The project is currently empty: no components, nets, schematic, or PCB layout have been created yet. I can’t continue executing design work right now because there are no available ACUs for AI actions.
What remains to be done:
- Define the product architecture: temperature sensor + motion sensor + controller + relay output + power input.
- Choose parts, likely an ESP32 or low-power MCU, a digital temperature sensor, a PIR/mmWave motion sensor, relay driver, protection diode, and automotive power protection.
- Create the schematic, wire the relay output, and add power regulation suitable for a car battery environment.
- Add firmware notes for the trigger logic: only activate relay when temperature is above threshold and pet/movement is detected.
- Later, make the PCB layout and validation/bring-up plan.
When ACUs are available, I can build the full schematic for this pet-in-car temperature and movement detector.
