RS-485 to MQTT Converter

RS-485 to MQTT Converter
Product Description


RS-485 to MQTT Converter or SIM IoT Gateways are those type of Data Converters which stream the sensor data to cloud-hosted software platform of Ambetronics. They are highly scalable and offers unlimited sensor data storage, powerful analytics and search, real-time visibility and alerts, and intuitive dashboards.

Remotely monitor industrial sensors, from pressure to temperature, tank levels, flow, and gas levels.
SIM operates effectively as a stand-alone industrial monitoring solution.
