The USER-PA project implements a technological architecture for precision agriculture (precision fruticulture and viticulture). Plant data is acquired from crown and fruit sensors that run by means of autonomous platforms and are connected by wireless sensor networks (WSNs). The acquisition of information is done in a spatially resolved farm management information system (FMIS). Economic evaluation was integrated into the project from the beginning. The expected outcome of an integrated system that incorporates a number of sensing techniques and a web-based FMIS that enables farmers to manage their crop was achieved with demonstration of the canopy–fruit sensor and FMIS. USER-PA showed the potential of providing farmers with quantitative information to decide upon optimal harvest timing and irrigation, while fruit quality and production remained effective. Partners’ comprehensive collaboration during field campaigns acted as a project interworkshop and led to integration and assimilation of sensor data into the FMIS. The robot prototype developed by the USER-PA project is the only autonomous tractor in the UK that meets all current health and safety standards and complies with the new ISO standards. The website developed can take data from the tractor into the cloud in real time (http://pafmis.com/).
