SENSOR TYPES AND ITS WORKING

 IOT - SENSOR AND ITS WORKING

The word "Automation" has begun already. It evolved in our daily life too. Most of things that we use now can be automated.

 For designing and knowing the work, we need to know the sensor types and it working. Even daily usage of mobile contains sensors like hall sensor, proximity sensor, accelerometer sensor, touch screen, microphone etc.,

There are plenty of sensors available and each have different characteristics,

Sensor definition:

The sensor can be defined as a device which can be used to sense/detect the physical quantity like force, pressure, strain, light etc and then convert in to desired output like the electrical signal to measure the applied physical quantity.

                                   (input)----> sensor---->Signal detecting---->(output)

Various sensors have different operating ranges which should be considered while working with it else the sensor may get damaged permanently.

TYPES OF SENSORS:

IR LED sensor:

  • It is also called as IR Transmitter.
  • It is used to emit Infrared rays.
  • It sense/detect objects through its rays.
TEMPERATURE sensor:
  • A thermistor can be used to detect the variation in temperature.
  • It has a negative temperature coefficient that means when the temperature increases the resistant decreases.
FORCE Sensor:
  •  A force sensor is used to detect pressure when a load is applied.
  • It is used to calculate the amount of pressure that an airplane wing can with stand and it is also used to measure the number of vehicles allowable on a particular road etc.
HALL Sensor:
  • It works on the Hall effect.
  • It is used to detect the magnetic field and gives output in terms of voltage.
  • Few smartphone contain this sensor and is used for turning off the screen.
  • Door alarm is one of the application used by hall sensor.
ULTRASONIC Sensor:
  • Most widely used sensor nothing but the range of the frequencies.
  • It is used to calculate the distance between the ultrasonic transmitter and the target and also used to measure the velocity of the target.
  • Avoiding obstacles for the automated cars, moving robots are some of the applications.
  • A mosquito can sense the ultrasonic sounds, so ultrasonic waves can be used as mosquito waves can be used as mosquito repellent.
Other types of sensors are:
Flame Sensor, Gas Sensor, Tilt Sensor, PIR Sensor, Touch Sensor, Sound Sensor... Etc.,



Tips to be productive:
  • Get enough sleep.
  • Rise early
  • Meditate daily
  • Focus on most important tasks first.
  • Cultivate deep work.

ETHICAL HACKING

  ETHICAL HACKING E thical H acking is a structured hacking performed to expose vulnerabilities in a system, using a tools and techniques with organizations knowledge.  The act of hacking is defined as the process of finding a set of vulnerabilities in a target system and systematically exploiting them. Ethical hacking as a discipline discerns itself from hacking by adding a vital element to the process. The process becomes a legal activity and since the hacker takes permission prior to hacking into system, it is legally made sure that he has no malicious intent. This is normally performed by making the ethical hacker sign contracts that legally bind him to work towards the improvement of the security of the company. ETHICAL HACKER: An Ethical hacker is a computer security specialist, who hacks into a system with the consent or permission of the owner to disclose vulnerabilities in the security of the system in order to improve it.  Types of Hackers: White hat hackers Bla...

Linux OS introduction

 LINUX OPERATING SYSTEM Linux Introduction:   L INUX is an operating system or a kernel distributed under an open-source license. It is one of popular version of UNIX operating system. Linux was designed considering UNIX compatibility Its functionality list is quite similar to that of UNIX. Components of Linux System: Linux OS has primarily three components; 1. Kernel: It is the core part of Linux. It is responsible for all major activities of this operating system. It consists of various modules and it interacts directly with the underlying hardware. 2. System Library: These libraries implement most of the functionality of the operating system and do not requires kernel module's code access rights. 3. System utility: These programmes are responsible to do specialized, individual level tasks. Basis Features: Some of the features of Linux OS are: Portable Open source Multi-user Multiprogramming Hierarchical file system Security... etc., courtesy: Pinterest Benefits of Using L...

Cloud computing on AWS

  CLOUD COMPUTING ON AMAZON WEB SERVICES(BASICS) AWS(Amazon Web Service) is a cloud service platform that enables users to access on demand services like database storage, virtual cloud server, networking et., AWS is a platform that offers flexible, reliable, scalable, easy-to-use and cost-effective cloud computing solutions. AWS is a combination of three services: Infrastructure as a service(IaaS) platform as a service (PaaS) software as a service(SaaS) History of AWS: AWS service has been created and discovered its cloud platform in the year 2006. In 2012 holds first customer event, in 2015 it reveals revenues achieved of nearly $4.8 billion and In 2019 offers nearly 100 cloud services. Some of the important AWS services: Compute storage  Database Networking Messaging  Management tools Some of the Companies using AWS services: Instagram Netflix Pinterest Dropbox Talk box Application of AWS services: Social Networking Search Engines Storage, backup Application hosting We...
