ESP32 GS1 Stackable Barcode + QR Code Reader – Upwork

Hi,

We have a ESP32 system, this one: https://www.aliexpress.com/item/32931586411.html

With it, we have a camera: https://www.aliexpress.com/item/1005001463190721.html

We need code to be able to instantly recognize all of the common Barcodes INSTANTLY, anything above 20ms would be considered too slow. Once the barcode is detected it will be sent using web-sockets.. Any error or reconnection protocols for websockets needs to be included.

We are open to purchasing other ESP32 systems and other cameras.

This is the list of barcodes that are REQUIRED to work, this is not an exhaustive list, and we want it to be able to accept any common retail barcodes.

(Some redundant barcodes in the list below, just to make sure we don’t miss any).

Hourly Range: $80.00-$150.00
