The regulated d.c. power supply provides a constant standing voltage. The gas diffuses through a porous filter and contacts the surface of the sensor element. A change in resistance occurs that is proportional to the concentration at gas applied. This signal is then amplified and sent to the microprocessor. The microprocessor digitizes the data and processes the information to the L.E.D display and provides any one if a number of outputs to a host controller or monitor.
