In today’s global economy, efficiently managing temperature-sensitive products throughout the supply chain is more than just important, it’s essential. With globalization expanding the reach of goods, products now travel across vast distances and diverse climates, introducing complexities in distribution. This makes it increasingly challenging to preserve the integrity of perishable goods, pharmaceuticals, and other sensitive items. The process of managing these temperature-controlled shipments is known as cold chain logistics. For instance, the onset of COVID-19, significantly increased the demand for temperature-sensitive medications and vaccines, making reliable cold-chain management critical. Over $260 billion in annual biopharma sales rely on maintaining strict temperature controls to ensure product efficacy. As the demand for these essential goods continues to rise, so does the need for advanced solutions that can safeguard the integrity of cold chain logistics.
Cold chain logistics faces a range of challenges that must be overcome, including precise temperature control, ensuring real-time product tracking, guaranteeing equipment reliability, managing data effectively, optimizing energy efficiency, and adhering to regulatory standards. Addressing these issues is essential to preventing product spoilage, financial losses, and potential health risks. As a result, robust and reliable solutions are therefore essential to safeguarding product quality and safety throughout the supply chain.
Renesas’ Trackable Cold Chain Management winning combination offers several benefits that directly address the challenges faced in cold chain logistics.
- Temperature Control and Regulatory Compliance: The system complies with Hazard Analysis Critical Control Points (HACCP) principles, an international preventive food safety approach that addresses biological, chemical, and physical hazards via analysis and control, from production to final consumption. For instance, the HS3001 humidity and temperature sensor, with proprietary sensor level protection, ensures high reliability and stability, and can quickly detect any deviations from critical limits for timely corrective actions. By incorporating this protocol, Renesas ensures the solution meets stringent international food safety standards.
- Real-Time Product Tracking: Temperature is continuously monitored and transmitted using cellular communication over a wide area and sent to a server at regular intervals. For instance, in supply chain products such as high-end wines, real-time tracking provides visibility into the location and condition of the goods. If the temperature or handling conditions fall outside acceptable ranges, alerts can be sent to the relevant parties for corrective action, preserving product quality and authenticity.
- Efficient and Reliable Data Transmission: This system uses Message Queuing Telemetry Transport (MQTT) communication, a lightweight messaging protocol that uses simple packets, making it ideal for low-bandwidth, high-latency, or unreliable networks, enabling efficient, reliable data transmission while conserving power. For example, a distribution tag on a frozen goods shipment can send periodic temperature and location updates via MQTT, ensuring consistent monitoring throughout long-distance shipments, including across continents, without quickly draining the battery.
- Low-Power Design: The RL78/G23 general-purpose MCU, expands the RL78 family, offering the industry’s lowest power consumption with 41μA/MHz operation and just 210nA in stop mode with 4KB of SRAM retention, and expanded peripheral functions. Its intelligent snooze mode further reduces power consumption during intermittent operation, ensuring prolonged battery life and reliable monitoring of temperature-sensitive products, which is essential for maintaining product integrity throughout the entire supply chain.
- Comprehensive support for faster design: The system comes with:
- An LTE Cat-M1 cellular IoT module that can be easily connected to a microcontroller evaluation board.
- Sample program for controlling the LTE module.
- The sensor control module for Renesas’ HS3001 humidity and temperature sensor uses a Software Integration System (SIS). These control modules acquire the sensor data using the IIC Communication (Master mode) component and calculate relative humidity and temperature values.
This Trackable Cold Chain Management winning combination effectively addresses the multifaceted challenges of cold chain logistics, ensuring product safety, quality, and compliance throughout the supply chain. By integrating advanced features such as precise temperature control, real-time tracking, efficient data transmission, low-power design, and comprehensive support, this solution paves the way for enhanced efficiency and dependability in managing temperature-sensitive products.
