The SNiP-DBS4 is a 'Sensor Node Integrated Package' for LoRaWAN or CAT-M1 communication of real-time plant diameter measurements for continuous plant monitoring.
The base SNiP-DBS4 integrates 1x S-NODE and 1x DBS60 Band Dendrometer With Modified Fixing Plate to a site’s unique network, communication and power requirements. The S-NODE can support an added 3x DBS60 Band Dendrometer devices.
The DBS60 Band Dendrometer is an SDI-12 Band Dendrometer designed to measure short- and long-term changes in stem circumference, with the modified fixing plate allowing the package to monitor trunks with a minimum diameter of 40mm.
Further parameters can be added to the SNiP, without requiring loggers to match each distinct sensor, substantially reducing the cost of getting a fuller picture on the application. The S-NODE can support 3x additional SDI-12 sensors to the base package; see other IoT Nodes to include further sensor extensions in a custom Sensor-Node IoT Package.
The S-NODE (for Environmental Monitoring) has been designed to support the broad suite of SDI-12 based environmental sensors. The S-NODE can support sensors with higher power requirements; a solar panel can charge either the internal lithium-ion battery or both the node and sensor can be powered by an external 12V system (e.g. battery or mains source).
A decoder suitable for TTN will be provided based upon sensor configuration.
The DBS60 is an SDI-12 Band Dendrometer designed to measure short- and long-term changes in stem circumference.
The DBS60 SDI-12 Band Dendrometer is similar to the DBL60, but has a cable for the connection to a SDI-12 Data Logger.
