Introduction Commercial Solutions
Commercial Solutions
Advantages
Highly integrated environments
Sensors and controllers nicely packaged
Support
Wide range of sensors available
Disadvantages
Expensive for small Data-Centers (≤ 10 Racks?)
APC: ∼ 370e+ sensors (> 30e each)AVTech: ∼ 110e+ 1 sensor (> 25e)ServersChecks: ∼ 180e+ 1 sensor (> 45e)Domodesk: ∼ 480e+ sensors
Expanding them requires, some times, to buy from the same vendor

Introduction Open hardware/Software solutions
Open hardware/Software solutions
Pros
They can be highly integrated environments
Highly customizable by the user
Affordable.
Wide range of sensors available
Can be bought as a full solution
Cons
Lots of work if DIY:
Software: Arduino, sensors and control programsHardware: some soldering
Lack of support if DIY
Could be expensive if bought from a vendor

Introduction Arduino
Arduino
It is a simple microcontroller board and adevelopment environment
It was designed to be:
InexpensiveCross-platformTo have a Simple, clear programming environmentOpen source and extensible softwareOpen source and extensible hardware
Its capabilities can be extended with the use ofshields, that is, boards that can be plugged on topof the Arduino.
