LR2000E2 High-Precision Laser Ranging Module, 4m-2000m Long Range Laser Distance Sensor, 905nm Laser Rangefinder Module, Compact Lightweight Design

The LR2000E2 is a high-precision, compact laser ranging module designed for demanding measurement applications. Operating at a center wavelength of 905 nm, it delivers reliable distance measurements across a range of 4 m to 2,000 m with impressive accuracy — within ±1 m for distances up to 400 m and within 0.4% for distances beyond that. The adaptive ranging frequency of 2–10 Hz ensures fast, responsive updates, while the valid measurement rate exceeds 98% at close range. Weighing approximately 10 g and measuring just 25.65 mm × 13.05 mm × 24.6 mm, this module is ideal for integration into handheld devices such as night vision equipment, thermal imagers, telescopes, and laser illuminators. It also suits perimeter security, aviation, railways, law enforcement, power line inspection, and outdoor sports applications. Featuring a UART-TTL communication interface with a baud rate of 115200 bps and a supply voltage of 3.3–5 V, it supports both single-shot and continuous measurement modes. Secondary development is made easy with included test software and an interface protocol document.
