• If this product were to continue to be developed, what would the next steps be?

    One major design change would be to allow for more than two sensor nodes. This would require a dynamic address to be assigned to each node pragmatically (e.g., not using hard-coded values). This would enable us to sell to apartments, laundromats, etc.

    The GUI would need to have a long-term save ability, so that the program can be stopped and restarted without needing to reconfigure all settings. Another nice change would be to allow for the GUI to run in the background and not require a window.

    • What parts might be redesigned in your product?

    If this product went to market we would need to integrate our individual components onto one circuit board. The TI microcontroller and transceiver we are using is on a development board, but TI has the circuit diagrams showing how to build everything that is on the development board. 90% of the power supply circuit is all inside a premade component, and should be actually designed by us. It would be ideal to integrate the microcontroller, transceiver, power supply, and Hall Effect sensor all onto main board. This would majorly take this product to the next level of being able to make it smaller and make it easier to manufacture.

    • What functionality might be added?

    Adding functionality to ‘ping’ the Rx/Tx node pair independent of a cycle would allow for improved GUI notifications. We could show that the nodes are indeed connected and within transmission range.

    • What functionality seems unnecessary or is adding unneeded complexity?

    None. We set small tasks to complete, and met our project goals.
