PRODUCT DESCRIPTON
The LRF0105C small laser rangefinder module is a precision optoelectronic device that emits a laser to the target and calculates distance information based on the laser's flight time. This laser rangefinder module communicates through a UART (TTL 3.3V) interface and features outstanding performance, simple operation, compact size, lightweight construction, and low power consumption.
