AgroSentinel Field

AgroSentinel Field is a phone-photo screening aid for aflatoxin in stored maize. Farmers and small traders have no cheap way to check stored grain. The user uploads a photo of a lateral flow test strip, selects grain type, storage humidity, and months in storage, and the app returns a reading, a decision, and advice in Nepali and English. It is a screening aid, not a lab test. The model reads the control and test lines, and a simple rule maps the reading to a decision. Limitations: the rule is a placeholder, graded contamination levels are future work, and accuracy has been tested on only a small set of photos. Future work includes SAM segmentation of the strip, tuning the rule on field data, and supporting more strip brands.
