Working Principle of the H2S-A1 Sensor
The H2S-A1 sensor operates on the Metal Oxide Semiconductor (MOS) principle. A thin layer of metal oxide is deposited on a ceramic substrate within the sensor. When H2S gas interacts with the sensor’s surface, it induces changes in the electrical resistance of the metal oxide layer. These variations in resistance are then measured by the sensor’s electronic circuitry, generating an output signal indicative of H2S gas presence.
Important Considerations
- Prior to deploying the H2S-A1 sensor, thorough examination of its datasheet is imperative.
- Installation should be conducted in a clean, dry environment to ensure optimal performance.
- Avoid exposure to direct sunlight, high humidity, and corrosive chemicals to prolong sensor lifespan.
- Regular calibration sessions are necessary to uphold the sensor’s accuracy and reliability.
