UNIT IV - IoT PHYSICAL DEVICES & ENDPOINTS
IoT DEVICE
IoT DEVICE
• A "Thing" in Internet of Things (IoT) can be any object that has a unique
identifier and which can send/receive data (including user data)over a
network (e.g. smartphone, smart TV, computer, refrigerator, car,etc.).
• IoT devices are connected to the Internet and send information about
themselves or about their surroundings (e.g. information sensed by the
connected sensors) over a network (to other devices or servers/storage) or
allow actuation upon the physical entities/environment around them
remotely.
IoT Device Examples
• A home automation device that allows remotely monitoring the status of
appliances and controlling the appliances.
• An industrial machine which sends information abouts its operation and
health monitoring data to a server.
• A car which sends information about its location to a cloud-based service.
• A wireless-enabled wearable device that measures data about a person
such as the number of steps walked and sends the data to a cloud-based
service
BASIC BUILDING BLOCKS OF AN IOT DEVICE
Sensing:
• Sensors can be either on-board the loT device or attached to the device.
• IoT device can collect various types of information from the on-board or
attached sensors such as temperature, humidity, light intensity, etc.
• The sensed information can be communicated either to other devices or
cloud-based servers/storage.
Actuation:
• IoT devices can have various types of actuators attached that allow taking
actions upon the physical entities in the vicinity of the device.
• For example, a relay switch connected to an IoT device can turn an
appliance on/off based on the commands sent to the device.
BASIC BUILDING BLOCKS OF AN IOT DEVICE
Communication:
• Communication modules are responsible for sending collected data to
other devices or cloud-based servers/storage and receiving data from other
devices and commands from remote applications.
Analysis & Processing:
• Analysis and processing modules are responsible for making sense of the
collected data.
• Once the entire data transmits to the platform, functions are performed on
this data in order to process the data and send back necessary outputs. In
other words, data analysis must take place.
• This step is the most important step in IoT technologies. The analysis
must happen at a quick rate to provide better results.

RASPBERRY PI BOARD
• Raspberry Pi is a low-cost mini-computer with the physical size of a
credit card.
• Raspberry Pi runs various flavors of Linux and can perform almost all
tasks that a normal desktop computer can do.
• In addition to this, Raspberry Pi also allows interfacing sensors and
actuators through the general purpose I/O pins.
• Since Raspberry Pi runs Linux operating system, it Supports Python
"out of the box”.
RASPBERRY PI BOARD
RASPBERRY PI BOARD
Processor & RAM:
• Raspberry Pi is based on an ARM processor. The latest version of
Kaspbery Pi (Model B, Revision 2) comes with 700 MHz Low Power
ARMI176JZ-F processor and 512 MB SDRAM.
USB Ports:
• Raspberry Pi comes with two USB 2.0 ports. The USB ports on
Raspberry Pi can provide a current upto 100mA.
• For connecting devices that draw current more than 100mA, an
external USB powered hub is required.
RASPBERRY PI BOARD
Ethernet Ports:
• Raspberry Pi comes with a standard RJ45 Ethernet port. You can connect an
Ethernet cable or a USB Wifi adapter to provide Internet connectivity.
HDMI Output:
• The HDMI port on Raspberry Pi provides both video and audio output.
• You can connect the Raspberry Pi to a monitor using an HDMI cable. For
monitors that have a DVI port but no HDMI port, you can use an HDMI to
DVVI adapter/cable.
Composite Video Output :
• Raspberry Pi comes with a composite video output with an RCA jack that
supports both PAL and NTSC video output.
• The RCA jack can be used to connect old televisions that have an RCA
input only.
RASPBERRY PI BOARD
Audio Output:
• Raspberry Pi has a 3.5mm audio output jack. This audio jack is used for
providing audio output to old televisions along with the RCA jack for video.
• The audio quality from this jack is inferior to the HDMI output. GPIO Pins
Raspberry Pi comes with a number of general purpose input/output pins.
• There are four types of pins on Raspberry Pi - true GPIO pins, I2C interface
pins, SPI interface pins and serial Rx and Tx pins.
Display Serial Interface (DSI):
• The DSI interface can be used to connect an LCD panel to Raspberry Pi.
Camera Serial Interface (CSI):
• The CSI interface can be used to connect a camera module to Raspberry Pi.
