DHT11 - Collecting data from multiple sensors to one PC

Other Hardware Sensors
1

Hi,

We are planning to buy multiple DHT11 sensors to monitor temperature and humidity of our sealed containers/bottles.

We also want to connect these sensors to ONE PC and collect data to the PC simultaneously.

I would like to ask if the above 2 objectives can be done? And if yes, is there any user manual about how to set up?

Thank you very much!

I would use DHT22 instead of DHT11 as the DHT22 is more accurate and has better range, although more expensive. Using a DHT library, set up an instance of DHT for each sensor (or an array of DHT objects). Read the sensors and build a comma delimited data stream with the temperature and humidity data. Send the stream over serial to a terminal application or custom program, on the PC, written in Processing or your favorite language.
