Sensors

 In the broadest definition, a sensing element may be a device, module, machine, or system whose purpose is to sight events or changes in its surroundings and send the knowledge to different physics, oftentimes a pc processor. A sensing element is often used with different physics.     Sensors area unit utilized in everyday objects like touch-sensitive elevator buttons (tactile sensor) and lamps that dim or brighten by touching the bottom, besides incalculable applications of that most of the people area unit ne'er aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have enlarged on the far side the normal fields of temperature, pressure or flow measuring, for instance into MARG sensors. Moreover, analog sensors like potentiometers and force-sensing resistors area unit still wide used. Applications embody producing and machinery, airplanes and region, cars, medicine, artificial intelligence and lots of different aspects of our every day life. There area unit a good vary of different sensors, measurement chemical & physical properties of materials. a number of examples embody optical sensors for index of refraction measuring, undulation sensing elements for fluid consistency measuring and electro-chemical sensor for observation pH scale of fluids.
