What Is Raspberry pi?
A Raspberry Pi is a credit card-sized computer originally
designed for education.
It is a motherboard containing different slots like USB
port, Audio jack, memory slots, and Ethernet port etc.
It is slower than a modern laptop or desktop but is still
a complete Linux computer and can provide all the
expected abilities that implies, at a low-power
consumption level.
Price of Raspberry pi is in between 5$-35$(350Rs-
2500Rs)

How did the Raspberry Pi get its name
[ fruit name + python]
A lot of computer companies were named after fruit. There's
Tangerine Computer Systems, Apricot Computers, and the old
British company Acorn, which is a family of fruit. Pi is because
originally we were going to produce a computer that could only
really run Python. So the Pi in there is for Python.

Launched:-
 In February 2012 Raspberry pi 1 model B (Basic)
 In April 2014 Raspberry Pi 1 Model B+ (credit-card sized)
 Improved A+ and B+ models were released a year later.
 In February 2015 Raspberry Pi 2 (added more RAM )
 In November 2015 Raspberry Pi Zero (General-purpose input/output (GPIO))
 in February 2016 Raspberry Pi 3 Model B released (on-board Wi-Fi, Bluetooth and
USB Boot capabilities)
 February 28, 2017, the Raspberry Pi Zero W (identical to the Raspberry PI Zero, but
has the Wi-Fi and Bluetooth functionality)

HowIt Works
 An HDMI television or monitor:
 You’ll need to connect your Raspberry Pi to a display, which means you’ll need an HDMI-enabled screen of
some kind. Or HDMI supportable TV. And connect it
 A USB keyboard and mouse:
 In order to control your Pi, you’ll need a keyboard and mouse. At this point, pretty much any USB
keyboard and mouse will work.
 An 8GB Micro SD card and card reader:
 8GB card for this. The Samsung EVO+ Class 10 cards like this one are best. If your computer doesn’t have a
card reader, then you need a hard drive, you install the Raspberry Pi’s operating system on a Micro SD
card. You’ll want at least an memory card one like this will do.
 A power supply:
 The Raspberry Pi is powered by a micro USB, much like the one you’ve likely used for your phone. Since
the Pi 3 has four USB ports, it’s best to use a good power supply that can provide at least 2.5A of current.

Raspberry pi in IOT
Using Raspberry pi we can create various sensor of IOT
Examples
1. IoT DoorBell: This projects shows an automatic door bell which sends an sms or email.Thus the
owner can easily monitor from anywhere if someone knock his door.
2. Review on Temperature & Humidity Sensing using IoT: Here is the temperature and humidity
sensing using IOT. This is a novel method using raspberry pi scriptung.
3. Home Automation Using Internet of Things: Internet of Things (IoT) allows us to implement home
automation system that can be controlled remotely through internet. The proposed system can
monitor different parameters like gas, light, motion detection, temperature, etc. using the sensor
data and also trigger a process according to the requirement. The data from the sensors are
uploaded to a cloud server and this data can be used to analyze the parameters.
