BluSENSE Hardware
BluNODE
Modular Monitoring Hardware for Every Zone, System, and Sensor Type. BluNODE is BluSENSE's modular data logger — purpose-built to connect sensors to your monitoring network with precision and flexibility. Deploy standalone or pair with BluCORE to extend monitoring reach across zones, floors, and building systems.
Built for the Real World
One Device.
Every System.
Building monitoring rarely fits a single template. Different zones demand different sensors. Different applications demand different inputs. BluNODE is designed for that reality — a compact, capable logger that handles temperature, pulse, Modbus, and CT inputs out of the box, with expansion options for 4-20mA analog signals when your application calls for them.
Standalone or networked. Local logging. No subscriptions.
Key Benefits

Real-World Applications
Where BluNODE Excels
From single-zone deployments to multi-floor networks, BluNODE delivers where sensor-level precision matters most.
Track airflow, temperature differentials, and system performance across air handling units, VAV boxes, and duct systems — at the zone level, not just the equipment level.
Monitor supply and return temperatures, flow rates, and pressure across domestic hot water and hydronic systems — with granular data at the point of use.
Connect to pulse meters for water, gas, and electricity submetering at the tenant, floor, or end-use level — extending your monitoring reach without replacing existing meters.
Use CT inputs to monitor current draw across circuits, panels, and equipment — identifying demand peaks, load imbalances, and energy waste at the circuit level.
Deploy multiple BluNODE units across a large building or campus, networked through BluCORE for centralized data aggregation, analysis, and reporting.

The BluSENSE Ecosystem
How BluNODE Works with Your Network
BluNODE operates independently or as a distributed sensing node within a larger BluCORE network — deploy where you need it, scale when you're ready.
Deploy BluNODE as a self-contained data logger for localized monitoring — ideal for single systems or zones where a full BluCORE deployment isn't required.
Pair one or more BluNODE units with a BluCORE hub to extend monitoring reach across your facility. BluCORE handles centralized data processing, communications, and reporting — BluNODE handles the sensing.
Combine BluNODE with BluPULSE nodes to capture pulse meter data from existing utility meters alongside direct sensor inputs — integrating legacy infrastructure without replacing hardware.

BluNODE FAQ
Questions About BluNODE?
Everything you need to know about configurations, sensor compatibility, deployment options, data access, and support — answered. Can't find what you're looking for? Talk to an expert.
-
The base BluNODE supports temperature, pulse, Modbus, and CT inputs — covering the majority of building monitoring applications. BluNODE CL adds a 4-20mA analog input board, enabling connection to industrial sensors such as pressure transducers and analog flow meters that output a 4-20mA signal.
-
Yes. BluNODE can function as a standalone data logger, recording sensor data locally. For centralized communications, automated reporting, and multi-zone data aggregation, pairing with BluCORE is recommended.
-
Multiple BluNODE units can be networked through a single BluCORE hub. The exact number depends on your facility layout and configuration — contact our team for guidance on larger deployments.
-
BluNODE supports a wide range of sensors across temperature (One-Wire), pulse, Modbus RS-485 devices, and current transformers. The CL expansion board adds compatibility with 4-20mA analog sensors including pressure, flow, and level sensors.
-
Yes. BluNODE is designed for both new construction and retrofit applications. Its flexible input options make it straightforward to connect to existing sensors and meters already installed in your facility.
-
Three support plans are available — The Starter, The Partner, and The Advisor — covering everything from initial sensor selection and hardware design through ongoing remote support and senior expert consultation.
