LoRaWAN water quality DO sensor - copy

The LoRa water quality DO sensor is a device that uses fluorescence measurement principles to measure the concentration of dissolved oxygen in a solution. It does not consume oxygen and does not require electrolytes. Built in temperature transmitter with automatic temperature compensation function. The calibration function provides a simpler and more convenient calibration method. The use of imported high-quality fluorescent films can be widely applied in industries such as water treatment, aquaculture, and environmental monitoring. Supports LoRa TDMA networking and standard LoRaWAN protocol.
