Features of the A13 module include millimeter resolution, 25cm to 200cm range, reflective construction and severaloutput types: PWM pulse width output, UART controlled output, UART automatic output, switching output, RS485 output .

The characteristics and advantages of the A13 module are high sensitivity and small angle, that is, the module has a strong detection ability, and can identify objects with a small sound wave reflection coefficient or a small sound wave effective reflection area within the effective measurement range. It can be applied to waste bin . Suitable for waste bin fill level.

In addition,,Firmware filtering for excellent noise tolerance and clutter rejection.
