How does the WeedSeeker sensor work?
1. “Light emitting diodes” (LEDs) produce a combination of invisible infrared and visible red light which is projected onto the target approximately 2 feet below the sensor. 2. The light reflected from the target is captured by a detector at the front of the sensor. 3. Sophisticated electronics inside the sensor analyze the reflected light and determine when it matches the light reflected by green plants. 4. When green plant’s reflectance is identified, the sensor waits until the plant is under the spray nozzle and then triggers a fast-fire solenoid valve which sprays the plant.
