Sentinel Monitoring System Keeps Foods Safer: Alerts Personnel to Temperature Changes Inside Food Storage Freezers and Coolers

ASTON, Pa., May 15, 2023 – Ensuring food safety and complying with regulations requires constant monitoring and maintenance of cold storage units. Sensaphone has developed the Sentinel™ monitoring system to help industry professionals responsible for food product storage. This cloud-based system offers remote supervision of temperatures inside industrial refrigerators and freezers, and other conditions that may affect cold storage units.

With the Sentinel system, operators can monitor refrigerator and freezer temperature, as well as ambient room temperature, humidity, vibration, carbon monoxide, carbon dioxide, water leaks, power failure and unauthorized access. If a sensor reading moves outside the preset range, the system sends a notification via phone call, text or email to designated personnel for fast corrective action.

The Sentinel system is perfect for food manufacturing, processing and storage facilities, research and testing laboratories, food service establishments and retail locations. Operators can access real-time data around the clock from anywhere using a mobile device or computer. They can also check status information, change settings, disable alarms and readjust temperature limits from the Sensaphone app.  

The system provides unlimited data logging of critical environmental conditions over time, helping operators to identify potential equipment issues before they become major problems.

Sensaphone offers both cellular and Ethernet versions of the Sentinel system, housed in a NEMA 4X enclosure for protection from dust, dirt and moisture.

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 there is a cellular communications problem. Users are notified through phone, text or email about the disruption.
