CanGrow
A simple DIY plant growing system (for cannabis).
WORK IN PROGRESS
Motivation
I want to build a simple grow system, which I can power by my off-grid 12V solar system. So this project is limited to a small 40x40x120 tent for one plant with a 50W 12V grow LED light.
As I did it for my solar system, the measurements of this project will be shown on my website. For that a REST API is planned.
I want to automate as much as possible which makes sense and is easy to build.
Features / ToDo List
- Measure values ✅
- Humidity ✅
- soil moisture ✅
- temperature ✅
- water level for water tank ✅
- LED grow light control (on/off, dimming, max. 12V 50W load ) 🔵
- You can of course use a relais as well, if you want to drive 220V lights
- fan control (on/off, (PWM?) max 1A) 🔵
- pump control for automatic watering (max 1A) 🔵
- Web UI and REST API for data and controlling 🔴
- simple web ui
- Send notifications with web call (e.g. for mastodon)
- predefined grow profiles
- persistend data
- Start of Grow
- day of grow
- grow profile
- watering amount per week
- light cycle
- wifi settings
- settings in general
- Easy to build and use for beginners (i hope so!) :large_blue_circle
- PCB layout to order from manufacture (jlcpcb or pcbway) ✅
- easy to build up on a perfboard 🔵
- easy to etch pcb 🔵
- easy to access and modify
- low cost as possible!
✅ Done - 🔵 In Progress - 🔴 ToDo
Parts used
-
ESP8266 D1 mini
-
DHT11 humidity and temp sensor
-
I2C soil moisture sensor: https://github.com/Miceuz/i2c-moisture-sensor / https://eu.robotshop.com/de/products/i2c-soil-moisture-sensor
- the I2C module is for some people too expensive, I plan support for those cheap capacitive sensors: https://www.az-delivery.de/products/bodenfeuchte-sensor-modul-v1-2
