Aranea : Network gateway for SARAD instruments

The components of the Aranea family enable the remote control of SARAD measuring devices with the help of the SARAD application software Radon Vision 8, dVision 4 or ROOMS as well as the handover of measuring data to monitoring software of third party providers.

Depending on the device and service option, different tasks can be performed:

Aranea LAN

Remote control within an Ethernet-based local area network (LAN)

Aranea LAN with SARAD MQTT Broker

Remote control of measuring devices in a LAN via the internet

Aranea LTE

Remote control via mobile communications and the internet

Aranea Outdoor

Remote control via mobile communications and the internet, with weatherproof LTE modem

On the hardware side, Aranea LAN is a Raspberry Pi mini computer with an uninterruptible power supply. With Aranea LTE or Aranea Outdoor this computer is extended by a LTE USB modem for use inside or outside buildings, respectively, so that remote control and telemetry are possible via mobile communications and the internet regardless of the presence of LAN infrastructure.

The Aranea basic unit has a wide-range input for voltages between 6 and 61 Volt. This is the standard input to be used with the supplied plug-in power supply. The integrated real-time clock is programmable so that you can create schedules to switch on your Aranea system only at certain times and thus to save energy on battery-operated systems.

On the software side, all Aranea devices are almost identical. The Raspberry Pi runs a Linux operating system configured appropriately for the intended use (Raspberry Pi OS) and the SARAD Registration Server Service. The latter is preconfigured at the factory but can be configured in a variety of ways depending on the intended use.
