Industrial Remote Temperature Monitoring and Alarm System
Application Overview
Remote temperature monitoring for predictive maintenance can be used in almost any situation. Medical refrigerators, blood banks and food storage facilities are some example where remote wireless monitoring of temperature is essential.
The key requirements of avoiding wired or cellular connections, reliable operation in a multipath environment, ease of installation and the ability to analyze and resolve an analog signal (temperature) at high granularity and average it were met by DNT90 radio modules.
Temperature sensors were connected to multiple DNT90 radios across the facility and this information was sent wirelessly to another DNT90 radio module embedded in a master control circuit. The application then monitored the acceptable temperature ranges and raised the appropriate alarms as necessary.
Applicable Product Features
The DNT90’s ability to operate reliably in a multipath environment, multiple analog and digital inputs, intelligence to provide high granularity and averaging for analog input signals, ability to auto-report on analog values for alarms and a relatively high output power were some of the key factors in the choice of this radio module. The low cost allows systems to be economically priced.
