Key takeaways

  • M4 Pro and S05T sensors provide real-time temperature tracking, accurate to ±0.5 degrees C (33 degrees Fahrenheit), for perishable goods transport.
  • BLE connectivity and cloud access allow fleets to monitor temperature deviations promptly, reducing product loss.
  • Ultra-low power and rugged design enable long battery life and reliable operation in refrigerated trucks and extreme conditions.

Mokosmart and Silicon Labs recently launched the M4 Pro and S05T temperature sensors aimed at improving cold chain transportation. Mokosmart brings rugged and scalable devices to industrial applications to the partnership, and Silicon Labs provides BG22 SoCs that enable ultra-low power consumption and high-performance connectivity.

The sensors are designed for cold chain transportation, helping businesses track temperature-sensitive goods from food to pharmaceuticals. By providing reliable data and timely alerts, the devices help prevent asset losses and maintain product integrity throughout the supply chain.

Key features of M4 Pro and S05T temperature sensors:

  • Low power consumption: BG22 SoC enables exceptional energy efficiency and extends battery life up to two years.
  • Compact and rugged design: Small form factor with IP67-rated enclosures allow for easy installation and protection in extreme environments.
  • Real-time temperature and location tracking: Bluetooth Low Energy (BLE) connectivity allows cloud access to precise temperature data for proactive monitoring.

“From our aspects, cold chain operators need solutions that are not only reliable but also sustainable,” Jerry Li, cofounder of Mokosmart, said. “Our collaboration with Silicon Labs combines their world-class wireless expertise with our deep understanding of industrial IoT applications. The cooperative temperature sensors can deliver unmatched accuracy, longevity, and ease of deployment, empowering businesses to be aware of any temperature fluctuations and safeguard their assets better.”
