temperature logger part 6 schematics pcb and source code
The described system integrates a FAT12 filesystem to facilitate the management of data storage on custom flash drives, specifically tailored for projects requiring data logging capabilities. The use of Microchip Applications libraries allows for compatibility with the Device Mass Storage SD Card data logger, enhancing the versatility of the solution.
The USB temperature logger functionality is central to the design, enabling real-time temperature monitoring and data logging. The source code serves as a foundation that can be expanded upon, allowing developers to introduce additional features or optimize existing functionalities.
One critical aspect that requires attention is the robustness of the logger, particularly regarding power management. Implementing a power failure detection mechanism would significantly enhance the reliability of the logger, ensuring that data integrity is maintained even in the event of unexpected battery depletion. This could involve the use of capacitors to provide a buffer during power loss or implementing a software routine that safely shuts down the logger upon detecting low battery conditions.
Furthermore, the PCB design includes provisions for monitoring battery voltage, which is a vital feature for maintaining operational reliability. The firmware must be updated to utilize this capability, allowing for real-time voltage readings that can trigger alerts or safe shutdown procedures when voltage drops below a critical threshold.
In summary, the integration of a FAT12 filesystem, USB temperature logging capabilities, and robust power management features positions this project as a comprehensive solution for data logging applications. Future enhancements to the source code and firmware will further solidify its reliability and functionality in various operational environments.The source code contains a FAT12 filesystem that can be reused to make custom flash drives for other projects. The source code (based on Microchip Applications libraries -Device Mass Storage SD Card data logger- MPLABX): Simple USB temperature logger source code The source code could be improved to increase the robustness of the logger (especially in the case of battery power failure
while on logging mode). The PCB allows the monitoring of the battery voltage, it just needs to be implemented in the firmware. 🔗 External reference
