Sap Flow Using the External Heat Ratio Method

So you want to measure sap flow in plants? You and me both, buddy. The goal of this project is to create an open-source, accurate, robust, low-cost, and low-power system to help answer the age-old question: "How is my plant doing?"

Take a look at the hardware and software sections for instructions on what you'll need to set up your own system and join in on improving the project.
