About the Sapflow gauge PCB

Sapflow gauge is an open source PCB design by dotmote, published on GitHub. It is a 2-layer board measuring 25.2 × 22.8 mm, with 8 components from 7 distinct parts.

It belongs with the iot & wireless, dev boards & breakouts and sensors designs in this gallery.

From the project

Opensource Sapflow

So you want to measure sapflow 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?"

To build the gauge, you'll need: (1) the PCB; and (2) the components.

Visualize your hard-earned data with this Observable notebook.
