Sensaphone® will introduce its Sentinel™ PRO remote monitoring system, an enhanced version of the Sentinel cloud-based system that provides 24/7 remote monitoring of unattended HVAC units, freezers, refrigerators, boilers, and chillers. The Sentinel PRO system supports the Modbus communications protocol and includes a second relay output — capabilities required to monitor and control complex networks.

The Sentinel PRO system interacts with all existing sensors within a facility and introduces operators to the Internet of Things for on-demand, real-time status and data acquisition from any internet connected device. It can collect data and push it to the cloud for alarming, reporting, and real-time status.

The system monitors, delivers alarms, and datalogs input/output points from third-party Modbus sensors, transducers, and programmable logic controllers (PLCs). These sensors can monitor virtually any critical condition including temperature, humidity, pressure, pH, conductivity, and water leakage. The system supports Modbus RTU/485 and Modbus TCP.
