Vaisala WXT-Series Weather Sensor X-Series Integration Guide


Vaisala WXT-Series Weather Sensors provide up to six of the most important weather parameters, including air pressure, temperature, humidity, rainfall, wind speed, and direction. The weather sensors are compatible with NexSens X-Series data loggers using the SDI-12 sensor interface and communication protocol.

Sensor Setup

First, follow the manufacturer’s guidelines to complete sensor setup. Be sure to set the station to Continuous Measurements Mode and adjust the SDI-12 address as needed if connecting other SDI-12 sensors.

 

Connecting with X-Series Loggers

Next, the Vaisala WXT-Series weather sensor will need to be set up for the X-Series logger using the CONNECT software.

  1. Connect the sensor using the supplied cable to one of the open sensor ports on the logger and note the port number.
  2. Enable the pre-loaded sensor profile.
    1. Configure Sensor Scripts
    2. Note: The Vaisala weather station is #2002 in the list
  3. Complete the setup for all other sensors, and then run sensor detection in CONNECT.
    1. Run a Sensor Detection
  4. After ~5-10 minutes, read the sensor configuration to confirm detection. Let the unit gather a few readings to confirm that readings are accurate and reasonable.

Mounting

Deployment setups will vary based on the platform, application, and site location. For general buoy mounting instructions and shore-side mounting options, see below.

 

Buoy-Based Deployments

First, follow the appropriate User Guide in the Knowledge Base for buoy assembly. Then, use the NexSens Vaisala WXT-Series Weather Sensor Buoy Mount to attach the sensor to the buoy cage by following the steps below.

  1. Remove the included hardware from the threaded end.Remove the included hardware from the threaded end.
