+ <p style="justify-content: center"><strong> An input device responds to changes in the environment and produces a suitable electrical signal for processing in an electronic circuit.
+ In all input devices, other forms of energy are transformed into electrical energy.The sensor is an element that produces signals relating to the quantity that is being measured.
+ According to Instrument Society of America, “a sensor is a device that provides usable output in response to a specified quantity which is measured.†The word sensor is derived from the original
+ meaning ‘to perceive.’ <br>
+ Sensors are devices that perform input function in a system as they ‘sense’ the changes in a quantity. The best example of a sensor is mercury thermometer. Here the quantity that is being measured
+ is heat or temperature. The measured temperature is converted to a readable value on the calibrated glass tube, based on the expansion and contraction of liquid mercury.</strong> </p>

+ <h4 id="criteria" style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong>Criteria to Choose a Sensor</strong> </h4>
+ <p style="justify-content: center"><strong> The following are certain features that are considered when choosing a sensor. <br>
+Type of Sensing: The parameter that is being sensed like temperature or pressure. <br>
+Operating Principle: The principle of operation of the sensor. <br>
+Power Consumption: The power consumed by the sensor will play an important role in defining the total power of the system. <br>
+Accuracy: The accuracy of the sensor is a key factor in selecting a sensor. <br>
+Environmental Conditions: The conditions in which the sensor is being used will be a factor in choosing the quality of a sensor. <br>
+Cost: Depending on the cost of application, a low cost sensor or high cost sensor can be used. <br>
+Resolution and Range: The smallest value that can be sensed and the limit of measurement are important. <br>
+Calibration and Repeatability: Change of values with time and ability to repeat measurements under similar conditions. <br>

+ <h4 id="brief" style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong>A Brief Introduction to Smoke Sensor</strong> </h4>
+ <p style="justify-content: center"><strong> There are two types of smoke detectors. Optical or Photoelectric smoke detectors and Ionization smoke detectors. <br>
+Optical smoke detectors consists of a light source like LED and a light detector like photocell.
+The photocell conducts as long as the light falls on it. When there is smoke, the light from the source is interrupted and the photocell doesn’t conduct. <br>
+Ionization smoke detectors consists of two electrodes and an ionization chamber filled with ions. When there is no smoke, the ions move freely and the electrodes conduct normally.
+In the presence of smoke, the chamber is filled with smoke and interrupts the movement of ions. The electrodes do not conduct anymore. Depending on the type of sensor and manufacturer, the conductivity conditions may change but the idea remains the same.

+ Here in India, the Govt. of India is announced the Lockdown of 21 days. As per the schedule of Fab Academy, the assignment number 8,9 & 10 is between this period.
+I am at home, so i dont have lab acessed for this assignment right now. So i am trying to connect the sensor on arduino board on TinkerCad software and read it using serial monitor.Here i am trying three different sensor
+in TinkerCad 1. Smoke sensor 2. PIR (motion) sensor 3. Light Sensor. In my final project i am using smoke sensor. so i have develop the board for the smoke sensor module using ATtiny 44 IC in Eagle software.
+When i went to lab, then i will develop the board on milling machine and assembling the all components and in an actual i will read the data. </strong> </p>

+PIR sensors detect general movement, but do not give information on who or what moved. For that purpose, an active IR sensor is required.
+PIR sensors are commonly called simply "PIR", or sometimes "PID", for "passive infrared detector". The term passive refers to the fact that PIR devices do not radiate energy for detection purposes.
+They work entirely by detecting infrared radiation (radiant heat) emitted by or reflected from objects. <br> There are the 3 pins are given to sensor. One is power, second is ground and third is signal. LED is also connected to
