Sensor Solutions for Cold Chain Logistics
Monitoring environmental conditions is crucial for many processes that impact our daily life. Fish that has been transported in an environment that is too warm might not only not taste bad but could also pose a danger to the consumer’s health. A drug that has been produced, transported, or stored under the wrong conditions will not have its intended effect. Plants that are grown in an unfavorable environment will most likely never reach their full potential or beauty. For all these and many more applications, data loggers are used to empower users to trace and manage environmental conditions accurately and comprehensively.
Sensirion develops and manufactures highly accurate and relieable sensors to be built into data loggers for further improvement of data quality. With its strong focus on innovation, Sensirion not only supports the needs of any monitoring application today but also shapes the future of what is possible in the future with groundbreaking new sensor technologies.
The Food and Agriculture Organization of the United Nations has found that one third of all food is wasted. For fruits and vegetables even up to 45% go to waste. All this totals in a yearly loss of $85 billion in the United States alone. Apart from the corresponding waste of land, water, and energy, the related greenhouse emissions would equal those of the world's 3rd largest emitter if it were its own country.
To reduce food waste, it is crucial to consider the entire supply chain from farm to fork. Many fruits and vegetables, such as bananas, are transported and stored in a controlled atmosphere (CA) to preserve freshness. Typically relevant CA parameters are carbon dioxide (CO2), humidity (RH), and temperature (T), even though strongly depending the exact commodity, often specified at a low temperature, high humidity and CO2 concentration somewhere between 1% and 20%. Proper monitoring and controlling of the transportation conditions allows to prevent losses by proactive action and thus improve the quality of the supply chain. Sensirion has just the right sensors for the job!
Sensirion offers new calibrated and certified humidity & temperature sensors for cost-efficent GDP-compliant drugs, vaccines, and perishable goods supply chain monitoring.
Temperature Defines Product Lifetime and Usability in Cold and Frozen Chain Logistics
Highly regulated products, such as pharmaceutical or perishable goods, typically require special handling along their distribution chain to comply with several directives such as the Prescription Drug Marketing Act of 1987, 21 CFR Part 203, Prescription Drug Marketing, and Part 205, or Guidelines for State Licensing of Wholesale Prescription Drug Distributors. Manufacturers are obligated to cover distribution in their overall quality system and must continuously adapt to adhere to current Good Distribution Practices for the pharmaceutical or perishable goods supply chain (also see PDA Technical Report #52). The most regulated parameter for drugs and perishable goods is temperature, which determines not only the lifetime, but the usability of a product. This often requires a product lifetime temperature profile within a narrow band.
Calibration for Reliable Temperature Monitoring over the Product Lifetime
Reliable temperature monitoring in the complexity of a modern logistics network requires trustworthy dataloggers, which are increasingly accepted only with certification from accredited laboratories (ISO17025). Today, loggers are typically equipped with several electronic components and often still with analogue temperature sensors, which makes accredited calibration of the complete device necessary, a time consuming and expensive step, which could be avoided using next-generation temperature sensing strategies.

ISO17025-Certified Humidity and Temperature Sensors
Sensirion, the first ISO17025-accredited semiconductor company in the world, has introduced a new series of ISO17025 calibrated digital sensors for a great variety of applications where precise and reliable measurements are required: Based on the versatile STS3x and SHT3x platforms, the STS32, STS33, and SHT33 are a digital, I2C-based temperature and humidity and temperature sensors, respectively. Metrological traceability of the calibration is conforming to ch.6.5 of ISO/IEC 17025:2017, commonly referred to NIST traceability or traceability to other national metrology institutes, according to the CIPM Mutual Recognition Arrangement (CIPM MRA). Have a look at Sensirion's achieved ISO17025 certification.

CO2 and Low-Cost Humidity and Temperature Sensors
The STC31 is a chip-sized gas concentration sensor for high range, accurate CO2 measurements designed for high-volume production. The sensor is based on a revolutionized thermal conductivity measurement principle, which results in superior repeatability and long-term stability. This makes the STC31 the perfect choice for applications where reliability is key. Thermal conductivity technology has an ultra-low power consumption, even compared to low-power optical sensor. This makes it the ideal choice for battery operated applications, delivering top-performance at an absolute minimal power budget.
In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT40 offers the best price-performance ratio on the market. Tape and reel packaging combined with its suitability for standard SMD assembly processes make the SHT4x ideal for high-volume applications. The SHT40 builds on a completely new and optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications. With the extended supply voltage range from 1.08 V to 3.6 V, it’s the perfect fit for mobile and battery-driven applications.

ELPRO Datalogging Solutions
Reliable temperature monitoring in the complexity of a modern logistics network therefore requires trustworthy data loggers, which are increasingly (pushed by regulations such as EN 12830) accepted only with certification from accredited laboratories (ISO 17025). ELPRO offers a wide range of data logger solutions for every customer need. The LIBERO Cx multi-use series with Bluetooth provides the foundation for next-generation independent monitoring solutions for products with known stability data. Going a step further, the LIBERO Gx series enables real-time data logging, providing 24/7 access to shipment, location and condition data, including temperature, humidity, light, tilt and shock. The 1-year battery life protects shipments further and longer around the globe.
At ELPRO, we live and breathe quality and compliance – they are the foundation of our customer relationship and the trust in our products and services. For this purpose, we have to ensure that the chips for our temperature data loggers correspond exactly to the specifications that were defined during development. The nature and scope of routine checks and controls is heavily dependent on Sensirion, who has been the perfect partner in the development of these chips and has incorporated the needs of ELPRO and our customers into production.

Tive's Real-Time Tracking Solutions
Supply chain management in a large variety of sectors relies on on-time and uncompromised delivery of goods. Increasingly, efficient supply chains require tracking of shipment conditions in real time. Next to handling of perishable goods, high-tech electronics and specialty foods, the distribution of pharmaceutical products, such as vaccines, is particularly highly regulated. Therefore, manufacturers are obligated to cover distribution in their overall quality system and must often adapt to adhere to current Good Distribution Practices as in the pharmaceutical or perishable goods supply chain (also see PDA Technical Report #52). Tive’s in-transit visibility solution replaces passive data loggers with real-time visibility into the location and condition (temperature, humidity, shock and light) of sensitive cold chain goods such as pharmaceuticals. And with Sensirion’s cutting-edge 3-point calibrated sensors, Tive continues to expedite the delivery of ISO-certified industry-compliant solutions that fit the demanding requirements of shippers and logistics service providers (LSPs) focused on moving life-saving vaccines and their ingredients.
