NexSens X2 Environmental Data Loggers

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.

Questions & Answers
Do analog sensors work with this logger?
Yes, analog sensors can be fit to a mV-adapter for use with this logger.
Is the logger water proof?
Yes, although it is not rated for submersion.
What sensors are compatible with the X2 data logger?
The X2 data logger is directly compatible with sensors that have a native SDI-12, RS-485 or RS-232 output. The data logger can also support analog sensors using an analog-to-digital adapter (PN# mV-RS485) or tipping bucket rain gauges using a pulse-to-digital adapter (PN# RAIN-RS485). There are three tiers of sensor compatibility with the X2 data logger: Tier 1 Sensors have auto-detect, which connects sensors automatically without programing -- no prior setup required. Tier 2 Sensors must be configured with manufacturer-specific software before connecting to logger. Prior to data logger connection, customers can specify preferred types of parameter outputs. Tier 3 Sensors can be added through the creation of a user-defined script. The script is written in Lua and utilizes NexSens-created functions to simplify programming. As long as the sensor communicates using SDI-12, RS-485, or RS-232 and can be powered from a 12V supply, it should be compatible with the X2 data logger. See the complete list of supported sensors and associated tiers HERE.

Susquehanna River Basin Commission: Cloud Data and Water Quality Monitoring

As technology becomes more closely interwoven with water quality monitoring, some organizations have found themselves forced to catch up, but not the Susquehanna River Basin Commission (SRBC) . The SRBC has had a long-standing relationship with remote data collection. With the establishment of their Early Warning System (EWS) in 2003 and their Remote Water Quality Monitoring Network (RWQMN) in 2010, the commission has shown clear dedication to water quality monitoring. Background and History of the Continuous Instream Monitoring System The EWS and RWQMN merged to become the Continuous Instream Monitoring system . Environmental scientist Dawn Hintz shares, “The original intent of the RWQMN was completely related to natural gas, to the unconventional natural gas industry.

Wireless Mesh Environmental Sensing Network System Tested

For scientists working in the field, monitoring for data isn't enough—you have to get that data back. This is of course true, no matter how sophisticated a real-time monitoring solution is. Recent testing of a wireless mesh environmental sensing network at Virginia Tech reveals a promising new option for this kind of problem, and Innovative Wireless Technolog ies (IWT) principal investigator Matthew Fisher spoke to EM about the testing and the network: Envōk . Solving data transmission difficulties wirelessly Since 1997, Innovative Wireless Technologies has been developing wireless products that use 900 megahertz radios in mesh networking technologies.
