Keep your plants watered with this watering system

If you like growing plants at home, then you know that they are restricted in space and climate. There are some things that you can do and there are that you can’t. You cant control the temperature and light much especially in areas where you live or work. It can be put near the window and temperature is mostly a room temperature. But there is one parameter that can and must be kept in mind – moisture. It is vital to almost any plant to keep soil at some moisture level and this is what you cannot ensure properly unless you keep checking it constantly. So why bother when this work can be done by putting a simple circuit. Frank Donald built a really simple setup that works on Atmega16… Continue reading

Dedicated bot for each plant

Some plants are very sensitive and need constant care. Unless our work is to watch out for plants, we cannot be always there and ensure perfect conditions. So at least for most sensitive we can build a bot that would look after it. Appleman123987 have built good looking planterbot which always keep an eye on plant and displays on LCD when something is needed. Planterbot is based on Arduino Uno which reads plant environment parameters: Thermistor reads surrounding temperature, Cds photocell reads light and moist sensor out of aluminum foil reads water level in soil. The case of planter bot is made of laser cut plywood with cutout for LCD and aluminum moist sensor. No wires are poking out (except USB cable for power). Moist is measured at the bottom.… Continue reading

Self watering plants – do we need them at all?

First of all there is a question. Why would anyone want a plant at home if nobody is gonna even look at it? And if you’re keeping eye how it grows, blooms – poring some water shouldn’t be a problem. Well I see one reason why would you want automatic watering – it is when you leave a house for a longer time. You can say that automatics help keeping soil moist just right what plant needs. No argue with that… So randofo just made an automatic plant watering device based on Arduino. Practically there is nothing unusual in such system. Two metal screws serves as soil moist probes. Arduino takes the reading and activates relay switch once plant needs water. Relay simply turns on non-submersible water pump which delivers… Continue reading

An automated electronic watering can

Growing great and healthy plants it is necessary to take constant care of them. On of concerns include watering. Here it is – an automated electronic watering can that periodically waters the ficus tree. Watering can is equipped with 10 liter bucked which level is monitored with floating duck. If it goes too down, the switch is activated and watering stops. Project is running on AVR Atmega8 microcontroller. As it is based on schedule only this doesn’t mean optimal watering – I’d put a moisture sensor to detect when exactly plant needs to be watered. Despite this this is great project that should help to keep up with plant. Continue reading

Automatic plant watering device

This device may be useful for florists and other who like green environment at home but forget to water them regularly to water them. So why not to automate this process with simple embedded system which controls water pump. Device as design project was developed by student Gang Xie in Stanford University. Device not only waters plant regularly but has a real time clock for exact time counting, LCD which displays time and system states, speaker for alarming, push buttons for changing states and time. Microcontroller controls water pump through relay. Project software is written in AVRGCC C language. Design could be improved by adding humidity of soil reading through ADC channel. Continue reading
