Arduino Cabin Comfort Monitor for Cruise Ship Use (Cove Balcony Inspired Project)

[oliver56]

Hey everyone,

I’m designing an Arduino-based monitoring system for small cabin spaces like those on cruise ships. It’s inspired by cove balcony cabins on Carnival cruise ships, which are semi-enclosed and often more humid.

The plan is to:

Use a DHT22 sensor to measure temp and humidity.

Add an MQ-135 for air quality.

Display data on a small OLED.

Possibly log to SD card or transmit via ESP8266.

This would be helpful in cabins to ensure comfort or detect mold-prone conditions.

Does anyone have suggestions for efficient power consumption or compact enclosures for travel-sized projects?

Thanks in advance!

What power is available in the small cabin?

That sounds like a large undertaking. If you are using cabin power you probably will not have to worry about that. As for the enclosure from the apparent volume you could use a custom enclosure with your project on a custom PCB.

Do not use the MQ-135. Just use temperature and humidity to calculate "comfort" level.

this is what cove balcony cabins look like on Carnival ships:

Ah, pretty much like this
