What is Sensor Technology?
Sensor technology is the use of devices called sensors that can detect changes in the environment and send information to machines or computers. These changes can be things like temperature, light, movement, pressure, sound, or distance.
In simple words, sensors are like the senses of machines. Just like humans use eyes, ears, and skin to feel the world, machines use sensors to understand what is happening around them.

How Does Sensor Technology Work?
Sensor technology works in a simple step-by-step process:
A sensor detects a change in the environment.
It collects data about that change.
The data is sent to a system or device.
The system processes the data.
The machine reacts based on the information
For example, a motion sensor in a light detects movement and turns the light on automatically.
Types of Sensors
There are many different types of sensors used in daily life and industries:
Temperature Sensors
These sensors measure heat or cold. They are used in air conditioners, refrigerators, and weather systems.
Motion Sensors
They detect movement. They are used in security systems and automatic doors.
Light Sensors
These sensors detect light levels. They help control screen brightness in phones and street lights.
Pressure Sensors
They measure pressure in tyres, machines, and medical devices.
Proximity Sensors
These sensors detect how close an object is without touching it.
Gas Sensors
They detect harmful gases in factories and homes.
