SPD1200N4 Laser Ranging Module, 905nm, 0.2m to 1200m Range, UART-TTL Interface, Compact High-Precision Laser Rangefinder Sensor

The SPD1200N4 is a high-precision, compact laser ranging module operating at a center wavelength of 905 nm. It delivers an impressive measurement range of 0.2 m to 1,200 m under standard conditions, with nighttime performance reaching up to 1,500 m. With a ranging accuracy of ±0.3 m at distances up to 100 m and a measurement accuracy rate of ≥98%, this module is built for reliable, real-world performance. The adjustable measurement frequency of 2–15 Hz (or 4–15 Hz adaptive) can be customized to suit your application. Featuring a UART-TTL communication interface with a default baud rate of 115,200 bps, it supports convenient secondary development and comes with dedicated test software and communication protocol documentation. The module operates on 3.3–5 V, weighs approximately 5 g, and measures just 21.3 × 9.35 × 16.7 mm, making it ideal for integration into handheld devices such as night vision devices, thermal imagers, and telescopes. It is also well-suited for border security monitoring, aviation, railway systems, law enforcement, and outdoor sports applications. Rated IP67 (inside lens cavity) and built to withstand temperatures from -20°C to +60°C.
