The Sequoia LISST-ABS Acoustic Sediment Sensor is designed specifically for measuring suspended sediment concentrations at a single point. The LISST-ABS is compatible with NexSens X-Series data loggers using the SDI-12 communication protocol and sensor interface. A pre-defined script on X-Series data loggers is able to detect, log, and transmit all parameters from the sensor. Parameter […]

X2 Environmental Data Logger Overview
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 WQData LIVE web data center via Wi-Fi, cellular, radio, or satellite telemetry. There, data is presented on a fully-featured and easy-to-use dashboard where remote, […]

Instrument Installation in CB-25 Data Buoy
The CB-25 Data Buoy have a solar tower plate allowing the installation of top-side mounts for GPS units and weather stations. Three 1.5″ sensor pass-through ports and the optional purchase of an EXO cage for the EXO series of YSI EXO sondes allow for multiple platforms for deploying subsurface water quality sensors. Cage Installation […]
CB-25 Data Buoy Overview
The CB-25 Data Buoy is a simple, compact platform that integrates the X2-SDLMC Submersible Data Logger for both water and atmospheric observations. The buoy features (3) 1.5″ sensor pass-through ports, an integrated solar tower with (3) 4-watt solar panels, and a topside plate supporting a solar marine light, weather stations, and other environmental sensors. An […]
Access the Data Export Tool
The Data Export feature is a quick and simple data acquisition tool that allows users to download or send data through email or FTP in CSV or multiple XML formats without loading data directly onto the WQData LIVE page. This feature removes the latency associated with loading a substantial data set. To access the […]
Set Log and Transmit Start Times
The log start time and selective upload interval(s) can be set through the Advanced Device Remote Configuration tool. These features allow the X2 to log data to its internal memory at a specific log start time and control the transmission of certain parameters. These features help reduce system data usage and telemetry on-time. Adjust […]
Update Data Logger Settings
For proper transmission, the internal data logger settings must match the settings on WQData LIVE. Multiple commands will achieve this purpose depending on the telemetry model of the logger. Both commands can be accessed from the Advanced Device Remove Configuration Tool within the administrator settings. The Sync settings command applies to Wifi and cellular telemetry […]
Accessing the Advanced Device Remote Configuration Tool
The Advanced Device Remote Configuration tool allows the user to adjust the following: Update data logger settings Set the log and transmit start times Change which parameters are logged and transmitted Change the data logger transmission settings To access the tool: Navigate to the ADMIN | Settings tab found at the top of the project Dashboard. […]
Averaging Logged Sensor Data
Averaging for sensor parameters may be enabled by adjusting the log and sample intervals in the Device Remote Configuration Tool within the administrator settings. Log Interval: Frequency of data written to the data logger memory to be transmitted to the web. Sample Interval: Frequency of data read from the sensor by the data logger internally. […]
