How to build 3rd party software adapters for hardware you can’t afford
Developing Adapters For 3rd Party Products
GreenThumb is working to build a platform that connects growers to the systems they’re already comfortable using today. This blog post will read a bit like a tutorial on how to DIY your own dosing system.
Peristaltic Dosing Pump Solution
I’m not trying to compete with commercial dosing system here, but I will be demonstrating a cost effective solution to control the mixing of solutions autonomously. In doing this we also define the features and components required for a base adapter than can be augmented to connect with any 3rd party offering. Enough of the diatribe, let’s jump in, first to assess the industry standard solution.
Theirs $3300: For Commercial Production Deployments
Connect pH Controller $500
This device is a commercial grade IoT pH control unit with liquid temperature and pH probes and a peristaltic pump for dosing pH buffer solution at a rate of 10 ml per minute.
Microdoser $800
Macrodoser $2000
Ours $400: For Testing and Development Purposes

Conclusion
For a commercial cultivator you’re going to want to devise a professional solution using brand products as shown below.
Once you have your setup or once you’ve build your own GreenThumb will be ready to integrate providing automated controls and notifications with visual and sensory insight into your systems.
If you have any questions or are interested in the project or using my open-source packages, feel free to leave a comment or ping me on LinkedIn or Twitter, I will be responsive.
GreenThumb is also seeking early clients, partners, and initial funding. Yes, I did the work and paid for this all on my own.
