Abstract

The article covers the development of an automated solar-powered plant watering system that will help home gardeners who struggle with locating sufficient time to irrigate their plants. The system monitors the surrounding plantation and the state of the soil beneath the plants using DHT11 humidity temperature sensors and soil moisture sensors. Utilising the Arduino IDE programme, the Arduino Uno R3 (Atmega 328p) receives the readings from these sensors to determine the state of the plant. In order to determine if the plant is receiving enough water and to regulate the water pump to irrigate it, the Arduino IDE programme computes the sensor values and determines whether the soil condition is above or below the threshold value. For the automated plant watering system to function, a five-volt solar panel and an MPPT charging controller are required. The DHT11 Sensor and Soil Moisture Sensor recommended ranges are clearly stated and documented in the article.
