Sensaphone Sentinel PRO Version Coming May – 2016

Building on the success of the Sensaphone Sentinel and Sentinel Cellular cloud based devices the Sentinel Pro has now been developed. There has long been a need for a wireless (3G etc.) modbus gateway. The system monitors, delivers alarms, and datalogs input/output points from third-party Modbus sensors, transducers and programmable logic controllers. The system supports Modbus RTU/485 and Modbus TCP.

Key differences between the Sentinel and Sentinel PRO models:

I have been in the alarm and control industry for the past 8 years. I am especially interested in the utilization of existing WiFi networks for alarm notification and control applications.

    • I have been in the alarm and automation industry since 2006. I am particularly interested in seeing how the industry adapts as the number of home owners with traditional land line phone lines dwindles raising a need for WiFi and Cellular devices.
