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.

CO2 sensor: This sensor measures CO2 concentration using infrared light.

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.
