Water Quality Sensor based on LoRaWAN®
Water Float Station:
A large floating station is an intelligent monitoring device that can adapt to offshore monitoring operations, which can float on the lake, reservoir or dam for a long time to monitor the real-time environment. This system mainly applies to monitor pure water quality for a long time. The product is equipped with a dual solar panel power supply & 12Ah Rechargeable Li-Ion battery so that it won't be affected by the direction of the sun, greatly extending the working hours, energy saving, and environmental protection.
WSC1-L -- Main Process Unit:
WSC1-L is the main process unit in Dragino Weather Station solution. WSCL-1 is an outdoor LoRaWAN RS485 end node. It is powered by external 12v solar power and has a built-in li-on backup battery. WSC1-L reads values from various sensors and upload these sensor data to IoT server via LoRaWAN wireless protocol. WSC1-L is full compatible with LoRaWAN Class C protocol, it can work with standard LoRaWAN gateway. Each WSC1-L is pre-load with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto-connect after power on.
