What is the difference between contact sensors and contactless sensors

• Contact sensors need direct contact with objects while contactless sensors don't need

• Contactless sensors need direct contact with objects

• Contact sensors don't need direct contact with objects

• there is no difference

Which of the following function block of a mechatronic system is responsible for performing physical actions and execute the commands provided by the controller

• Actuator

• Controller

• comparator

• Sensor

Which of the following correctly describes the relationship between a sensor and a controller in a mechatronic control system?

• Controller monitor variables and sensor take control decisions

• There is no relation at all

• Controller monitor variables and sensor take control decisions

• Sensors monitor the physical variable like temperature, controller processes the sensor data

How does capacitive sensor operate

• By measuring the changes in capacitance resulting from the proximity of objects.

• By emitting sound waves and measuring their reflection.
  
  

• By detecting changes in resistance due to temperature variations.

• By analyzing the variations in magnetic fields around conductive materials.
  

How does a solenoid work?
