LR1000C4 Laser Rangefinder Module, 905nm Laser Ranging Sensor, 1000m Laser Distance Measurement Sensor

The LR1000C4 is a new-generation, high-precision, compact laser ranging module designed for demanding measurement applications. Operating at a wavelength of 905 nm, it delivers reliable ranging capability from 13 ft to 3,281 ft (4 m to 1,000 m) with an accuracy of ±1 m for distances up to 1,640 ft (500 m). The adaptive ranging frequency of 3–10 Hz can be customized to meet specific requirements. Weighing just under 0.6 oz and measuring approximately 1.13" x 1.20" x 0.82", this lightweight module is ideal for integration into handheld devices such as night vision devices, thermal imagers, telescopes, and laser illuminators. It also supports perimeter security monitoring, aviation, railways, law enforcement, and outdoor sports applications. Featuring a UART-TTL communication interface with a baud rate of 115,200 bps, it supports secondary development with included test software and protocol documentation. The module operates across a wide temperature range of −4°F to +131°F and carries an IP67 protection rating inside the lens cavity, ensuring durability in challenging environments. With a valid measurement rate of ≥98% and a false alarm rate of ≤1%, this module delivers consistent, dependable performance.
