Sensors
Open Source Hardware

3. RASPBERRY Raspberry is a low cost computer with a credit-card sized.
Uses a standard keyboard and mouse.
It’s capable of doing everything you’d expect a desktop computer to do.
It has been used in a wide array of projects: from music machines and detectors to weather stations.
Example of a music machine:

4. RASPBERRY Differents models: Raspberry Pi Zero Raspberry Pi 1 Model A+
Raspberry Pi 1 Model B+
Raspberry Pi 2 Model B
Raspberry Pi 3 Model B
Raspberry Pi Touch Display
Raspberry Pi Case
...

5. RASPBERRY Pros Cons Cheap and portable
Super powerful with lot of memory and processing capabilities
Endless possibilities of what can be done using it
You need good knowledge of Linux
Closed source
Power hungry

6. ARDUINO Arduino is a printed circuit board.
Open source hardware/software.
Provides an IDE based on Processing, can support
C / C++.
The system provide sets of analog and
digital I/O.
Include an USB for loading programs.
It’s capable of doing everything

7. ARDUINO Pros Cons Low power architectures
Easy interfacing with sensors and data collection
Open-source
Variety for programming: IDE , python, ruby, C, etc.
Memory limitations and less powerful (compared to Raspberry)

8. Xbee
Xbee is the brand name of compatible radio modules boards from Digi International.
The module enable wireless communications between devices
Support P2P and P2MP communications.
Use different protocols:
Zigbee
DigiMesh
Proprietary protocols
Different models available, it can be adapted to any project.

9. Xbee
Differents models:

10. Xbee Pros Cons Portable Robust Connect to real world
Transmission frequency band: typically 900MHz or 2.4Ghz.
Can interact with Arduino, raspberry Pi…
Cheap
Power consumption vs integrated solution
Propitary protocols in some form factors
Cannot communicate between v1 & v2

11. SENSORS
Is an object whose purpose is to detect events or changes in its environment then provide and output.
A sensor is a type of transducer.
Transofrm non-electrial signals to electical signals.
Two types:
Digital Sensors
Analog Sensors

12. SENSORS
Some examples:

13. SENSORS Pros Cons Analog High performance
Reliably for complex applications
Digital
Easy to implement
Data conversion
Implementation more difficult

14. OPEN SOURCE HARDWARE (OSHW)
Allow everyone to download, modify, and share all schematics.
You can even sell your own versions of these products.
The original sharer gains feedback and potentially improvements on the design.
Companies have revenues of milion dollars, so OSHW is a good marketing strategy.
