Meskernel PTFG-1500 Long Distance Pulse Laser Sensor - USB to TTL Interface

The PTFG-1500 operates from a 3.3V to 5V DC power supply. Its serial communication interface (USART/RS232/RS485) operates at 3.3V logic levels, making it directly compatible with most 3.3V microcontrollers like the Raspberry Pi or ESP32. For 5V systems, a logic level converter may be required for the data lines.

The module supports multiple industrial serial communication protocols via its integrated USB to TTL bridge. It is configurable for standard USART (TTL serial), RS232, and RS485 interfaces. The default baud rate is 115200 bps, and the output data format follows a standard distance reporting protocol for easy parsing.

Yes, the laser is eye-safe. It uses a Class 1, invisible 905nm pulsed laser with an output power of less than 1mW. The effective measurement range is from 5 meters up to a maximum of 1500 meters, with a stated accuracy of ±1 meter under typical conditions.

For use with a PC, simply connect the module's USB port directly. For microcontroller use (e.g., Arduino), connect the sensor's TX/RX pins to your board's serial pins, ensuring logic level compatibility (3.3V). Power the module with 3.3V to 5V DC applied to its VCC and GND pins. No external drivers are needed for basic serial communication.
