2.  Earthquake is commonly said to be a natural disaster which is also
known as tremor .
 The sudden shake in the surface of the earth, which shutters down
the buildings and kills thousands of human lives.
 Thereby by predicting the surfaces shake earlier by means of
sensors that may warn public earlier.
 By the theory that the S waves are the first attack wave from the
surface and then the P waves attack the surface latter that brings the
strongest shake then the S wave.
 Hence the public is warned earlier in few minutes or seconds before.
 The IOT is the network it connects the internet connected objects to
form a network and hence the alert message is send to the public is
more accurate way by IOT.

6.  Flux sensor which is 2.2 inches in length. This sensor works by
bending the sensor itself.
 As the sensor is being flexed or bent, the resistance across the
sensor increases. The greater the angle of bending, the greater the
resistance.
 This can be tested with multimeter. The resistance of the flex sensor
changes when the metal pads are on the outside of the bend.

7.  This is a force sensitive resistor with a square, 1.75x1.5", sensing
area.
 This FSR will vary its resistance depending on how much pressure
is being applied to the sensing area. The harder the force, the lower
the resistance.
 When no pressure is being applied to the FSR its resistance will be
larger than 1MΩ.
 This FSR can sense applied force anywhere in the range of 100g-
10kg.

8.  This basic Vibration sensor can be used in anti-theft devices,
electronic locks, mechanical equipment vibration detection, sound
gesture application and counts vibration sensor occasions.
 These vibration levels could be given to any controller/processor
and necessary decisions could be taken through it.
 Module triple output mode, digital output simple, analog output
more accurate, serial output with exact readings.
 Resistance Decreases when Vibration Increases near the Sensor
places

9.  XBees are hugely popular wireless transceivers for a number of
reasons.
 They’re flexible they send and receive data over a serial port, which
means they’re compatible with both computers and microcontrollers
(like Arduino).
 They are highly configurable you can have meshed networks with
dozens of XBees, or just a pair swapping data.
 You can use them to remotely control your robot, or arrange them
all over your house to monitor temperatures or lighting conditions in
every room.

10.  NodeMCU is a Micro controller and an open source IoT platform. It
includes firmware which runs on the ESP8266 WiFi SoC from
Espressif, and hardware which is based on the ESP-12 module.
 The ESP8266 module is a IoT device consisting of a 32-bit ARM
microprocessor with support of WIFI network and built-in flash
memory.
 This architecture allows it to be programmed independently, without
the need of other microcontrollers like the Arduino.

11.  63 vertical columns on top and 63 columns below.
 Each column has 5 connected holes.
 There are also 4 rails for power and ground running horizontally.
