Remote Temperature Monitoring for Refrigerators, Freezers and Cold Storage

Remote Temperature Monitoring for Refrigerators, Freezers and Cold Storage

MEI 20/10/2026 0
Refrigerators, freezers, cold rooms, and other temperature-controlled storage areas often require continuous temperature monitoring rather than occasional manual checks.By connecting temperature sensors to a Microedge data logger, temperatures can be recorded automatically, viewed in real time, and monitored remotely through a PC or web browser. Alarm thresholds can also be configured to help identify temperatures that move outside the desired range.This Application Note shows several practical ways to build a remote temperature monitoring system using Microedge data loggers and software.  1. Application Typical applications include:RefrigeratorsFreezersWalk-in coolersCold roomsFood storage areasLaboratory refrigeratorsPharmaceutical storageEnvironmental chambersTemperature-controlled warehousesA typical monitoring system consists of:Temperature Sensor → Data Logger → Network → Monitoring Software → Browser / PCThe data logger records temperature continuously while the monitoring software provides access to current and historical data.  2. Choosing the Temperature Sensor The most appropriate sensor depends on the temperature range and installation.ThermocouplesThermocouples are use...

Thermistor and Water

MEI 20/05/2018 0
An NTC thermistor is designed to measure temperature changes in different applications, but it is truly ideal for working in liquids (such as water). This is a result of long-term reliability and stability. They are the most accurate temperature gauges (when compared to a thermocouple), which allows for extremely close readings.A thermistor placed in water will most likely stay in one place for extended periods of time. A thermistor offers long-term durability for thermistor in water-based applications. A thermocouple will begin to weaken, which degrades its ability to read temperature accurately. Having to consistently replace thermocouples will intermittently stop production.A study about water temperature changes in Lake Tahoe has just recently ended. It was a 40-year study that suggests global warming is responsible for an increase in temperature in the lake (there has been a consistent rise over the last four decades). This is a big problem for the current habitat of the lake, and the warmer water threatens to destroy the whole eco-system.NTC thermistors were extensively used for this study because of their high accuracy rates. The thermistors helped to prove that the temperat...
