# Ventilated Rear Panel for Air Quality Sensors

This is a remix of DanielB's CYD Modular Case with a ventilated honeycomb back panel, designed for air quality monitoring projects using the ESP32-2432S028 "Cheap Yellow Display".

## Why This Remix?

The original case is fantastic for general projects, but it has a solid closed back — not ideal for environmental sensors that need to sample the surrounding air.

This remix adds a honeycomb ventilation pattern that allows air to flow freely to your sensors while still protecting the electronics.

## Differences from Original

| Feature | Original | This Remix |

|---------|----------|------------|

| Back Panel | Solid/closed | Honeycomb ventilated |

| Air Flow | None | Full exposure |

| Use Case | General display projects | Air quality sensors |

## Ideal For

- SCD40/SCD41 — CO2, Temperature, Humidity sensors

- SGP40/SGP41 — VOC (Volatile Organic Compounds) sensors

- BME280/BME680 — Environmental sensors

- Any sensor that needs air exposure!

## Companion Project
