open source garden automation project The Brain The brain is where all the other modules come together. Physically the brain is mostly a couple of little boards and a lot of wires. The microcontroller we are using in this project is an Arduino board. The local circuit is actually the back end for each of the other modules. The main idea is that you have a board where you can put the "local circuit" part of each module. Supplies: (see the parts page)Arduino boardUSB cablejumper wires / lead wiresbread-board / proto-boardall parts for the local circuit for each of the modulesthe GardenBot software package The hardware side of the brain Creating the local circuit board Here you will be creating a circuit board where you can mount the local circuit portion of each of the other modules. Let's take a look at a potential setup with an Arduino board and a couple of breadboards. We start off by running the two power wires -- ground (0v) shown in black, and source (5v) shown in red.

How To, soil moisture, water valve, light sensor How To This section has various tutorials on the different components you might need to build a garden monitoring system. The entire how-to section is organized by modules -- each kind of sensor gets its own module. The overall concept is that you will generally have a microcontroller (like Arduino) hooked up to sensors (like soil moisture) and actuators (like a water valve). If we think of the whole system as a robot, then our microcontroller is our brain. Because of the long distances in volved in automation of even a small garden, some of the modules (like the soil moisture sensor) are bound to be physically far away from the brain. Throughout these tutorials I use the term local circuit. The Modules Running wires to remote modules To connect the various remote modules (like the control panel or the garden station) to the brain, you will need to run wires -- some very long wires. Probably the cheapest option is to purchase a roll of 6-strand phone wire (see the parts page).
Humidity and Temperature Sensor The Humidity and Temperature Sensor is an Arduino-compatible sensor board that carries an SHT21 digital humidity and temperature sensor from Sensirion. It has a 4-pin interface that can communicate directly with the analog pins on the Arduino. The SHT21 utilizes a capacitive sensor element to measure humidity, while the temperature is measured by a band gap sensor. Both sensors are seamlessly coupled to a 14-bit ADC, which then transmits digital data to the Arduino over the I2C protocol. Because of the sensor’s tiny size, it has incredibly low power consumption, making it suited for virtually any application. To optimize accuracy of temperature and humidity readings, the SHT21 sensor is placed at the tip of the board, isolating it from heat producing circuitry. The sensor can be placed in soil to measure moisture and temperature, which makes it ideal for using it in a garden or greenhouse. Board comes assembled with 4-pin male headers soldered on.

Growduino smart garden I've been toying with so many ideas of things to automate, but with the long days and an approaching 2-week trip and two young plants at home, I started working in earnest on a garden control project last night. "Growduino" seemed like the obvious name... ;D This is the simplest possible version-- just an automated watering system, with the nutrient solution pumped up from a reservoir in the tub with a submersible pump. Here's a shot on Flickr: from the description: The "growduino" smart garden project will, um, grow to include more sensors and controls, but watering on a schedule seems like a good starting point since I'll be leaving the rig alone for 17 days starting Friday. The program's main parameters are pump period (time between pumps) and pump duration. Note: the "plans" are in (roughly) increasing level of complexity/desirability-- not sure about aiming or CO2 scrubbing (?!)
Blog » Blog Archive » GardenBot Is Monitoring Your Garden GardenBot Is Monitoring Your Garden Davide Gomba — October 21st, 2010 Very interesting bottom-up product (but it’s not really a product, it’s more of an experience of nature-lovers and DIYers) do look after your garden: GardenBot is a garden monitoring system. I did… er, I mean hi. amazing story. via [gardenbot] Green Roof Growers: How to Make a Two Bucket Sub-Irrigated Planter (SIP) This is a simple, easy-to-do project that will let you grow your own food wherever there’s enough sunlight--on your roof, balcony, back steps, driveway, or vacant lot next door. It doesn't take any special skill and the materials are all readily available. A diagram showing what's going on inside a SIP is here. The fundamentals are the same whether you use buckets, tubs, or Earthboxes. Once you make one, it will produce beautiful food for years to come. Many of the photos here are from this second SIP run on the roof, and the pretty yellow pickle buckets are courtesy of Bruce's neighbor who drives for Chicago’s own Vienna Beef (Thanks, Rey! While these instructions are full of details, what you want (a healthy, productive plant) doesn't depend on following them exactly. If you've got hole saws it's far easier to cut the two big holes. View this quick video for a sense of how the whole thing comes together. So now you're ready to make one. This is the fun part. Look what you can grow
Temperature Sensor + Arduino « DanielAndrade.net Hello people, it’s been a while since I have posted projects on this website. This semester was really busy, I didn’t have time to much else, but soon I will have my winter holiday (Here in south our summer holiday is from December to February). Today I am going to show you how to build a simple temperature sensor using one LM35 Precision Temperature Sensor and Arduino, so you can hookup on your future projects. The circuit will send serial information about the temperature so you can use on your computer, change the code as you will. Parts: Arduino (You can use other microcontroller, but then you will need to change the code).LM35 Precision Centigrade Temperature Sensor, you can get from any electronic store. Assembling: This is a quick and simple step. Down goes some pictures that may help you, click to enlarge: Here is the Arduino Code, just upload it and check the Serial Communication Option. You can also download the .pde HERE. Anything just ask!!!
Wired.it-Tutorials/201104_giarduino/README.md at master · mbanzi/Wired.it-Tutorials Did You Win Yet? » Android Garden Monitor Overview One of the coolest things announced at this year’s Google I/O was the Android Open Accessory Kit, which allows Android devices to interact with accessories over USB. As an attendee, I received the Arduino-based ADK DemoKit board, which I’ve used to build an app to monitor my Aerogarden. Hardware Arduino and Breadboard The garden monitor project was built with the following components: Arduino-based Open Accessory KitBreadboardLM34DZ temperature sensorHS1101 humidity sensor0.5″ force sensing resistorAnalog servo The force sensing resistor is mounted below the Aerogarden’s water tank to measure the weight of the water, and the servo is used to open and close the tank door. Software Nexus One running the Garden Monitor app Arduino The Arduino firmware reads the values from the temperature, humidity, and force sensors and sends them to the attached Android device over USB using the Open Accessory protocol.

NEW! How To: V3.0 MAMA w/participatory instructions (beta) We are pleased to announce the V3.0 release of the windowfarms community’s latest windowfarm design, the V3.0, the Modular Airlift Multicolumn Array, or MAMA! quietereasier to set upmore elegant, but still do-able with all recycled water bottlesmore plants for less electrical input (up to 32 plants on one air pump if you do Rama’s double plant mod)modular, meaning you can supply proper nutrients to vegetative, fruiting, and flowering plants all in one system. No more airlift issues with the new tubes. And we have finally achieved some serious height!! Achieving height means you can grow more plants with the same pump so it is way more efficient in terms of the amount of nutritional calories per fossil fuel calorie used in powering the pump. This design described in the free how to is basically the same as the new Classic kit. We decided to release this as a participatory web guide that captures ideas, questions, sketches, discussion, & issues for R&D-I-Y while you build.
