Product Specs
The Layer N SP-003 / SP-004 Environmental Monitoring Smart Probe provides temperature, relative humidity, and barometric pressure readings. The SP-003/ SP-004 accepts Layer N Smart Interfaces through its M12 8-pin connector.
Intuitive Configuration
Configure your Layer N Smart Probe using SYNC’s intuitive configuration interface. Additionally, an integrated command line interface allows for quick serial setup of your Smart Probe and Smart Interface using standard terminal emulators.
Smart Core Enabled
Smart Core is integral to all Layer N Smart Probes. This powerful suite of advanced features enable plug and play connectivity, alarms and notifications, data assurance, data logging, and storage.
Smart Interface Modularity
Customize your Layer N Ecosystem with modular Smart Interfaces that connect and transmit data from your Smart Probe to the Layer N Cloud.
Edge Control and Built in I/O
The Layer N SP-003/SP-004 features 2 configurable digital I/O pins. These can be used for a myriad of applications including driving relays, physical alarms, or sensing dry contacts like door switches. The SP-003/SP-004 can also be utilized as an edge controller, with autonomous independent decision-making capabilities to generate local alarms or provide control outputs based on sensor inputs.
Your Data at a Glance with Layer N Cloud
Layer N Cloud consolidates and brings your data to you when you need it, wherever you are. The intuitive cloud interface allows you to monitor and store your data, set alarms and alerts, and provides insights on device activity. Visit the OMEGA website for more details.
