From the project

This repository is an experimental greenhouse monitoring and control project built around an ESP32-class controller. It combines environmental sensors, relay-driven actuators, MQTT/Node-RED connectivity, over-the-air updates, persistent setpoints, and an Edge Impulse anomaly mode

This repository is an experimental greenhouse monitoring and control project built around an ESP32-class controller. It combines environmental sensors, relay-driven actuators, MQTT/Node-RED connectivity, over-the-air updates, persistent setpoints, and an Edge Impulse anomaly model. It also contains the project's firmware history and KiCad hardware designs.

The project is a prototype, not a finished safety controller. The firmware and PCB directories contain several generations with different assumptions. Start with code section/final/final.ino for the most integrated implementation, then…

External: common questions

How big is the External PCB?

The External measures 25.1 × 35.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the External?

9 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the External design files?

From the mohamed1920said/Greenhouse_edge_AI repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the External design in my own project?

The repository has no license, so all rights stay with mohamed1920said. Use it as a reference, and ask the author before reusing the design.
