Monitoring and control: แบบฝึกหัด

• a.

  Pressure sensor

• b.

  pH sensor

• c.

  Sound sensor

• d.

  Infrared sensor

• a.

  To scan the vehicle's registration plate using infrared light

• b.

  To detect the presence of a large metal object, such as a car, located above the loop

• c.

  To provide wireless charging to electric vehicles while they wait at the barrier

• d.

  To measure the weight of the vehicle to calculate parking fees

• a.

  It ensures the sensor is accurate across a wider range of temperatures by accounting for non-linearities in the sensor's response.

• b.

  It allows the sensor to measure multiple different variables such as humidity and pH simultaneously.

• c.

  It ensures that the sensor is only active at the specific target temperature of \( 22^{\circ}C \), saving energy.

• d.

  It eliminates the need for an actuator to receive signals from the microprocessor when the temperature fluctuates.

• a.

  Rotary actuator

• b.

  Hydraulic actuator

• c.

  Pneumatic actuator

• d.

  Linear actuator

• a.

  To convert the digital signal back into an analogue signal for the microprocessor

• b.

  To ensure that the readings provided by the sensor are accurate and consistent with a known standard

• c.

  To increase the speed at which the sensor detects changes in the environment

• d.

  To allow the sensor to operate without an external power source
