Automated Weed Finding for Precision Agriculture

Sony X AI AgTech Challenge

May 19, 2025

At the Sony X AI AgTech Challenge, we built a first-place Raspberry Pi camera prototype for detecting weeds in the field and mapping dense areas in software, helping growers target pesticide usage instead of blanket spraying.

What I did

  • Built the Raspberry Pi camera vision system.
  • Built the weed detection to heat map data pipeline.
  • Researched grower viability and go-to-market.
  • Won first place.
