Overview
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, ADCPs, 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
Power options include SP-Series Solar Power Packs, an AC adapter, or an external 12 VDC. Advanced power management combined with ultra-low sleep and run currents extends battery life and eliminates 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.
Remote Data Access
Standard Wi-Fi and 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.
Easy Setup
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.
