Using a combination of a cloud-based data visualisation service and multiple Raspberry Pi computers you can easily monitor data from each Pi concurrenlty on the one screen - ideal for monitoring various sensors placed in multiple sites. A few years ago this may have seemed impossible or very expensive, however nothing could be further from the truth.
The people from Initial State - "a technology startup helping engineers capture and understand product data" - have produced a neat tutorial that explains how to use popular DS18B20 digital temperature sensors each with a Raspberry Pi, and how to send the data back to their cloud service. Both hardware and software requirements are explained which will have your system working very quickly, and leave you with a neat and useful dashboard - for example:

If you're interested in measuring termperature with a reliable sensor - consider using our TEMP: DS18B20-based temperature sensor module:
The TEMP: uses the Dallas DS18B20 1-wire digital temperature sensor, with a wide measurement range of -55 to +125°C at an accuracy of +/- 0.5°C. For more information, tutorials and to order - visit the TEMP: page.
