905nm Laser Rangefinder Module 1km
DESCRIPTION
Erdi Tech's newly developed laser ranging module. This 905nm laser ranging module employs Time-of-Flight (TOF) technology to achieve high-precision distance measurement (5-1000m range) by calculating laser beam round-trip time. Featuring direct TTL-to-MCU connectivity, compact form factor (<10.5g), and low power consumption, it is suited for autonomous systems, surveying equipment, and industrial automation. Its extremely small size makes the product very popular.
