# Requisitos de alimentación de los sensores de calidad del aire

Verkada [Sensores ambientales](https://docs.verkada.com/docs/sensors-quick-start-guide.pdf) utilizan el estándar industrial 802.3af (Power over Ethernet \[PoE]). El consumo de ancho de banda promedio es inferior a 5 kbps. Verkada [Sensores de calidad del aire](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf) puede consumir energía adicional al realizar operaciones, como actualizaciones de firmware o calibración inicial.

La tabla refleja la potencia máxima consumida por un modelo de sensor específico dentro de la temperatura normal.

{% hint style="info" %}
Recomendamos proporcionar un presupuesto de energía adicional en su conmutador para la suma de todos sus sensores.
