Updated project description
Defined system architecture
Added U4 as U4 (3.3 V LDO)
Added Q1 as Q1 (MOSFET heater switch)

Remaining tasks

Add major ICs: MICS-4514 sensor (U1), ESP32-WROOM-32 module (U2), TI ADS1115 ADC (U3)
Review power subsystem and add decoupling capacitors for LDO, ESP32, ADC
Add I²C pull-up resistors (4.7 kΩ) and RC filter components (10 kΩ + 100 nF) for each ADC input
Place connectors/test points and define all nets (VCC logic, PWM, heater, sensor outputs, ADC inputs, I²C)
Run schematic ERC/DRC checks and verify designators and net names
Prepare PCB layout: assign footprints, define stackup, board outline, power planes, mounting holes

Success criteria Not yet met: the schematic is incomplete (major ICs missing, no filters or pull-ups, nets unconnected) and ERC/DRC has not been performed.

Next step Proceed to Step 3 of the workflow: review the power subsystem and add all supporting passive components (decoupling caps, pull-ups, RC filter parts).
