2. Arduino
• Arduino is an open source, computer
hardware and software company,
project, and user community that
designs and manufactures
microcontroller kits for building digital
devices and interactive objects that can
sense and control objects in the
physical world.

3. IOT
The Internet of things (IoT) is the inter-networking of
physical devices, vehicles (also referred to as "connected
devices" and "smart devices"), buildings, and other items
- embedded with electronics, software, sensors,
actuators.
Network connectivity that enable these objects to collect
and exchange data. In 2013 the Global Standards
Initiative on Internet of Things (IoT-GSI) defined the IoT
as "the infrastructure of the information society.
The IoT allows objects to be sensed or controlled
remotely across existing network infrastructure, creating
opportunities for more direct integration of the physical
world into computer-based systems, and resulting in
improved efficiency, accuracy and economic benefit in
addition to reduced human intervention.

4. Cont …
When IoT is augmented with sensors
and actuators, the technology becomes
an instance of the more general class
of cyber-physical systems, which also
encompasses technologies such
as smart grids, smart homes, intelligent
transportation and smart cities.
Each thing is uniquely identifiable
through its embedded computing
system but is able to interoperate
within the
existing Internet infrastructure. Experts
estimate that the IoT will consist of
almost 50 billion objects by 2020.

5. Micro Controller
• ATmega8 is a 8-bit microcontroller based on
the AVR RISC architecture
• By executing powerful instructions in a single
clock cycle, the ATmega8 achieves throughput
approaching 1 MIPS per MHz

6. Cont....
• In order to maximize performance and
parallelism, the AVR uses a Harvard
architecture- which separates memories and
buses for program and data
• Instruction in program memory are executed
with single level pipelining
• This concept enables instructions to be
executed in every clock cycle

7. FEATURES High-performance 8 bit Microcontroller
Up to 16 MIPS Throughput at 16 MHz
32 x 8 General Purpose Working Registers
Six ADC channels in PDIP package
Internal Calibrated Oscillator

8. List of
Sensor’s
IR Sensor
DHT level – Temperature Sensor
HC 05 – Bluetooth Device Sensor

10. WORKING
• IR sensor works on the
principle of emitting IR rays
and receiving the reflected
ray by a receiver (Photo
Diode).
• IR source (LED) is used in
forward bias.
• IR Receiver (Photodiode) is
used in reverse bias.

11. VOLTAGE
COMPARATOR
• A Comparator is a device which compares
two voltages or currents and switches its
output to indicate which is larger.
• Comparator is an Op-amp.
