Sensor types

Rain sensor detects fine raindrops on the windshield, so that the whindshield wipers can be triggerd automatically.

• True

• False

The light sensor uses photodiode for its operation

• True

• False

Electrical machines

• Consist of a stationary component (armature) and a rotating component (rotor).

• Consist of a stationary component (rotor) and a rotating component (armature).

• Consist of a stationary component (stator) and rotating component (the rotor or armature).

This sensor can measure the amount of oxygen and determine the air-to-fuel ratio in the combustion.

• two-step lambda oxygen sensor

• lsf4 planar lambda oxygen sensor

• lsu4 planar wide-band lambda oxygen sensor

This sensor can be compare the residual-oxigen content in the exhaust gas with the oxygen content in the reference atmosphere, and indicate a whether a rich or lean air fuel misture is present in the exhaust gas.
