Node Programming (LabVIEW WSN)

The LabVIEW Serial Compatibility API helps you configure baud rate, stop bits, parity bits, and flow control. Using the API, you can initialize the serial channel, send commands to

the serial device, and then read back and parse the returned data, all locally without over-the-air communication and associated latency. Then you can send important data over

the air back to the WSN gateway/host machine via UDVs. Figure 7 shows an example. "Temperature," "Status," and "String from Sensor" are three different types of user-defined

variables that contain information from the serial device.

Figure 7. Use LabVIEW WSN to create a programmable serial interface to sensors, instruments, and control boards.

In addition to using the LabVIEW WSN Module to create a local, autonomous interface to serial devices, you can use this module to perform custom analysis, extend battery life,
