Applications

The compact and low-power architecture can be adapted for various standalone data acquisition and field monitoring applications.

  • Environmental sensor data logging
  • Temperature and humidity monitoring
  • Agricultural and greenhouse monitoring
  • Remote equipment monitoring
  • Industrial condition monitoring
  • Battery-powered field data acquisition

Hardware Design

The PCB was designed as a compact 4-layer board using KiCad. Particular attention was given to component placement, power distribution, signal routing, and the I²C connections between the microcontroller, EEPROMs, and RTC.
