Watering flowers and plants is a time-consuming – and repetitive task. So the idea was born to help the gardener by taking the daily manual work off his hands, developing an automated plant watering device.
The central processor consists of a Micro:bit and an additional card connected to sensors for humidity, temperature, light and rain. The second processor – also a Micro:bit – is connected to the pump that controls the whole system.
The first processor measures the humidity in the soil, the temperature, the light and the rain and transmits the signal to the Lora card to automatically turn the pump on and off. When the pump is running, it sends the signal to the other processor to control the watering of the plants in the specified order and duration.
