Measurement Methods
WMT700 measures wind speed and direction either continuously or for
the duration of the user-configurable averaging time. You can select the
measurement mode over the serial interface.
Continuous Measurement
You can set WMT700 to measure wind data continuously until the sensor
receives the STOP command.
The following data communication methods are available:
- Poll Mode: You can fetch the most recent data from WMT700 with
the polling command. You must specify the data message
identification number in the command.
- Automatic Messaging Mode: If the automatic message interval has
been configured, WMT700 sends automatic data messages at selected
intervals. The data message is user-configurable.
For information on response delay and timing, see section Serial
Interface Timing on page 64.
Wind Measurement on Request
You can set WMT700 to measure wind speed and direction for a
specified period of time. The duration of the measurement can range
from 0.25 seconds to 60 minutes, depending on the configured averaging
interval.
You can fetch the required data message from WMT700 in measurement
mode with the polling command. You must specify the data message in
the command.
