EcoDuino Automatic Plant Cultivation Kit

EcoDuino from DFRobot is a kit for automatic watering of potted plants. The control board with ATmega32U4 is programmed like an Arduino Leonardo via Micro USB. A soil moisture sensor measures the moisture of the soil, a DHT11 the temperature and humidity. When the soil moisture falls below the threshold set with the potentiometer, the submersible pump waters. The enclosure is protected against splashing water, and power comes from 6 to 12 V or the 6 × AA battery holder. Batteries are not included.

Recommended Accessories:

• 9V DC 5000mA Power Supply AC/DC Adapter 5.5mm/2.1mm Plug
