The TC25-1200 Long Distance Measurement Sensor is a compact laser ranging module with a 905nm Class I laser. It measures from 3 to 1200m (@70% reflectivity) with accuracy of ±1m (for <200m) or 0.5% (for >200m), a blind zone of only 5m, and 0.1m resolution. It operates on 3.3V–5V, features UART TTL interface, works from -20°C to 50°C, and measures 47×φ25mm, weighing 15g. Ideal for drones, robotics, and industrial distance measurement.
