The lambda probe or oxygen sensor is a sensor which provides information about the oxygen content
in the exhaust fumes. The signal generated is not of the proportional but of the ON/OFF type, i.e. whether
there is oxygen or not. The probe is positioned on the exhaust manifold before the catalytic converter
in an area where the gas temperature is always high. The temperature at which the probe works is at
least 350°C at 600°C and it has a reaction time of just 50 milliseconds. The signal generated passes
from a high value to a low one with a mixture with lambda =1.
