NexSens X3 Environmental Data Logger

The X3 is an all-in-one environmental data logger designed for both pole/wall mount and buoy-based applications. The three waterproof sensor ports are compatible with most environmental sensors including multi-parameter sondes, water quality sensors, temperature strings, ADCP’s, water level sensors, and weather stations. All connections are made with a simple thread-in connector, and the built-in sensor library automatically facilitates setup and configuration. Data is stored on common or independent schedules.

Power options include SP-Series Solar Power Packs, AC adapter, or external 12 VDC. Advanced power management combined with ultra-low sleep and run currents extend battery life and eliminate the need for multi-battery arrays or large solar charging systems. The X3 monitors itself while collecting environmental data - internal temperature, humidity, voltages and currents are constantly recorded, and failure alerts can be sent automatically to a predefined list of contacts.

Using Bluetooth or a USB adapter and CONNECT Software, users can configure the X3 Data Logger for deployment, view live data, change settings, or troubleshoot. Optional integrated 4G LTE cellular or Iridium satellite telemetry modules offer 2-way remote communications via the WQData LIVE Web Datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, email/text alarms, public portal, API, and much more.
