Spy Fly is a monitoring system that uses modern technologies to allow the farmer to monitor the phytosanitary conditions of their crops, directly from their smartphone or other device.  Equipped with a practical and resistant modular casing, SpyFly is able to attract harmful insects, using the combined action of colour attraction and pheromones, allowing them to be captured on an adhesive surface.  At intervals, SpyFly photographs the adhesive paper, transferring the images to a cloud platform, where they are processed and analyzed by algorithms, thus identifying harmful insects. SpyFly also measures meteo-climatic parameters, useful for developing predictive models on the spread of harmful agents.
