Overview
Meskernel PTFG-2000 is a laser rangefinder sensor module designed for long-distance digital distance measuring. This laser rangefinder sensor module uses pulsed laser technology (905 nm, Class 1) and delivers ±1 m accuracy with 0.1 m resolution across outdoor applications. Typical supply is DC 3.3 V with low power consumption, and TTL output is standard; RS232/RS485 options and UART (115200 bps default) are supported for integration.
Key Features
- Long-range measurement up to 2000 m with ±1 m accuracy
- Fast measurement response; ~1 s maximum single measurement time
- Pulse ranging technology for high precision and stability
- Easy integration: compact size and light weight (66 g)
- Interfaces: TTL (standard), optional RS232/RS485; UART default baud rate 115200 bps
- 905 nm Class 1 laser emission and reception
- Multi-functional applications: golf, shooting, bird watching, UAV ranging, monitoring, vehicle anti-collision
