Questions & Answers

Q: What is the primary function of the smart name plate?

The smart name plate serves as an efficient communication tool to indicate an individual's status and location in an office setting, allowing others to easily determine if one is busy, available, or out. It does this through an E Ink display that can be updated via Bluetooth from a smartphone.

Q: How is the battery life managed for the name plate?

The name plate uses a 3500 mAh battery, estimated to last around seven days on a single charge based on its power consumption. The device consumes approximately 50 mA per hour during active use, allowing for seamless operation throughout a typical workweek without needing frequent charging.

Q: Why was an ESP32 microcontroller chosen for this project?

The ESP32 microcontroller was chosen due to its affordability and built-in battery management circuit. Its capabilities support Bluetooth connectivity, making it perfect for real-time updates, and it efficiently manages power consumption while operating the low-power E Ink display.

Q: What challenges were faced when measuring battery voltage with the ESP32?

The ESP32's ADC has limitations with non-linear readings at higher voltages. To accurately measure the battery's voltage, a voltage divider was constructed to ensure the input to the ADC remains below 2.4V, implementing a safety margin to deliver reliable and accurate voltage readings.

Q: Can additional features be implemented in this smart name plate?

Yes, the Arduino code can be modified to include additional features, such as updating the name and phone number displayed on the E Ink screen. These features can be managed dynamically via Bluetooth, making the device even more functional and personalized as needs change.

Q: How does the RGB LED enhance the functionality of the name plate?

The RGB LED component allows for a visual representation of the user's status through color changes. For instance, it can glow green when available and red when busy, providing immediate recognition for anyone approaching, thus enhancing the communication aspect of the name plate.

Q: What design considerations are mentioned for the enclosure of the device?

The enclosure was 3D printed, and adjustments were made to improve magnetic strength for sticking to surfaces. The user noted that while the design fit reasonably well, further iterations could refine aspects like hole placements for added functionality and aesthetic appeal.
