Farm Optix field nodes

01 · CHALLENGE

Low-cost environmental sensors that look fine on a datasheet often drift or fail under humidity, dust, and monsoon conditions.

02 · ROLE

Builder / technical lead — sensor selection, field durability decisions, and public learning notes.

03 · DESIGN DECISIONS

• Prefer field durability evidence over raw datasheet accuracy.
• Swap to BME280 when humidity ingress and drift made the original sensor unusable.
• Publish the pivot so future collaborators see how decisions actually change.

CURRENT STATE

Experimental field work with public pivot documentation. No customer counts or yield-impact claims are published here.

WHAT I LEARNED

• Datasheet specs assume lab conditions; weight field reports from real deployments.
• I2C swaps are cheap at the wiring layer—the cost is recalibrating downstream thresholds.
