Product information "DRAGINO · Sensor · LoRa · Water Quality Sensor · WQS-LB-EU868"
The Dragino LoRaWAN water quality sensor series products are designed to measure water quality and provide information on water quality conditions. They consist of a main process unit (WQS-LB) and various sensors.
The sensors include various types such as: pH sensor, ORP sensor, EC sensor, dissolved oxygen sensor and turbidity sensor.
The main process device WQS-LB is a LoRaWAN RS485 end node for outdoor use, which is powered by a built-in lithium-ion battery. WQS-LB reads values from various sensors and uploads this sensor data to the IoT server via the LoRaWAN radio protocol.
WQS-LB is fully compatible with the LoRaWAN Class C protocol and can work with standard LoRaWAN gateways.
