WSDA - Wireless Sensor Data Aggregator

2.4 GHz wireless sensor networks

MicroStrain's wireless sensor networks enable simultaneous, high-speed sensing and data acquisition from multiple wireless strain gauges, accelerometers, temperature, and millivolt inputs. The range of wireless sensing systems is ideal for both small scale applications requiring a few sensor nodes and large scale applications requiring hundreds of sensor nodes. OEM options are available for embedded applications.

Ruggedized, single-board computer with Ethernet and optional cellular connectivity designed to collect data from networks of wireless sensors. SensorCloud™ enabled.

The Wireless Sensor Data Aggregator (WSDA® -1000) is a single-board computer with ethernet connectivity designed to collect data from networks of distributed wireless sensors. The WSDA® -1000 is capable of collecting data from a wide range of MicroStrain® wireless sensor nodes operating in LDC or Synchronized sampling mode. The wireless sensor network can be set up and controlled remotely via MicroStrain® NodeCommander® software. Once set up, the WSDA® -1000 may operate in one of three distinct modes: SensorCloud™ Enabled, LAN (Local Area Network), and Standalone.

WSN Setup

The wireless sensor network can be setup, modified, and monitored using the WSDA® -1000 in conjunction with MicroStrain® NodeCommander® software. This capability enables the user to remotely control the Wireless Sensor Network from any PC provided sufficient network access is available.

SensorCloud™ Enabled

Optionally, the WSDA® -1000 seamlessly integrates with SensorCloud™, a unique data visualization application, which allows the user to navigate through gigabytes of data within seconds and quickly drill down to points of interest. If enabled, sensor data is autonomously and securely pushed up to SensorCloud™ periodically. Data is locally cached in case of Internet connectivity disruption thereby safeguarding data integrity. The WSDA® -1000 comes with a free basic account on SensorCloud®, and the upload option is available within the WSDA® -1000 web interface.

Local Data Acquisition on a LAN

If SensorCloud™ upload is disabled, the WSDA® -1000 may act as an autonomous data logger on a LAN with a DHCP server. In this mode, the WSDA® -1000 only stores data on locally on the 2 GB embedded flash. Data can be downloaded and cleared from the WSDA® -1000 using the download tool.

Standalone Mode

If a LAN with a DHCP server is unavailable, the WSDA® -1000 may also operate autonomously as a wireless sensor network data logger. In this mode, the WSDA® -1000 stores data locally on the 2 GB embedded flash. Using the WSDA® downloader tool with a crossover Ethernet cable, the user can download and clear data from the WSDA® -1000. This is useful in applications where network access is unavailable.
