There is a lot of room for improvement, and I’m looking forward to extending the GardenPi’s capabilities. I’ve watered my garden with a Raspberry Pi.
#Opensprinkler log file install#
Install install/init.d to /etc/init.d/god and follow instructions in that file.Power up the Pi and your 12V power supply.Connect the solenoid between water source and soaker hose, taking note of the directional arrow on the solenoid and using the adapter to connect the male end of your garden hose to the input on the solenoid.
Build out breakout board (see schematic below).Modify the parameters (forecast.io API key, timing info, etc.) in environment.rb.Pull the garden_pi_waterer repository and bundle install to install dependencies.Install Raspbian and configure WiFi access.High tech weather resistant case (aka medium sized Tupperware container).Assorted electronics (breadboard, resistors, wires, LED).A female hose swivel adapter to connect your garden hose to the solenoid.Solenoid for turning on the soaker hose.
Soaker / Drip hose throughout the garden.I’ve also learned that I’m not the only one doing this kind of project with the Raspberry Pi I’ve included links to other projects at the end of this post.
#Opensprinkler log file how to#
I’ve learned a lot in the last few weeks from building this project - a little bit more about basic electronics, how to solder, how to draw up schematics, and the joy of building actual gizmos that serve a purpose. Better sensors, form factor, time lapse, and user interface are all things that I’ll be looking at for future versions. The sensor data could be made available via an onboard website or mobile application. Based on that information, the GardenPi will be able to make better watering decisions. If there is less than a 50% chance of rain, the GardenPi will water for a short duration.įuture phases (already underway) will include sensors for temperature, soil moisture, light, and humidity. The script looks up the forecast using the Forecast.io API. I’ve written a simple script that wakes up at 10PM, determines the likelihood of rain, and waters accordingly.
Phase 1: Timer and Forecast-Based Watering The goal: An automated watering system that can use the weather forecast, soil, light, and temperature sensors to keep my garden looking great all summer. For this project I wanted to do better than just a glorified timer. I had a wifi-enabled Raspberry Pi laying around and decided to put it to good use. OpenSprinkler is an open-source Internet web-based sprinkler timer / controller built upon the Arduino platform. This spring’s project: monitoring and watering my garden. The application allows you to automatically detect and control your OpenSprinkler irrigation system(s). Like any good “lazy programmer,” I’m always looking for ways to automate.
