WQS-LS - Solar Powered LoRaWAN Water Quality Sensor Transmitter

The Dragino WQS-LS is a main unit which allows connecting 1 to 3 water quality probes, including EC, pH, DO, ORP and TS probes. It detects water quality parameters and uploads the value via wireless to a IoT Server via LoRaWAN network.

This device supports BLE and LoRaWAN remote configure which makes it very easy to adapt the device. It also supports wireless OTA to update the firmware.

WQS-LS is powered by a rechargeable battery with solar cell and allows continuous use.

Each WQS-LS is pre-loaded with a set of unique keys for LoRaWAN registrations. If you register these OTAA keys to the local LoRaWAN server (e.g. TTN), then it will auto connect after power on.

More information is available in the datasheet and on the website of Dragino.
