Hello, This is in continuation to the previous two blogs of the series (How to start robotics at home)

Now talking in general about the sensors, Let me first explain to you their use and importance. We all use the words: Automatic/ Autonomous/ Self working robots. Now, these are sensors that make us feel their autonomous behavior.
Let me explain to you with an example,
For instance, if you see a robot car moving and then stops after someone comes in front of it. And no one is controlling, then you may feel that it is automatic. But there are sensors attached to the car and it is programmed like that.
For this particular case, Ultrasonic Sensors are attached which measure the distance from the object (or person) in front of it. Now, it is coded that if the distance is less than 5 cm (it's on you to change these values) from that object, then it must stop rotating the wheels of the robotic car.
Hence it's all about sensors in a robot that gives those unbelievable powers (just like a human).
Now let's study the types of sensors in detail
