Austin, Tex. National Instruments has released a new instrument driver that gives users of the NI LabVIEW graphical system design platform the ability to interface with environmental monitoring sensors that communicate via SDI-12, a serial-based communication protocol optimized for battery-powered intelligent sensors. The SDI-12 protocol makes it possible to communicate with a wide variety of sensors and recorders that are commonly used in environmental data acquisition applications such as climate change tracking, water quality and testing, ecological research, soil monitoring, agriculture and weather analysis.
With the NI LabVIEW SDI-12 Application Programming Interface (API) software, users can now acquire measurements such as turbidity, dissolved oxygen, tank level, soil pH, conductivity and other critical environmental sensor measurements, making LabVIEW a flexible environmental data-logging solution.
The LabVIEW SDI-12 API, combined with an RS232 to SDI-12 converter and any computer or NI programmable automation controller that includes a serial port, can be used to make environmental measurements in a laboratory setting or deploy standalone systems into remote locations.
Pricing and availability: The LabVIEW SDI-12 API can be downloaded for free from the NI Instrument Driver Network at www.ni.com/idnet
