Smart Watering Plant is an automated system designed to water plants efficiently using a microcontroller like Micro:bit. It uses a soil moisture sensor to detect the dryness level of the soil. When the soil is too dry, the sensor sends a signal through jumper wires to the Micro:bit, which then activates a relay. The relay turns on a DC pump to supply water to the plant. This system helps maintain proper soil moisture and reduces the need for manual watering.
