<p>A sensor device containing a gas sensor is exposed to a gas. The gas sensor emits a voltage based on a property of the gas. The voltage output by the gas sensor is received by an integrated circuit (IC). The IC may convert the voltage to a digital representation of the voltage. The IC may determine a property of the gas based on the voltage. The digital representation of the voltage or a representation of the property of the gas is then transmitted as data via an audio jack of the sensor device. A computer device receives the data via an audio jack. Using one or more processors, the computer device analyzes the data and generates a recommendation. The recommendation and the property of the gas may be displayed.</p> |
