I'm looking for an Arduino board that include this sensors out of the box:

  • CO2
  • Humidity
  • Noise
  • Temperature

I've found here Using the Waspmote Sensor Board something that could be enough, but I'm searching for more options.

I did a lot of searches on the Internet without good results.

Any suggestions?

For humidity and temperature you can plug the DHT11 or DHT22 to your arduino. DHT11 is cheaper but you'll get a more precise value with DHT22.

For noise you have ready made PCB like these : here You'll only have to plug it to GND, 5V and analog input.

For CO2 this is more complicate. There is a cheap but very unprecise option, using a MQ135 sensor, here is a tutorial: here Otherwise there are better sensors like the K30 but they are much more expensive.
