Toxic Gas Sensors:

The toxic sensor works by reacting to the concentration diffused through a permeable membrane and reacting to chemicals to produce a linear output proportional to the con-centration. In addition, the toxic sensor incorporates a third reference electrode.

The reference electrode maintains the potential so the output remains fixed in respect to the sensing electrode. This maintains a stable baseline with no effects to atmospheric pressure.

Oxygen Sensors:

The oxygen sensor works by reacting to the concentration of oxygen diffused through a permeable membrane and reacting to chemicals to produce a linear output proportional to the concentration.
