Figure 2-3 is a block diagram of the signal processing electronics described below.

Figure 2-3: Signal Processing Block Diagram

In the presence of oxygen the sensor generates a millivolt potential which is fed to a voltage amplifier. The output from the sensor amplifier is sent to an analog to digital converter (ADC), and the resulting digital concentration signal is passed to the micro-controller. The ADC has a second channel which monitors the temperature of the probe.
