Arduino + CO2 + humidity + noise + temperature sensors on one board

Question

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?

Answer 1

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.
