Add to wish list

The SEN0512 is a barcode and QR scanner reader module. This 2D scanner is able to automatically sens and scan when a code has been presented to it and, with CMOS image recognition, it's able to recognize various codes and QR codes. 

This scanning module reads barcodes or 2D codes with a scan speed of 15m/min. With small size and high-efficiency recognition, it is easy to be integrated into various industrial equipment and applications.

The module is equipped with a 0.3megapixel camera and auxiliary lights, white light illumination, and red light focusing, which makes it able to effectively identify codes in low-light environments.
