dJPoidas Watering System

dJPoida's automated garden watering system.

This is a simple project for activating a water pump that sits inside a small reservoir to regularly water my herbs because I'm a numpty and always seem to forget. Homemade pizza is much nicer with fresh Basil, Oregano and Chilli!

Dependencies

Arduino

The code for this project is written for the Arduino platform.

Blynk

This project leverages the Blynk IoT platform for remote management and reporting.

Instructions

• Clone the repo
• Copy the config_example.h to config.h and populate with your appropriate config values. Specifically:
  • blynkAuthToken[]
  • ssid[]
  • pass[]
• Set your board config properly before uploading or the pins and flash won't work properly:
  • LOLIN(WEMOS) D1 R2 & Mini
  • Flash Size: 4M (1M SPIFFS)
• Install Blynk on your control device (mobile / tablet) and load the control app by scanning the QR Code

Blynk App

This is what the Blynk control app looks like

To start with the Blynk app I created, scan this code in blynk

Schematic

Note: the Wemos D1 R2 Fritzing part isn't perfect so this schematic is mostly representative.

Workflow

SPIFFS Cache file

The data stored in SPIFFS is nothing complex and simply assists in the determination of next watering time.

• Line 1: Date last executed watering routine (stored as a long formatted YYYYMMDD)
• Line 2: Time of day last executed watering routine (stored as a long in 24hr format HHMMSS)

20200119
160212

The above data indicates that the watering routine was last executed at 4:02:12pm on January 19, 2020.
