Winsen Electronics, research and produce air quality monitoring gas sensor for home and office air cleaners, and fresh air system. The higher the concentration is, the higher conductivity of the sensor gets. Users can adopt a simple circuit to convert the variation of conductivity into an output signal corresponding to the gas concentration.
Applications
It is used in automatic exhaust devices, and air cleaners on domestic occasions for harmful gas detection.
Features
High sensitivity to toluene, benzene, formaldehyde, and other organic gases
Small component size
5V constant voltage, low power consumption
Fast response and recovery characteristics
Simple drive circuit
Excellent stability and long service life
