SensorsSensor Guide Select by Method/Principle

Murata pursued sensing functions making full use of MEMS and processing technology, and magnetoresistive elements including ceramic material technology in order to develop highly efficient and highly reliable devices, modules and systems. A lineup of various sensors respond to the sensing needs of various applications for automobile, wearable, medical care and health care.

Sensors

Temperature

Thermistors:The resistance changes with the temperature.

Infrared

Pyroelectric infrared sensors:The sensor reacts to the infrared radiation emitted from the human body to output an electric charge.

Distance

Ultrasonic sensors:The sensor sends and receives ultrasonic waves in order to detect distances from the state of the reflected wave.

Open/Close

Magnetic switches:This switch switches built-in ICs when the magnetoresistive element detects the magnetic proximity.

Inertial force

  • Accelerometers:This sensor detects the acceleration from the change of the capacitance which occurs in the 3DMEMS element.
  • Inclinometers:This sensor detects the gravitational acceleration of the Earth to calculate the angle of gradient.
  • Gyro Sensors:This sensor detects the angular velocity from the change in the capacitance which occurs in the 3DMEMS element.
  • Shock sensors:This sensor generates an electric charge according to the acceleration (stress) applied to the piezoelectric element.

Magnetic

Magnetic switches:This switch switches built-in ICs when the magnetoresistive element detects magnetism.
