# 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 :white_check_mark:
- Humidity :white_check_mark:
- soil moisture :white_check_mark:
- temperature :white_check_mark:
- water level for water tank :white_check_mark:
- LED grow light control (on/off, dimming, max. 12V 50W load ) :large_blue_circle:
- You can of course use a relais as well, if you want to drive 220V lights
- fan control (on/off, (PWM?) max 1A) :large_blue_circle:
- pump control for automatic watering (max 1A) :large_blue_circle:
- Web UI and REST API for data and controlling :red_circle:
- 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!) :red_circle:
- easy to build up on a perfboard
- easy to etch pcb
- easy to access and modify
- low cost as possible!
:white_check_mark: Done - :large_blue_circle: In Progress - :red_circle: 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
- 50W LED 12V full spectrum grow light: https://www.ebay.de/itm/354322466159
- MOSFETS (some i have fyling around, IRF3205, IRF3710, BUZZ11...)
- 12V 4W water pump set https://www.ebay.de/itm/394413649692
