English to French Other Computers: Software

" Cameras will be attached using USB cables to the computer on the Yamaha Rhino. Custom software capable of processing the images to detect weeds, bare spots and blueberry plants in real-time will be able to send weed or plant triggering signals through a Labjack digital i/o and data acquisition device to the VRC. The VRC will have user programmable inputs such as a before and after distance buffer, delay time and ground speed correction. The VRC sends a signal to the LMC which will automatically adjust the flow rate based on the number of nozzles on at a specific time and also actuate the corresponding solenoid valve to spray agrochemical in the specific boom section where the weeds or plants have been detected."

Il s'agit d'un pulvérisateur à taux variable équipé de deux appareils photos numériques.
Je ne comprends pas le sens de la phrase "will be able to send weed or plant triggering signals" le système envoie des signaux lorsqu'ils détectent des mauvaises herbes?

D'avance merci !
