This trackable device utilizes Hazard Analysis Critical Control Points (HACCP), an international management system, to control temperature during food transportation. It employs cellular communications to send temperature information to the server at regular intervals across a wide area. This trackable and low-power device, with an MQTT communication function via the cellular LTE module and a microcontroller as the host, ensures maximum battery life.

System Benefits:

  • Wide area transmission using cellular communication
  • MQTT communication with simple packets and a low-power MCU to maximize battery life
  • Comprehensive support to shorten design time
  • LTE Cat-M1 cellular IoT module that can be easily connected to a microcontroller evaluation board
  • Sample program for controlling the LTE module
  • Temperature sensor control software




  • Cold chain management
  • Trackable devices
  • Distribution tag
