A refrigerator and freezer monitoring solution needs to perform 4 main tasks:
A monitoring solution will collect temperature data that is sensed using temperature sensors that are placed in a critical environment, in this case, refrigerators, freezers or cold rooms. The sensed data is transferred to the monitoring stations. The sensors are controlled through microcontrollers and data transmission process is wireless.
The performance of a sensor is characterized by:
- Transfer function,
- Sensitivity, Range,
- Resolution, and
Remote and Wireless Solutions
Remote monitoring systems are designed to control large or complex facilities such as manufacturing facilities, laboratories and other critical environments, with some degree of automation.
A remote or wireless monitoring solution will record data on a server and send alerts to those parties that need to be notified in case of an alarm, via text, email or phone.
A fully automated monitoring system helps restaurants, grocery stores, schools, professional kitchens and food manufacturing facilities maintain optimal quality of ingredients and prevent damage to valuable inventory and stock.
For medical refrigerators, according to FDA regulations, temperatures are required to be data logged. this process can and should be automated for reliability and prevention of human error.
Perishable foods are those likely to spoil, decay or become unsafe to consume if not kept refrigerated at 40 F° (4.4 °C) or below or frozen at 0 F° (-17.8 °C) or below. Examples of foods that must be kept refrigerated for safety include meat, poultry, fish, dairy products, and all cooked leftovers.
A temperature probe is a metal sensing probe that can be inserted into a refrigerator or freezer. Probe sensors for monitoring freezers and refrigerators can be used with hardwired or wireless applications to help you know if a temperature changes.
