Solution

LiDAR application solution for smart distance triggers

Use target distance or distance change to trigger lids, capture, status reporting, or device actions.

Smart device using LiDAR distance change to trigger an action

Scenario

Application scenario

A smart trigger converts continuous distance into a business event. LiDAR provides measurements and status; the controller owns thresholds, duration, debounce, authorization, networking, and fault handling.

Engineering problem

One threshold can misclassify passers-by, jitter, or invalid data as an event.
Targets, mounting positions, and environments need different trigger zones.
Sensor, controller, and network outages need defined fallback behavior.

Why LiDAR

Continuous distance lets the controller define multiple zones, trends, and duration instead of a single fixed switch point.

Workflow

Translate the business action into a target, distance zone, and trigger condition.
Select and mount by space, range, interface, and environment.
Implement filtering, thresholds, duration, and debounce in the controller.
Validate false triggers, no-return data, disconnects, and recovery.

Technology comparison and selection

Dimension	Condition	LiDAR	Alternative	Alternative performance	Conclusion
Configurable distance event	The action depends on a distance zone, change, or duration.	Provides continuous distance for multiple zones and dynamic rules.	Photoelectric or proximity switch	Fits fixed-point presence triggers with simpler output and rules.	Consider LiDAR for continuous distance or multiple thresholds; compare cost and complexity for simple fixed triggers.

Product selection guide

Current material supports 3 candidates. Review product facts, rationale and boundaries together.

Model	Key product facts	Best fit and rationale	Operating boundary	Product details
TF-Luna	Output data Single-point Distance Value Measuring range 0.2 ~ 8 m Interface UART, I/O, I²C Protection Without enclosure	For short-range, low-power approach or presence triggers needing one detection point.	Check the 0.2–8 m range, target reflectivity, threshold and hysteresis; handle point blind zones and occlusion in the real site.	View product
TF02-Pro	Output data Single-point Distance Value Measuring range 0.1 ~ 40 m Interface UART, I/O, I²C Protection IP65	For devices whose trigger point is farther away and needs a 40 m-class range or higher update rate.	Do not equate headline range with trigger reliability; validate interface, target surface, mounting angle, thresholds and failure strategy on site.	View product
TFmini Plus	Output data Single-point Distance Value Measuring range 0.1 ~ 12 m Interface UART, I/O, I²C Protection IP65	For trigger devices within 12 m that need IP65 and a wider single-point field with UART, I²C or I/O.	The wider field may include the background; validate target entry and exit, jitter, ambient light and false-trigger handling.	View product

Installation and integration

Cover the real target zone, implement filtering, thresholds, duration, debounce, and fault states in the edge controller, then connect upper systems.

Operating limits

Do not reuse one trigger threshold across devices. Validate targets, light, contamination, sampling, networking, and recovery per task.

FAQ

Frequently asked questions

Is one distance threshold enough for a smart trigger?

Usually not. Combine zones, duration, debounce, data status, and fault recovery to avoid false events from passers-by, jitter, or invalid data.
