An Integrated Multi-Sensor System for Remote Bee Health Monitoring

Over 75% of the world's food crops depends on pollination and in particular by the inestimable value of the service provided by bees. Besides, the bee colony health is a good indicator of the quality of the environment and it is strongly affected by many aspects such as beekeepers' management practices, policies adopted for cropping and land use. However, the climate change, the intensive agriculture, pesticides, biodiversity loss, Varroa mites and pollution are the leading cause of bees death world wide. The role of beekeepers is of extremely importance to mitigate this damage. Apiaries are usually located in remote environment an require frequent visit by the beekeepers. Indeed, the beekeeping sector lacks of suitable tools for risk assessment and decision making that can be used by stakeholders. Smart monitoring systems assessing the health of the colony and the honey production would be beneficial for such community. In this work, we present a prototype of an embedded multi-sensor system for beehive monitoring with the aim of providing a simple solution to beekeepers. Indeed, the proposed system do not require modification of the beehive and it is compact enough to be simply inserted in the brood box. It measures the vital parameters of the beehive, such as temperature, weight, humidity and CO2 concentration. It exploits the low power communication protocol LoRaWAN for the data transmission. The collected data are made available to the beekeeper through a web application. We show the effectiveness of such compact, non-invasive embedded system with its installation in an apiary.
