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.
