Rate monitor Rate sensors are devices that directly measure angular rate, without integration in conditioning electronics. Gyroscopes also measure angular rate. Generally gyroscopes are able to measure a constant rotation rate, while rate sensors also include devices with a low cut off frequency that is other than zero.

Accelerometer An accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity, or speed divided by time

magnetometer Magnetometers are measurement instruments used for two general purposes: to measure the magnetization of a magnetic material like a ferromagnet, or to measure the strength and, in some cases, the direction of the magnetic field at a point in space.

light sensor A Light Sensor is something that a robot can use to detect the current ambient light level - i.e. how bright/dark it is. There are a range of different types of light sensors, including 'Photoresistors', 'Photodiodes', and 'Phototransistors'.

gyroscope Uses of a gyroscope or accelerometer. The main difference between the two devices is simple: one can sense rotation, whereas the other cannot. In a way, the accelerometer can gauge the orientation of a stationary item with relation to Earth's surface.

barometer, proximity sensor A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal.

Temperature These sensors use a solid-state technique to determine the temperature. That is to say, they don't use mercury (like old thermometers), bimetallic strips (like in some home thermometers or stoves), nor do they use thermistors (temperature sensitive resistors).

camera Early analog sensors for visible light were video camera tubes; currently used types are semiconductor charge-coupled devices (CCD) or active pixel sensors in complementary metal–oxide–semiconductor (CMOS) or N-type metal-oxide-semiconductor (NMOS, Live MOS) technologies.

touch screen A touch screen sensor is a clear glass panel with a touch responsive surface. The touch sensor/panel is placed over a display screenso that the responsive area of the panel covers the viewable area of the videoscreen

Basic pedometers consist of a mechanical sensor that counts steps by taking into consideration how much the body shakes. An internal ball or similar object moves up and down with the motion of the person wearing the pedometer, effectively sensing the vibrations of his or her feet hitting the pavement through hip movement. As the ball moves, it activates a switch that in turn clicks the counter forward. Simply shaking the pedometer gives the same result, even without walking, which shows how the device works. pedometer, heart
