# Air Quality Sensor Status LED

Each Verkada [Air Quality Sensor](https://www.verkada.com/air-quality/sensors#overview) is equipped with an outside LED light. This light indicates its operating status. Verkada offers the [SV11](https://www.verkada.com/sensors/sv11/) series and SV20 series (including [SV21](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf), [SV23](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf), [SV25](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf)).

## SV20 series

The newer SV20 series ([SV21](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf), [SV23](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf), [SV25](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf)) uses a white LED indicator; however, its status is analogous to that of the blue LED on the SV11.
