ics hardware esp32 ignition

automated garden

A garden-scale SCADA system built on ESP32 microcontrollers and Inductive Automation's Ignition platform. Designed as a hands-on ICS/OT credential and a real working system to water my plants.

overview

I didn't want to have to travel to my grandmother's house (where the garden bed lives) every other day for watering and I wanted to remove the guesswork, so I thought: "I'll get some mosture sensors and pumps, how hard could it be?" As a bonus I figured this would be a great way to dive into Ignition and SCADA systems.

stack

ESP32 — sensor nodes, WiFi connectivity
Ignition — SCADA platform, HMI dashboards
MQTT — messaging protocol between sensors and platform

what I learned

So far, I have learned significantly more about circuitry, the differences between available current and draw and the self limiting properties of Motor EMF. I really like physics and science, learned as much as I could about it as a kid and teen, and haven't had much natural science exposure in Columbia since my coursework is mainly math and CS. It's nice to be in the realm where they intersect. July
