signal line for air quality sensor

Air Quality Sensor (Rev. A) - Texas Instruments

Consumer air purifiers can also benefit from incorporating air quality sensors into their designs. Instead of an unintelligent and rudimentary air purification algorithm, enhancements can be added to purify air only if the AQI crosses a preset or programmable threshold. This level of intelligence would reduce the overall power consumption of the design by minimizing the duty cycle of the ...
