About the Project

Plants Care is a system that automatically takes care of plants.
It controls soils moisture and trigger watering based on configured rules.

Built With

• Arduino
• NodeJS & TypeScript

Getting Started

Hardware Setup

• NodeMCU Lol1n v3 ESP8266 (ESP-12E) Wi-FI CH340: Documentation
• Analog multiplexer 74HC4051_8-Mux: Data sheet
• Soil moisture sensor: Funduino Data sheet
• Water pump: to do
• Battery: LiFePO4 18650

Arduino

1. Rename ./arduino/Secrets.h.dist to ./arduino/Secrets.h and replace its values.

#define PUSH_GATEWAY_BASEURL "https://ip:5091/metrics/job/plantcare/instance/a"
#define PLANTS_CARE_BASEURL "https://ip:5080/api/watering/a"

a at the end of the URLs represent a microcontroller, name it as you want.
You can install how many microcontroller as needed.

2. Compile & Upload (see Makefile)
3. Bury soil moisture sensors in plants
4. Plug a battery
5. ???
6. Profit!

Box, Connectics & PCB

To do

Software Setup

Using Docker-Compose

docker-compose.yaml

services:
  plants-care-api:
    image: deuzu/plants-care-api:alpha
    restart: unless-stopped
    environment:
      DATABASE_HOST: plants-care-database
      DATABASE_NAME: ${DATABASE_NAME}
      DATABASE_USER: ${DATABASE_USER}
      DATABASE_PASSWORD: ${DATABASE_PASSWORD}
      DATABASE_CONNECTION_TIMEOUT: ${DATABASE_CONNECTION_TIMEOUT}
      DATABASE_CONNECTION_LIMIT: ${DATABASE_CONNECTION_LIMIT}
    ports:
      - 5080:80

  plants-care-database:
    image: mariadb
    restart: unless-stopped
    environment:
      MARIADB_RANDOM_ROOT_PASSWORD: 1
      MARIADB_DATABASE: ${DATABASE_NAME}
      MARIADB_USER: ${DATABASE_USER}
      MARIADB_PASSWORD: ${DATABASE_PASSWORD}
    volumes:
      - plants-care-database:/var/lib/mysql
      - ./database-init.sql:/docker-entrypoint-initdb.d/1-database-init.sql

  prometheus:
    image: prom/prometheus
    volumes:
      - ./prometheus.yaml:/etc/prometheus/prometheus.yml
      - prometheus:/prometheus
    ports:
      - 5090:9090

  push-gateway:
    image: prom/pushgateway
    volumes:
      - pushgateway:/data
    ports:
      - 5091:9091

  grafana:
    image: grafana/grafana
    volumes:
      - grafana:/var/lib/grafana
    ports:
      - 5030:3000
      
volumes:
  plants-care-database: ~
  prometheus: ~
  pushgateway: ~
  grafana: ~

prometheus.yaml

global:
  scrape_interval: 30s
  evaluation_interval: 30s

rule_files: ~

scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: [localhost:9090]

  - job_name: push-gateway
    static_configs:
      - targets: [push-gateway:9091]
    honor_labels: true

Consider using a reverse proxy like nginx-proxy/nginx-proxy or traefik/traefik.

Roadmap

• How to waterproof moisture sensor? Silicon?
• Power consumption savings with deep sleep: gist examples
• Handle HTTPS properly
• automatic watering e.g.
• PCB how to & Phil's lab youtube channel
• Box and connectics
• Solar panels
• Rewrite it in Rust + Tonari examle

Development

Arduino

cd arduino & make

Arduino CLI

To find the board:

arduino-cli board list

If error "Could not open serial port /dev/ttyUSB0" is encountered:

sudo usermod -a -G dialout <username>
# or
sudo adduser <username> dialout

Example soil moisture level sent:

cat <<EOF | curl --data-binary @- localhost:5092/metrics/job/plantcare/instance/a
# HELP moisture level in percentage
# TYPE moisture_level gauge
moisture_level{sensor="0"} 12
moisture_level{sensor="1"} 74.605713
moisture_level{sensor="2"} 42
moisture_level{sensor="3"} 654
EOF

API

cd api && make
