MRF designed a sprayer Bluetooth sensor which can be attached to field personnel sprayer guns. A sprayer mobile app is developed for smartphones and tablets to communicate with the Bluetooth sensor. By tracking the Bluetooth sensor on a sprayer gun, the sprayer mobile app uploads the GPS location and user actions to MRF web server. Users can view work completed on desktop computers, smartphones and tablets.
