Sensors provide information that a controller can use to change lighting operation. The correct sensor is determined by the condition that needs to be detected, not simply by the presence of an automated lighting system.
Control Inputs
Detecting Conditions Around the Lighting System
Sensor inputs can represent presence, movement, ambient illumination, equipment position, temperature, process state, or other measurable conditions.
The controller then interprets that input according to the operating logic of the machine or facility.
Presence Detection
Lighting Occupied Work Areas
Presence or occupancy sensing can be used where a work area does not require continuous illumination. Sensor placement must provide appropriate coverage without being blocked by machinery, racks, or workstation structures.
Machine Position
Lighting Based on Equipment State
Machine controls can use position or state inputs to determine when task or inspection lighting should operate.
The lighting function should remain separate from safety functions unless the complete machine architecture has been designed accordingly.
Ambient Conditions
Responding to Available Light
Ambient-light sensing can support control schemes that change artificial lighting according to the illumination already present in the space.
Sensor position matters because a sensor located directly beneath a luminaire may measure different conditions from the actual work plane.
Electrical Integration
Connecting Sensors to Controls
Sensors require compatible power, outputs, wiring, connectors, and control interfaces. Their signals may be interpreted by a dedicated lighting controller or by broader machine electronics.
Lighting Control Systems →Physical Installation
Mounting Sensors Where They Can Measure Correctly
Sensor field of view, target distance, shielding, surrounding metalwork, vibration, contamination, and cable routing should be considered during installation.
A sensor that is electrically correct can still perform poorly if its mechanical placement does not match the intended measurement.
