Self made data-logger V2.5

The new data-logger software is not yet completely finished. But the hardware design is frozen and will probably not be changed anymore. The printed circuit board is a bit smaller than the old one (36x22mm). But unfortunately the new one can measure analog input signals only with 10 bit resolution. More: The sensor for barometric altitude and its amplifier are contained on the printed circuit board now. Since the dissolution of altitude (10 bit) is too rough for the climb rate, an additional circuit is on the board. An amplifier for current measurements.

The data-logger hardware design features a compact printed circuit board (PCB) measuring 36mm by 22mm. This size reduction from the previous design allows for a more efficient use of space, potentially enabling integration into smaller enclosures or devices. The PCB incorporates a sensor for measuring barometric altitude, which is essential for applications that require altitude data, such as in aviation or environmental monitoring. This sensor is accompanied by an amplifier to enhance the accuracy and signal quality of the altitude readings.

The system is capable of measuring analog input signals, albeit with a resolution of only 10 bits. This resolution may limit the precision of the altitude measurements, as finer variations in altitude may not be captured effectively. As a response to this limitation, an additional circuit has been integrated onto the PCB to improve the measurement capabilities. This circuit likely includes a more sophisticated signal processing mechanism designed to refine the climb rate calculations, thereby providing a more responsive and accurate representation of altitude changes.

Furthermore, the PCB design includes an amplifier specifically for current measurements. This component is crucial for monitoring power consumption and ensuring that the data-logger operates within its specified electrical parameters. By implementing this amplifier, the system can accurately track current flow, which is essential for diagnosing potential issues and optimizing performance.

In summary, the finalized hardware design of the data-logger presents a compact solution with integrated altitude sensing and current measurement capabilities, albeit with limitations in analog signal resolution that are addressed through additional circuitry. This design aims to meet the needs of various applications while ensuring reliability and performance.The new data-logger software is not yet completely finished.
