LoRaWAN water quality sodium ion sensor is a wireless sensor used to measure the concentration of sodium ions in water. The sodium ion sensor adopts a sodium ion selective electrode based on polyvinyl chloride membrane and has temperature compensation function, ensuring fast, simple, accurate and economical detection. Connect to the LoRaWAN collector through an aviation connector to achieve wireless communication. Widely used for online automatic continuous analysis and detection of ions in industrial wastewater, surface water, drinking water, and agricultural production process control.
