Input Devices in dangerous places:

People use special input devices in dangerous places to stay safe. These devices help them see, measure, and control things from far away. Sensors check heat, gas, and radiation. Cameras help people see without going near danger. Robots do risky jobs like removing bombs or handling chemicals. Drones fly to take pictures and find people in emergencies. Touchscreens and keypads help control machines safely. These devices protect people while letting them work in unsafe places. 🚀

How do sensors save humans from danger?

Sensors help people by finding danger early and giving warnings. This helps them stay safe. Gas sensors find harmful gases in mines and factories to stop poisoning.

• Temperature sensors check heat in fires and machines to prevent burning.
• Radiation sensors warn workers in nuclear plants about radiation.
• Motion sensors help security systems by spotting danger.
• Water sensors detect leaks to stop floods.

Sensors protect humans by stopping accidents before they happen. 🚨

Input Devices at Home:

A smart device is an electronic device that can connect to the internet and work on its own or with voice commands. It helps people do things easily and quickly.

Examples:

• Smartphone – Makes calls, takes photos, and runs apps.
• Smart TV – Connects to the internet to watch videos.
• Smartwatch – Tracks time, health, and messages.
• Smart speaker – Listens to voice commands to play music or give information.
• Smart lights – Can be turned on/off using a phone or voice.

Smart devices make life simple and fun! 😊

Sensors and safety:

Sensors are devices that detect and respond to changes in the environment, converting physical phenomena into electrical signals for monitoring and control purposes. In the context of safety, sensors play a crucial role by identifying potential hazards and triggering appropriate responses to prevent accidents or damage.

Temperature sensors are a specific type of sensor designed to measure heat energy, allowing systems to monitor and regulate temperature-dependent processes.😎

Using input devices to control output:

Assalamualaikum👩

Input devices (like buttons, sensors, or keyboards) send signals to a computer. Output devices (like lights, speakers, or screens) react to those signals.

Examples:

1. Press a button (input) → Light turns on (output).
2. Clap near a microphone (input) → Music plays from a speaker (output).
3. A temperature sensor detects heat (input) → A fan starts spinning (output).

This is how computers and machines follow commands to make life easier! 😊

Input devices send signals, and output devices react to them.

Examples in Shopping:

1. Barcode scanner (input) → Price appears on the screen (output).
2. Touchscreen at self-checkout (input) → Receipt prints (output).

Examples in a Plane:

1. Pilot moves the joystick (input) → Plane changes direction (output).
2. Passenger presses a button (input) → Light turns on above the seat (output).

This is how machines follow commands to make things work! 😊✈️
