ERDI Laser SPD1200M2 Laser Ranging Module, 905nm 0.2-1200m (1500m Night) High Precision ±0.3m, 2-15Hz Refresh Rate IP67 Waterproof UART-TTL, Mini Laser Distance Sensor

ERDI LASER SPD1200M2 Mini High-Precision Laser Ranging Module – Ultimate Distance Measurement Solution for Professional & Outdoor Applications Introducing the ERDI LASER SPD1200M2 Laser Ranging Module, a lightweight, compact, and high-performance distance measurement sensor engineered for seamless integration into all your handheld and professional devices. Operating at a 905nm laser wavelength with an IEC Class I laser safety rating, this module delivers reliable, eye-safe measurement performance with a range of 0.2m to 1200m (up to 1500m in nighttime/low-light conditions) and industry-leading precision of ±0.3m (≤100m). Designed for versatility and durability, the SPD1200M2 features a 2-15Hz adjustable refresh rate (adaptive 4-15Hz mode available) and a 98%+ measurement accuracy rate, ensuring stable, real-time distance data for fast-moving or static targets. Its ultra-compact size (7.7×15.3×27.85mm) and lightweight design (only 6g) make it the perfect choice for integration into night vision devices, thermal imagers, telescopes, laser illuminators, and handheld outdoor gear—no bulky equipment required. Equipped with a UART-TTL communication interface (default 115200 bps, customizable baud rate) and compatible with dedicated ERDI-Tools test software, this module supports easy secondary development, making it ideal for DIY projects, professional device modification, and industrial applications. The IP67 waterproof rating (inside lens cavity) and rugged construction deliver superior performance in harsh environments: it withstands 1000g/ms shock resistance, 5-50-5Hz vibration resistance, and operates in a wide temperature range of -20°C to +60°C (storage: -30°C to +70°C). With a 3.3V-5V wide voltage supply, fast startup time (≤200ms), and low average power consumption (≈0.45W), the SPD1200M2 balances high performance with energy efficiency—perfect for battery-powered handheld devices. It supports single and continuous measurement modes, and for low-reflectivity targets, the module automatically repeats measurements to ensure stable, accurate data output via serial interface in a standard hexadecimal format. Whether you’re building custom outdoor gear, upgrading thermal imagers/night vision devices, or developing professional ranging solutions for border security, railway systems, smart water conservancy, or aviation, the ERDI LASER SPD1200M2 Laser Ranging Module is the reliable, high-precision choice for every application.
