LoRaWAN Water Quality Sensor Converter

The Dragino WQS-LB/LS is an advanced LoRaWAN end device designed for comprehensive water quality monitoring across various applications. It is ideal for ensuring water quality in tap water, industrial water, environmental water, and wastewater, offering precise and reliable measurements to meet water quality standards. Communication between all water quality sensors and nodes is implemented through the RS485 bus and the Modbus protocol is used as the communication standard. This design has high reliability and strong anti-interference ability, and is especially suitable for data acquisition and transmission in industrial environments or complex scenarios. The RS485 bus supports multi-point communication and can connect multiple sensors and node devices to form a stable data communication network. The system's modular design allows each water quality sensor to be disassembled and installed independently. When a sensor needs to be replaced or maintained, simply remove the target sensor from the current RS485 bus network. These sensors also allow easy access to other reading devices that support the RS485 interface. For example, you can install sensors into different data acquisition terminals, controllers, or monitoring systems without additional hardware modifications or complex configuration tweaks. Note1: The method of use is that the probe is in direct contact with the water quality. Before using the sensor probe, its protective cover and blue foam cushioning pad must be completely removed. These protective components are designed for transportation and storage, and can effectively resist factors such as physical collision that damage the probe.
