Meskernel LDL-10 Laser Distance Sensor (1mm Accuracy, 10m Range) USB to TTL

The LDL-10 features a built-in USB to TTL converter, providing a direct UART (Serial) interface. This allows you to connect it directly to a computer's USB port or to the UART pins of a microcontroller (like Arduino or ESP32) using standard 3.3V logic levels for straightforward distance data reading.

The module operates on a 3.3V DC supply and consumes less than 60mA during active measurement. It is crucial to use a stable 3.3V power source; applying 5V directly to the logic pins may damage the sensor. The integrated USB interface can also provide power when connected to a PC or compatible USB port.

The LDL-10 offers selectable measurement frequencies of 3Hz, 10Hz, or 20Hz. The actual measurement time per reading can vary from 0.1 to 4 seconds depending on the target distance and surface reflectivity. Higher frequency modes provide faster updates but may impact performance at longer ranges.

Yes, the sensor uses a Class II red laser with an output power of less than 1mW, which is considered eye-safe for incidental exposure. However, as with all lasers, you should avoid staring directly into the beam and follow standard laser safety guidelines for your application environment.

While the laser phase technology offers good stability, performance can be affected by direct, intense ambient light (like sunlight) which can overwhelm the receiver. For optimal performance, it is recommended for use indoors or in controlled lighting conditions. The operating temperature range is 0°C to 40°C.
