I love home-grown vegetables. Eat tomatoes straight from the bush and you know how tomatoes have to taste like. I grow my tomatoes in buckets on my balcony and it really works fine. Unfortunately I’m a bit lazy in watering so my harvest was not as good as it could be in the last years.
therefore I decided to make an automatic plant irrigation system. I will use ESP8266 together with temperature/humidity and soil humidity measurements and send the actual values with WLAN to my data central, a Raspberry Pi. The measuring unit should be completely autonomous so they will be quipped with small solar panels each. The Raspberry will be used for data recording and works as controller for the watering unit. For watering I will properly need some pumps because unfortunately I have no chance to make the watering by gravity only.
Last but not least, it should not cost too much!
