Description

El sensor W3910 con salida de red LoRaWAN mide la temperatura y la humedad mediante su sensor interno integrado y puede instalarse directamente en el entorno de medición gracias a su carcasa con clasificación IP65. Los dispositivos LoRa se alimentan mediante una batería reemplazable con una vida útil de hasta 10 años (3 años estándar). También está disponible la alimentación externa con accesorios opcionales. El sensor puede utilizarse con una tapa adecuada incluso en las condiciones más exigentes.

Los valores medidos se transmiten de forma inalámbrica a intervalos ajustables (de 5 minutos a 24 horas) al almacenamiento en la nube de COMET, donde los usuarios pueden acceder a ellos a través de un ordenador o dispositivo móvil. Los sensores se configuran remotamente desde la nube de COMET y tienen la capacidad de monitorizar hasta dos umbrales de alarma; cualquier exceso se notifica mediante una alerta enviada al usuario. Características principales

Transmisión inalámbrica de valores medidos y estados de alarma
Alimentación por batería con indicador de batería baja (duración de la batería de hasta 10 años) y opción de alimentación externa
Configuración remota del dispositivo a través de COMET Cloud
