Electronic Control Unit Design

I need an electronic control unit designed for an AC-powered system. The control unit should be designed within specific, yet-to-be-defined dimensions, and must handle outputs with a current capacity of 5A.

Key tasks include:
- Designing, simulating & Testing the electronic circuit for the control unit, motion sensor & Light sensor
- Implementing timer functionality with five operating modes ( 1, 3, 5, 10, alaways on)
- Developing an input interface for motion and light sensor signals
- Integrating an automatic disable function for the motion sensor based on light sensor input
- Designing a mechanical rotary switch for time adjustment
- Testing various control methods (light sensor, motion sensor + timer, mechanical button+ timer)
- Ensuring sensor functionality in both standalone and control unit modes.
- Creating a complete wiring diagram
- Verifying current capacity for each output line
- Preparing a final specification document with test results

Ideal skills and experience:
- Expertise in electronic circuit design
- Experience with timer circuits and sensors
- Proficiency in wiring diagrams and current capacity verification
- Strong documentation skills
