Sensors are found in everything from simple touch-sensitive elevator buttons and table lamps to sophisticated industrial applications found in fluid processing, aerospace and automotive industries.
With advances in micro-machinery and easy-to-use micro-controller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure or flow measurement, into MARG (Magnetic, Angular Rate, and Gravity) sensors and consist of either solid-state or micro-electromechanical systems (MEMS) such as gyroscopes, accelerometers and magnetometers which are replacements for traditional mechanical gyroscopic flight instruments.
