Overview
The Meskernel TC Series laser distance sensor module is a compact pulse ranging photoelectric range finder designed for long-distance measuring applications. This laser distance sensor module supports multiple communication interfaces (TTL/RS232/RS485/Bluetooth per model) and operates from a 3.3 V supply, delivering up to 1000 m measurement capability (model options 3–400/700/1000 m) with ±1 m accuracy and 0.1 m resolution. It is suitable for UAV distance measurement, security monitoring, and integration with optoelectronic systems.
