QR Code Door Unlock Prototype (with off the shelf components) -- 2
Budget: $15 – $25 USD
We are seeking a skilled freelance Electronics Integration Engineer to build the hardware foundation for a prototype system that unlocks a door by scanning a QR code. You will integrate and test key electronic components, including an ESP32 microcontroller, an electronic door lock, a connectivity module (cellular/Wi-Fi). You will be responsible for the physical connections, power system, and initial hardware validation. Note: I already have the mobile app (to scan the QR code on the door) and I will own the software (or firmware or however you want to call it).
It is a solenoid lock. it is commercially available. no custom work needed on that electronic lock
Key Responsibilities:
1. Physically integrate electronic components (ESP32, specified electronic lock, connectivity module, QR code scanner) based on provided specifications.
2. Design and implement a reliable 12V power distribution system.
3. Create clear wiring diagrams and interconnection documentation.
4. Perform thorough hardware testing and debugging to ensure all components function correctly.
5. Collaborate with the software development team for seamless hardware-software interaction.
6. Advise on component mounting and physical integration.
The idea is, I will write the embedded logic for the esp32, which sends lock/unlock commands to the solenoid lock. Need support in the microcontroller, connectivity, other sensor assembly, power distribution (from a 12V battery). I will be writing all the code and will upload the microcontroller. I need support in component assembly.
I have a physical prototype (a portable door unit). not sure how i can take the final pcb product but open to working with freelancers remotely.
