Hi,
I have a proximity ultrasonic sensor used to control a weeding device. I am using the sensor to detect the differences of plant heights. Plants are weeds and crops, I want basically to kill weeds and avoid damaging to crops by the device. The crops are higher that weeds, so I am using LabVIEW with USB DAQ 1208FS to compare the different heights. My sensor is located in front of the device in about 20 inches. When it starts reading the first plant (weed) the device will act immediately and kill it. When it gets to the second plant (crop), the device will act on the first plant which means skip some weeds as the sensor read crop. This way I might kill crops along with weeds or skip weeds. Is it possible to store or delay the sensor data till the weeding device get to the required target? Thanks!
