The SapIP wireless data logging system from Dynamax, Inc., with EXO or Dynagage sap flow sensors, can be used to measure plant water use in “real-time” with no calibration. The SapIP gateway can monitor up to (25) SapIP nodes with (2) sap flow sensors each. The nodes can be located up to 5,000 feet away from the gateway module. Data is collected and analyzed through the Dynamax website for easy monitoring and data download.
The Sap-IP sap flow system solves many field data collection issues with a state-of-the-art wireless data collection platform. This new system was developed so field monitoring would not require wiring sensors to a central data logger and data could be collected remotely. Cables can be expensive, hard to maintain, and difficult to move around in the field, and existing RF data loggers and low cost motes typically do not have the range, power management, accuracy or resolution required for scientific grade sensors. The Sap-IP system solves all these problems and is a breakthrough for most field monitoring applications.
Remote data collection from widely distributed sensor networks has many environmental, commercial, and agronomic applications, and this highly efficient and low power RF solution is integrated into a single module, making an excellent, low cost, easy to install solution for field research. The system can be used with EXO sensors, Dynagage sensors, TDP sap velocity probes, or soil moisture sensors. Plans for compatibility and use with a variety of environmental sensors is in process.
