With the intensification of industrialization and seawater intrusion, the concentration of chloride ions in water has become a key indicator for evaluating water quality safety. However, traditional monitoring devices rely on power supplies and wired connections, making them difficult to deploy in remote or outdoor off-grid scenarios, which poses major challenges for environmental protection autho...
Online monitoring of water quality nitrite has long faced a dilemma where accuracy and transmission distance cannot be optimized simultaneously. Electrochemical sensors deliver accurate data but suffer from complicated wiring; wireless transmission offers great convenience yet often fails to operate long-term in field environments due to high power consumption. The LW116D LoRaWAN Integrated Nitrit...
