Water Quality Sensor Converter with GNSS – NB-IoT / LTE-M

A cellular converter that connects one to three water quality probes — EC, pH, dissolved oxygen (DO), ORP, suspended solids (TSS), chlorine or COD — and reports their readings over NB-IoT or LTE-M (CAT-M1), with no gateway to install. Built-in GNSS adds the unit's location to each report, which helps when monitoring points are spread across rivers, reservoirs, canals or mobile installations. Data is sent via MQTT, MQTTS, TCP, UDP or CoAP to NARA, where treatment plants, fish farms and utilities can track water conditions and set alarms. An 8,500 mAh battery supports long unattended deployments, and settings and firmware are updated over Bluetooth 5.1.
