Sensor NameDefinitionCurrent Use ExamplesPicture

Light A light sensor measures how much light is shining on it

-Cell phones, TVs, computers etc, for sensing light and darkening or brightening a screen-Robots detecting how much light is coming off an object- Security alarms-senses the disruption of light and alarm sounds

Peizo vibrationA piezo vibration sensor can detect the vibration or -Car vibrations-Vibration in household appliances-Body movement-Security systems

AccelerometerAn accelerometer measures acceleration and movement*Think of how your phone knows that it is facing up or you are moving-Cell phone orientation-Airplane navigation-Measuring vibrations in equipment and cars-Human/animal movement-Collisions/crashes

TemperatureA temperature sensor measures either or both ambient -Sensing temperature of household appliances- Sensing body temperature when wearing a sensor

Humidity (hygrometer)A humidity sensors detects the relative humidity in the surrounding environment*Relative humidity= how much moisture can be held in the air- Indoor measurements for health monitoring -Air quality-Greenhouses-Museums/art galleries

TouchA touch sensor responds -Buttons-Touch screen devices

Gas or chemicalA gas or chemical sensor detects gas/chemical concentration in the air-CO2 monitor-Methane detector for farms

GyroscopeA gyroscope senses rotational motion*Image twirling in a circle while spinning your arms up and downa gyroscope would read all of those motions-Sensing rotation for playing video games on a Nitendo DS or cell phones-Robot balance-Steadying a digital camera to prevent vibration while taking a picture

Hydration Hydration sensors measures the level of hydration in relation to the skin-Measuring the hydration levels of athletes
