This laser range sensor can be used to detect objects in 4~400 cm with ±2 cm accuracy. With 3 measurement modes supported, it is well applicable to various detection scenarios like security gate detection, access control systems, security alarm devices, smart trash cans, smart cars, or robots for obstacle avoidance.

The sensor metal black shell adopts a threaded barrel design and its probe comes with an optical cover. The integrated design makes the product able to effectively filter optical interference, waterproof and shockproof. The sensor uses an invisible laser and there is a voltage regulator circuit inside the module. It operates at 5 V ~ 36 V and has stable performance with UART/ RS485 output. The sensor has an alarm output line that will be triggered to output Low steadily when the measurement distance is smaller than the user-set threshold.

Note: The data will be unstable when measuring black objects.
