IC`S & SENSORS

What is IC ?

Stands For : Integrated Circuit

Integrated means to unify , to arrange the whole in a compact size.

Integrated Circuit is also called Chip.

TYPES OF ICs

Basically ICs are of three types. They are Digital IC , Analog IC and Mixed IC.

ICs , where both digital and analog systems are active are called mixed types of Ics.

IC Fabrication

Fabrication means manufacturing an IC.

According to the fabrication techniques, ICs can be parted in two types..

Monolithic IC and DIP

Moore`s Law

In the fabrication of ICs , a law called Moore`s law is followed.

According to Moore`s law, silicon wafers get increased twice after two years in the same area.

WHAT IS SENSOR

Sensor is an electronic system that senses.

If we have to read any parameter , we use sensors.

TYPES OF SENSORS

Sensors are of various types..

They are , touch sensor, heat sensor, IR sensor, Bio Sensor, Sound Sensor , Gas sensor etc.

SENSOR MAKING

Sensors can be made in various ways.

We can make different sensors for our purposes.

Sensors using ICs

We can make sensors with the help of different ICs.

Various microcontrollers (AVR, PIC etc.) , and timer ICs are used to make various sensors.

Applications In Daily Life

ICs are widely used in various circuits. Like, 555 timer is used in a huge field. In any complicated circuit, controllers are must.

In our daily life, sensors also have a great deal. Like gas sensors, water level sensors etc.

LET`S SEE AN EXAMPLE HOW WE CAN MAKE SENSORS WITH THE HELP OF IC`S.
