The document reports the results of the study conducted by the Carnegie Mellon Research Institute (CMRI) to evaluate its recently developed metal oxide semiconductor (MOS) gas sensor technology for applications in the automobile environment. The specific use of the technology is for a low-cost carbon monoxide (CO) monitor to be placed in the automobile compartment to protect the driver and passengers. The approach followed in the study was first, to define the physical and chemical characteristics of the vehicle's compartment and the surrounding environment; second, to evaluate the effects of these environments on the MOS sensor performance in terms of sensitivity, selectivity and stability. The comparison of the chemical environment with MOS sensor data previously collected by CMRI, revealed the feasibility of the technology for CO monitoring in cars and other highway vehicles. Preliminary designs of the sensor chip, filter and electronics are presented in the document.
