Protect Refrigerated and Frozen Food Inventories with Sentinel Monitoring System

ASTON, Pa., May 13, 2019 – The Sentinel™ system from Sensaphone® uses cloud technology to provide supervised 24/7 remote monitoring of temperatures inside industrial food refrigerators and freezers and other environmental conditions that can affect the operation of cold storage units. The system is ideal for food manufacturing, processing and storage facilities, research and testing laboratories, food service establishments and retail locations.

Each unit monitors up to 12 different environmental and equipment status conditions including temperature from -109 °F to 168 °F (-85 °C to 76 °C), humidity, water detection, power failure and more. When the system detects that a sensor reading has moved out of the preset range, it sends notification via phone call, text or email to designated personnel for fast corrective action. 

Operators can access real-time data from anywhere using any mobile device. Its user-friendly cloud functionality lets users check status information, change settings, disable alarms and readjust temperature limits right from the Sensaphone app.  

The Sentinel system also has enhanced data logging functionality that allows users to print, graph or export accurate historical records. This advanced data logging capability saves personnel time and effort when reporting on operating conditions or demonstrating regulatory compliance, because the system makes it easy to maintain records and generate time- and sensor-specific reports.

The Sentinel system constantly communicates a signal to the Sensaphone cloud to validate its online status. If the communication link is interrupted—for example by a power outage or someone accidentally switching off the unit—the system generates an alert indicating that internet connection is lost or that there is a cellular communications problem. Users are notified about the disruption through phone, text or email.
