MedMinder Dispenser

A fail-safe medication-adherence system pairing physical dispensing with caregiver visibility.

Build a dependable dispenser for elderly care that prompts the right dose on schedule and keeps caregivers informed — even when the user forgets or the network drops. Consumer pill reminders lacked hardware fail-safes and caregiver accountability.

• Dosing errors are safety-critical — zero tolerance
• Intermittent home Wi-Fi and BLE environments
• Caregiver oversight without invasive UX

MCU dispenser + RTOS scheduler → BLE/Cloud sync → Caregiver app + Admin panel.

• RTOS owns dose schedule and physical dispense confirmation
• Sync layer batches adherence events with offline queue
• Caregiver app and admin panel share adherence state model

Engineered low-power RTOS scheduling that triggers timed audio-visual prompts, with confirmation tracking synced to caregiver app and oversight panel.
