This document discusses a project to monitor beehives using low-cost sensors and a Raspberry Pi computer. It describes how the presenter got involved with studying declining bee populations and working with a researcher who wanted hive monitoring. An inexpensive system was built using a Raspberry Pi, temperature and humidity sensors, solar power, and Ruby programming. The system provides online access to hive data. The presenter encourages others to get involved in open source projects that support social causes like bee research.
