PROJECT TOPICAgri-Tech, Environment & Biotech
Selective Chemical Dispenser
A precision farming vision concept examining high-speed solenoid valves and embedded neural networks to detect unwanted weed species and apply micro-doses directly to weed foliage.
Targeted Herbicide Reduction
- ✓Targets chemical spray specifically at unwanted weeds rather than blanketing entire fields.
- ✓Explores millisecond solenoid valve opening times to spray only when weeds pass beneath nozzles.
- ✓Demonstrates significant chemical input reduction compared to broadcast spray booms.
The Engineering Challenge
Problem / Objective
Blanket field spraying saturates commercial crops in chemical herbicides, increasing farm operating costs and chemical runoff.
