SOLID STATE GAS DETECTION SENSOR DIAGNOSTIC |
| 摘要 |
A metal oxide semiconductor-based toxic gas detector is provided. The metal oxide semiconductor-based detector includes a metal oxide semiconductor-based gas sensor that has an electrical characteristic that varies with concentration of a toxic gas. Measurement circuitry is coupled to the metal oxide semiconductor-based gas sensor and is configured to measure the electrical characteristic and provide a digital indication of the measured electrical characteristic. A controller is coupled to the measurement circuitry and is configured to provide a toxic gas output based on the digital indication. The controller is also configured to provide a diagnostic output relative to the metal oxide semiconductor-based sensor based on fluctuations of the measured electrical characteristic over time. |

1. A metal oxide semiconductor-based toxic gas detector comprising:
a metal oxide semiconductor-based gas sensor, the gas sensor having an electrical characteristic that varies with concentration of a toxic gas; measurement circuitry coupled to the metal oxide semiconductor-based gas sensor, the measurement circuitry being configured to measure the electrical characteristic and provide a digital indication of the measured electrical characteristic; and a controller coupled to the measurement circuitry and configured to provide a toxic gas output based on the digital indication, the controller being further configured to provide a diagnostic output relative to the metal oxide semiconductor-based sensor based on fluctuations of the measured electrical characteristic over time. |
