AgXRP Pump & Soil Moisture Sensor Expansion Pack - DIY - Beta

Scale up your agricultural automation with the DIY AgXRP Pump & Soil Moisture Sensor Expansion Pack. Designed to combine with your existing AgXRP Starter Kit, this expansion allows you to add a completely independent watering zone to your smart farm. By adding a second pump and soil sensor, students can experiment with different plant types, compare watering schedules, and monitor varying soil conditions side-by-side.

Educator Discount Available: SparkFun and its partners are proud to work closely with the education community. We offer a significant discount on the AgXRP Starter Kit with an Educator account! Please contact support@sparkfun.com to get started.

Built for Growth

Because the XRP Controller on your main kit features multiple motor drivers and daisy-chainable Qwiic^® connectors, adding this expansion is incredibly straightforward. You simply build the second pump assembly, connect the additional soil sensor, and plug them directly into your existing controller.

This DIY version includes the essential hardware to build an additional planting zone, but does NOT include physical frames. We encourage you to use our provided open-source files to 3D print your own custom pump enclosure and mounting hardware:

• Automated Watering: A Hobby Motor with Encoder, Deep-Groove Ball Bearings, Latex Tubing, and an AgXRP Single-Pump Enclosure Frame can be used to add an additional peristaltic pump to your 3D-printed enclosure.
• Accurate Soil Monitoring: Adds a second SparkFun Qwiic Soil Moisture Sensor and a 500mm Flexible Qwiic Cable for real-time hydration tracking on your additional plant.
• DIY Structural Support: You will 3D print the AgXRP frames, enclosures, and pump to provide a stable (and potentially custom) foundation for your electronics during long-term experiments.

Looking to expand your setup? You can add up to three of these Expansion Packs to your base AgXRP Starter Kit, allowing you to automate and monitor four independent planting zones at the same time.

Collaborative STEM Ecosystem

To ensure this platform prepares students for real-world challenges, we partnered with organizations driving actual change in communities nationwide. This includes leading academic institutions such as Cornell University and the University of Idaho.

Because this is a Beta release, we are actively looking for educators, students, and community partners to help shape its future. Whether you want to pilot the AgXRP, contribute to curriculum development, or support broader outreach efforts, you are joining a growing community dedicated to building the future of food, one line of code at a time.
