COLD CHAIN AND RETAIL REVOLUTIONIZED BY IOT DIGITAL TEMPERATURE SENSOR

COLD CHAIN AND RETAIL REVOLUTIONIZED BY IOT DIGITAL TEMPERATURE SENSOR

Traditionally, the cold chain has relied on manual temperature monitoring and control, which can be time-consuming and prone to error. However, the increasing adoption of IoT digital temperature sensor is revolutionizing the cold chain and retail industries.

The cold chain refers to the network of temperature-controlled logistics and supply chain management systems that are used to transport and store perishable goods, such as food, pharmaceuticals, and chemicals. Ensuring that these goods are kept at the proper temperature throughout the supply chain is critical to maintaining their quality and safety.

IoT temperature sensors are small, connected devices that can be placed on or inside packages, pallets, or storage units to continuously monitor and transmit temperature data. This real-time data can be accessed and analyzed by logistics and supply chain managers, allowing them to quickly identify and address any deviations from the desired temperature range.

Benefits of IoT Digital Temperature Sensor

  • IoT temperature sensors can provide early warning of potential temperature excursions. 

For example, if a package of perishable goods is being shipped by truck and the ambient temperature outside the trailer rises unexpectedly, the sensors will detect this and alert the relevant parties. This allows for proactive corrective action to be taken, such as rerouting the shipment to a cooler location or adjusting the temperature inside the trailer.

  • IoT temperature sensors also improve efficiency and reduce waste by enabling more precise temperature control. 

For example, in a retail setting, sensors can be used to monitor the temperature of refrigerated cases and adjust the cooling system, accordingly, ensuring that the products are kept at the optimal temperature while minimizing energy consumption.

  • IoT temperature sensors provide a wealth of data that can be used for continuous improvement and optimization of the cold chain. 

For example, data on temperature patterns and trends can be used to optimize routing and storage, while data on individual shipments can be used to identify and address bottlenecks or inefficiencies in the supply chain.

Sensing high temperatures with heat sensors

For industrial applications, particularly for sensing high temperatures, heat sensors are essentially an improved form of temperature sensors. The term “heat” normally refers to temperatures over 50 degrees centigrade (122 degrees Fahrenheit) and up to a high of about 2400 degrees centigrade (4352 degrees Fahrenheit). 

Since the sensor itself shouldn’t be harmed at greater temperatures, the heat sensor gets more sophisticated as the temperature rises. Thermocouples and unique pt100 sensors are utilized to monitor temperature at greater temperatures. A Tungsten Rhenium thermocouple is used to calibrate a heat sensor to monitor temperatures up to 2400 degrees Celsius.

Pt100 sensor for measuring temperature

The most used kind of temperature sensor is Pt100. As previously stated, these sensors likewise operate on the tenet that a conductor’s resistance changes with temperature. Platinum, the material used to make the PT 100 sensor, has a resistance of 100 Ohms at 0 °C and 138.4 Ohms at 100 °C.

Pt100 sensors are employed in a rough temperature range of 250 to +900 °C. The linear character of the resistance fluctuation over the full temperature range is determined from the corresponding resistance and temperature graphs. Platinum is a useful material for measuring very high temperatures because of its strong temperature tolerance capabilities.

A Final Note

Overall, the use of IoT temperature sensors is transforming the cold chain and retail industries by enabling more accurate and efficient temperature monitoring and control. This, in turn, helps to improve the quality and safety of perishable goods and reduce waste and energy consumption. 

As technology continues to evolve and become more widely adopted, we can expect to see even greater benefits and efficiencies in the cold chain. For more details, Contact us at sensors.en@vackerglobal.com
