DFRobot - Mini Laser Distance Range Sensor (4m, I2C, IP67)

This laser distance ranging sensor has a compact size, comparable to the size of a fingernail, and a measurement range of up to 4m. It is specifically designed to address the issues commonly found in distance sensors on the market, such as large size, slow response time, and poor installation adaptability.

It boasts a range of advantages including small size, minimal blind zone (Measurement accuracy: ≤25cm@±1cm, >25cm@±S*4%cm), fast response time (19-38ms), high installation adaptability, dust and water resistance (IP67), long lifespan, and high reliability.

The sensor outputs data through an I2C interface, which allows users to easily integrate it with Arduino IO expansion boards.

It finds widespread applications in various fields, including smart furniture with motion sensing capabilities, home security systems, intelligent detection systems, smart control systems, robot obstacle avoidance, and object proximity and presence detection.
