Sensors
There are 5 basic sensors. They are vision, hearing, smelling, tasting and feeling sensors. The vision sensor senses light and dark. It completes an action when a certain brightness or darkness. Some vision sensors can detect motion. The hearing sensor can capture sound waves via molecular vibrations in the air. For example it can capture the vibrations generated from your clap. But, it ca﻿n also hear ultrasonic waves use to detect hidden objects. The pressure/temperature sensor can feel any pressures and temperature changes, and can react upon it. The smell sensor﻿ can detect smell like your nose, it's used for gas alarms in kitchens. The taste sensor senses taste by electronic circuit. But, it cannot differentiate bad tastes from good tastes since it is a very complicated sensor. There are other sensors like the IR sensors used for TVs. Sensors are all around even if we don't know it.
