The L1-40 TTL UART Laser Distance Sensor Module is intended for embedded integration where the host system handles power, protection, and mechanical mounting. It outputs distance data via TTL- UART  output , enabling direct firmware integration with microcontrollers and embedded controllers.

With 1 mm resolution, repeatable performance, and an absolute accuracy model of ±(1 mm + D×0.5‰), the module supports automation tasks such as AGV distance feedback, positioning reference, and equipment travel monitoring. Multiple serial protocol options (Modbus RTU / ASCII / HEX) simplify integration into different control architectures.

For outdoor or harsh environments, environmental protection should be implemented at the system level (enclosure/cable/harness design), as the module itself is not an IP-rated sealed sensor.

Applications

• Embedded distance measurement systems
• Robotics and autonomous equipment
• Smart devices and intelligent terminals
• OEM laser ranging modules
• Position feedback and displacement control
• Small target detection and monitoring
• Custom laser measurement solutions
• AGV / AMR Distance Feedback
• Industrial Positioning / Stroke Monitoring
• System-Level Enclosure for Field Use

Application Notes

• Designed primarily for embedded and indoor applications.
• For long-range measurement (especially 80 m), reflective targets improve accuracy and stability.
• Performance may be affected under strong outdoor sunlight.
• External housing or protection is recommended for harsh environments.
