Boolean Trigger

Overview

The Boolean Trigger node only passes data through when its trigger input is true. It acts as a gatekeeper, typically placed in a flow to control when data processing occurs.

Use Boolean Trigger when:

• You want to process an image only when a specific object is detected.
• You want to trigger a flow action via a button press or external signal.

💡 Tip

When the trigger is false, the data is completely blocked from proceeding down the flow path.

Inputs

Name	Type	Description
input	any	The data to be passed or blocked.
trigger	bool	Controls the gate; true passes data, false blocks it.

Outputs

Name	Type	Description
output	any	The input data, returned only when the trigger is true.

Parameters

This node does not have any configuration parameters.

Example

Gated Inspection

An image is captured continuously, but you only want to run analysis when a sensor confirms a part is in position.

Configuration:

• This node has no configurable parameters.

Result: When the trigger signal from the sensor is true, the image is passed to the output. When false, no data is sent to subsequent nodes.
