Automatic Plant Watering System Using Arduino Automatic Plant Watering System Using Arduino This project creates a smart automatic plant watering system that monitors soil moisture and waters plants only when needed. Using Arduino, a soil moisture sensor, and a water pump, this system ensures your plants get the perfect amount of water while conserving resources. How the System Works Soil Moisture Sensor continuously monitors the soil's moisture level Arduino UNO processes sensor data and controls the watering system Relay Module acts as a switch to control the water pump safely Water Pump turns ON when soil is dry and OFF when soil is sufficiently moist Li-ion Battery provides portable power for standalone operation Smart Logic: System checks soil moisture every 2 seconds and waters for 3 seconds when needed Water Conser...
