Part Numbers


Features of the A06 module include millimeter resolution, 25cm to 500cm range, reflective construction and various output options: PWM pulse width output, UART controlled output, UART automatic output, switching output, RS485 output.

According to different characteristics and advantages, the module is divided into two series:


A12A series, mainly used for plane ranging;

A12B series, mainly used for human ranging.


The A12A series of modules are mainly used for plane distance measurement; it can perform targeted measurement on plane objects and can measure long distances, small angle, and high accuracy. The farthest measurable measuring range of a flat object is 500cm.

The A12A series of modules are mainly used for human body distance measurement; it is sensitive to human body detection, and the human target measurement is more stable, high stability of objects measured . It can measure the upper body of the human body stably within 350cm. Measuring the farthest measuring range of flat objects
is 500cm.
