IoT DEVICES (hardware) Raspberry Arduino Xbees Sensors Open Source Hardware

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: https://www.maketecheasier.com/raspberry-pi-music-machine/ https://www.raspberrypi.org/blog/

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 ...

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

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 https://www.arduino.cc/#/

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)

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 802.15.4 DigiMesh Proprietary protocols Different models available, it can be adapted to any project.

Xbee Differents models:

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

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

SENSORS Some examples:

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

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.
