Work completed

Updated project description to include low-power I²C CO₂ sensor and 10-year battery target (#co2 #lowpower #mppt #solar #lora #stm).
Added system architecture property with mermaid diagram.
Added sensor U5 (SCD41-D-R1).
Added power-gating load switch U6 (AP22916BCA4-7).
Added control transistor Q1 (2N7002KT1G).
Added I²C pull-ups R5, R6 (10 kΩ each).
Added decoupling caps C11, C12, C13, C14.
Completed all net connections for sensor power, ground, SDA/SCL and control GPIO.
Verified and set footprints & part types for all new components.
Configured PCB stackup to Standard 4 Layer and adjusted board size to 85 × 25 mm.
Defined CO₂ sensor mounting keep-out zone for user review.

Success criteria status

✅ Low-power CO₂ sensor integrated with I²C interface
✅ Schematic & PCB layout updated with all new components and proper routing
❌ Power budget calculation and battery capacity analysis to validate 10-year life—pending

Recommended next step Perform the detailed power consumption analysis and calculate required battery capacity to ensure a 10-year battery life target. (Next in flux-agentic-workflow: Power subsystem review)

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available. Standard capacitor values: 1.0pF 10pF 100pF 1000pF 0.01uF 0.1uF 1.0uF 10uF 100uF 1000uF 10,000uF 1.1pF 11pF 110pF 1100pF 1.2pF 12pF 120pF 1200pF 1.3pF 13pF 130pF 1300pF 1.5pF 15pF 150pF 1500pF 0.015uF 0.15uF 1.5uF 15uF 150uF 1500uF 1.6pF 16pF 160pF 1600pF 1.8pF 18pF 180pF 1800pF 2.0pF 20pF 200pF 2000pF 2.2pF 22pF 20pF 2200pF 0.022uF 0.22uF 2.2uF 22uF 220uF 2200uF 2.4pF 24pF 240pF 2400pF 2.7pF 27pF 270pF 2700pF 3.0pF 30pF 300pF 3000pF 3.3pF 33pF 330pF 3300pF 0.033uF 0.33uF 3.3uF 33uF 330uF 3300uF 3.6pF 36pF 360pF 3600pF 3.9pF 39pF 390pF 3900pF 4.3pF 43pF 430pF 4300pF 4.7pF 47pF 470pF 4700pF 0.047uF 0.47uF 4.7uF 47uF 470uF 4700uF 5.1pF 51pF 510pF 5100pF 5.6pF 56pF 560pF 5600pF 6.2pF 62pF 620pF 6200pF 6.8pF 68pF 680pF 6800pF 0.068uF 0.68uF 6.8uF 68uF 680uF 6800uF 7.5pF 75pF 750pF 7500pF 8.2pF 82pF 820pF 8200pF 9.1pF 91pF 910pF 9100pF #generics #CommonPartsLibrary
