Develop IoT Maintenance Tracking Device
Budget: $250 – $750 USD
Smart Maintenance Device – Developer Brief
⸻
PROJECT OVERVIEW
We are developing a compact, battery-powered device designed to track usage patterns of a mechanical system in a residential setting. The device will record motion-based events and transmit that data wirelessly to a mobile application for users to monitor system health and receive alerts.
⸻
WHAT WE NEED DEVELOPED
1. Hardware & Firmware
• Microcontroller with BLE capability (ESP32 family preferred)
• Motion sensor integration (accelerometer/gyroscope)
• Power-efficient firmware to track defined motion events
• BLE broadcasting: device ID and event counter
• Optional: Wi-Fi or cloud sync capability
2. Mobile App (iOS + Android)
• Cross-platform (Flutter or React Native)
• BLE connection and QR code scan to identify devices
• Display tracked event count and general system health
• Optional profile creation for remote access and notifications
3. Cloud Backend (Firebase/Supabase preferred)
• UID-based device tracking
• User profile integration and alert triggers
• Basic dashboard/API for data access and customer management
4. Admin Dashboard (Web)
• View multiple tracked units
• Manage alerts and user profiles
• Optional device claim/unclaim functionality
5. Enclosure & Hardware Fit
• Design a custom plastic enclosure to house ESP32 board, motion sensor, and battery
• Must allow for:
• Clean adhesive-based mounting to flat surfaces
• QR code visibility on external face
• Optional screw or snap-fit access to internal components
• Compact form factor matching provided mockups
• Deliverables include:
• STL files for 3D printing
• Source files for revisions and manufacturing prep
⸻
FUNCTIONAL HIGHLIGHTS
• Device counts specific physical motions over time
• Users can scan a QR code to view device data
• Optional profile creation for remote access and alert management
• Admin interface for technicians or companies managing devices
⸻
DELIVERABLES
• Programmed microcontroller firmware
• Full app source code and wireframes
• Backend setup and API endpoints
• Admin panel for internal use
• STL files + editable CAD for enclosure
⸻
TEAM NEEDS
• Firmware engineer (ESP32/sensor filtering)
• App developer (BLE + UI integration)
• Backend/database setup and sync logic
• Hardware designer or industrial prototyper (for casing)
⸻
NEXT STEPS:
Interested developers should be prepared to:
• Sign an NDA
• Review technical direction and project scope
• Provide timeline and examples of relevant past work
