A sensor is an electronic component that translates physical states of the world into electronic signals that can then be read by a computer. They are INPUTS to a computer so it can know about the world. Like the keys on your keyboard, the optical tracking of your mouse. A light switch. A volume knob. | A sensor is an electronic component that translates physical states of the world into electronic signals that can then be read by a computer.

More Sensors
Sensor KITs
There are many sensor kits you can buy where the raw component sensors are often mounted on breakout boards for easier, more robust access to their leads (legs) but also sometimes with extra components (resistors, capacitors, leds) on them to make the raw sensor components even easier to use.
