Software Requirements Specification

SRS 01 - The software shall read real-time data from the weight sensor via the I²C interface to track water consumption.

• Fixed
• The software reads real-time data from both the weight sensor via ADC and the humidity & temperature sensor via the I²C interface.

SRS 02 - The software shall calculate the amount of water consumed after each drinking action and log the timestamp.

• Fixed
  • The weight sensor could accurately detect the mass change of the water cup after each time the cup is removed from the coast.
  • Removed timestamp logging.

SRS 03 - The system shall send drinking data (time and amount) to the mobile app via Wi-Fi after each drinking action.

• Fixed
  • Removed timestamp from the payload.
  • Drinking amount is sent; see the Node-RED dashboard below for confirmation.
  

SRS 04 - The software shall receive hydration goal settings from the mobile app and update the device's behavior accordingly.

• Finished
  • The system adjusts the hydration interval according to the humidity and temperature data received from the sensor.

SRS 05 - The system shall trigger LED and buzzer reminders when a hydration interval is missed.

• Partially finished
  • The system now only triggers buzzer reminders; the LED strip was removed due to its complexity and time constraints.
  See the demo video for evidence.

SRS 06 - The system shall send push notifications via the app when a hydration reminder is triggered.

• Abandoned
  • The buzzer alone is deemed sufficient to alert the user to drink water.

SRS 07 - The software shall enter a low-power mode when idle to conserve battery life.

• Abandoned
  • The system’s baseline consumption is low enough that additional low-power modes were not implemented.
