The X2 is an all-in-one environmental data logger that can be controlled from any internet browser using a smartphone, tablet, or PC. It automatically recognizes sensors and sends data to the web via cellular or Iridium satellite telemetry. The X2 includes three sensor ports that are compatible with most environmental sensor protocols including SDI-12, RS-232, and RS-485. 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 packs, AC adapter, or external 5-16 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. Smart power circuits automatically switch to reserve power when the main source is depleted. The X2 monitors itself while collecting environmental data. Internal temperature, humidity, voltages and currents are constantly recorded. Failure alerts can be sent automatically to a predefined list of contacts.
Using a USB adapter and CONNECT Software, users can configure the X2 data logger for deployment, view live data, change settings, or troubleshoot. Optional integrated cellular or Iridium satellite telemetry modules offer real-time 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, alarms, push notifications and much more.
