Smoke detector

A smoke detector is a special tool that helps to keep us safe from fires in our homes. It can sense when there is smoke floating in the air and when it does, it makes a loud noise to alert us. This is important because it helps us know that there might be a fire in our house and we can get out safely.

Smoke detectors have a small device inside them that can detect the smoke in the air. When it does, it sends a signal to the alarm, which triggers the loud noise. Sometimes, smoke detectors have a light that flashes along with the noise, which also helps catch our attention.

It's important to have smoke detectors installed in our home's different spaces where fires can occur, like the kitchen or bedrooms. This way, we can know when there is danger and quickly get out of harm's way.

Remember to always check your smoke detectors regularly to make sure they work properly, and change the batteries often to keep them running. Safety first, always!
