Variable rate prescription controller

Variable rate prescription controller

I built this sophisticated controller to turn on/off a planter DuoRate population controller based on one's location in a field. Controller can be used to turn on/off any device via its relay. Original use was to lower population when planting outside pivot irrigation areas at the corners of fields. App displays image of field and one's location. Also the prescription area to activate the relay. Map can be created from Google Earth on the tablet. Prescription can be made on the app with rectangular and circular markup tools. Internet access is not required for operation. App tracks application by grower, farm, and field. Application data can be exported for mapping. Price is subject to modifications desired.
