supports LoRa TDMA networking and standard LoRaWAN protocol.

Many organic compounds in water absorb ultraviolet light. The concentration of dissolved organic pollutants can be accurately measured by detecting their absorbance at 254 nm. The ZW‑COD‑PR online COD sensor uses dual light sources: one UV light for COD measurement and one reference light for turbidity compensation. With optical path attenuation correction and algorithm optimization, it effectively reduces interference from suspended particles and provides stable and reliable measurement.
