Field devices sense conditions, execute commands and feed intelligence to building management systems.

The Sensing and Actuation Layer for Building Automation

Field devices form the data foundation and control execution points in building automation. Sensors measure environmental conditions. Actuators and valves respond to control signals. Energy meters track consumption. Together they enable improved comfort, efficiency, safety and operational intelligence.

Frequently Asked Questions About Field Devices and Monitoring Systems

Honeywell provides sensors for temperature, humidity, pressure, occupancy, CO2, PM2.5 and TVOC. Our portfolio also includes actuators, valves, variable frequency drives, thermostats, wall monitors, economizers, energy meters and commercial thermostats.

Field devices communicate through a variety of open protocols including BACnet, Modbus, LonWorks and Sylk bus. This enables integration with Honeywell controllers and third-party BMS platforms through standard data points and control signals.

Portfolio breadth—from sensing to actuation to metering—enables a more complete automation approach from one vendor.

 

  • High integration provides rich data for analytics.  
  • Long-term stability can help reduce recalibration. 
  • Multi-protocol support offers system flexibility.

Field devices stream data to platforms like Honeywell Forge Performance+ for Buildings, which uses analytics and equipment models to help identify anomalies ahead of potential failures. Sensors feed temperature, pressure and other parameters through BMS integration or wireless connectivity. The platform establishes performance baselines, identifies deviations and generates configurable automated alerts, supporting proactive maintenance instead of relying solely on reactive repairs.
