Plants liven up any space by adding a sense of airiness and life. That is – of course – when you don’t forget to water them, and they shrivel up and die. I am very bad at remembering to water plants. That is why I built this self-watering plant to do it for me. Using a soil sensor, and an Arduino-controlled water pump, I have created a system that will never forget to do it. Instead of remembering to water my plants when the soil goes dry, I only have to remember to once and a while refill the water reservoir. In this way, I have decreased my obligation to these plants and put it off to a much later date. Perhaps further iterations of this device can be connected to a rain barrel so that I won’t even have to worry about refilling my reservoir, and the entire system can be fully automated.

This project is an Electronic Watering Can that provides my plant with water once a week. Sander writes:

To get the necessary carbon dioxide to oxygen conversion Deddies lab is accommodated with a young Ficus Lyrata. To not interrupt its attempt to become the biggest Ficus on earth it needs a weekly dosis of water. That combined with the lab’s motto that everything deserves a microcontroller gave inspiration for a little project on a rainy sunday: An automated electronic watering can!

This project is a plant watering watcher that is able to flash a LED at a low rate when the soil in the pot plant becomes too dry. The circuit uses a CMOS quad Schmitt and is powered from two AA batteries. Check schematic and PCB boards on the link below.

1) IC1D is a CMOS Schmitt trigger oscillator at about 2KHz. It starts and continues to oscillate with a supply down to 1.24V (the lowest output voltage of my LM317 variable power supply) or less.
2) IC1A is an inverter.
3) IC1B is a Schmitt trigger NAND gate. Its output is low only when both inputs are at, or higher than the upper Schmitt trigger threshold voltage.

Here’s a twitter-free version of how to get plants to indicate they need water using about $1.50 in parts, thanks Ben! [via]
