LoRa water quality COD sensor

The LoRa water quality COD sensor is a device for measuring the chemical oxygen demand (COD) of a solution, using ultraviolet absorption method without the need for chemical reagents; Internally integrated self-cleaning system, effectively preventing biological attachment; Built in temperature transmitter with automatic temperature compensation function; Using modulated optical signals to reduce visible light interference; Equipped with a turbidity measurement system to effectively compensate for the impact of turbidity on COD measurement. Supports LoRa TDMA ad hoc networks and standard LoRaWAN protocols.
