Wireless USB Gateway

The WSDA®-200-USB is a USB gateway for easy, reliable data acquisition from Lord wireless sensors. The gateway provides seamless communication between the wireless sensor nodes and host computer using SensorConnect software or the MSCL API. The software and gateway allows users to easily configure wireless nodes and deploy them into a synchronized and scalable network.

Lord wireless sensor networks are fast to deploy and provide reliable, lossless data throughput. These networks are proven to work in demanding industries where reliable data acquisition is critical.


LORD Sensing Wireless Sensor Networks enable simultaneous, high-speed sensing and data aggregation from scalable sensor networks. Our wireless sensing systems are ideal for test and measurement, remote monitoring, system performance analysis, and embedded applications.

Gateways coordinate and maintain wireless transmissions across a network of distributed wireless sensor nodes. The LORD Sensing LXRS and LXRS+ wireless communication protocols between compatible nodes and gateways enable high-speed, synchronized sampling and lossless data throughput at rates up to 16 ksps.

Users can easily program nodes for continuous, periodic burst, or event-triggered sampling with the SensorConnect software. The optional web-based SensorCloud interface optimizes data aggregation, analysis, presentation, and alerts for sensor data from remote networks.
