Water scarcity is a pressing global issue, and rainwater harvesting presents a sustainable solution to conserve and utilize natural water resources. The Arduino-Controlled Rain Harvesting Unit is a smart automation system that detects rainfall and manages the diversion and storage of rainwater efficiently. This system automates traditional rainwater harvesting using electronic sensors and a microcontroller, ensuring optimal water collection without human intervention.
The use of an Arduino Uno as the core controller, paired with sensors such as a rain sensor and water level sensor, allows the system to detect rainfall, initiate water diversion to tanks, and monitor the tank’s water levels in real time. This reduces overflow, enables controlled usage, and maximizes the utility of harvested rainwater for domestic or agricultural purposes.
The Arduino-controlled system functions by sensing rain and automatically managing water flow and storage as follows:
A rain sensor detects the presence and intensity of rainfall.
When rain is detected, the Arduino Uno activates a mechanism (e.g., a solenoid valve or relay-controlled motor) to divert rainwater into a storage tank.
A water level sensor monitors the level inside the storage tank and sends real-time data to the Arduino.
If the water tank reaches full capacity, the Arduino stops the water intake to prevent overflow by closing the valve or motor.
The system resets automatically and waits for the next rainfall event, ensuring sustainable and efficient rainwater collection.
The implementation steps of the Arduino-Controlled Rain Harvesting Unit are as follows:
A rain sensor module is mounted outdoors to detect rainfall.
The sensor outputs digital/analog signals based on wetness, which the Arduino reads.
The Arduino continuously monitors sensor inputs.
When rain is detected, the Arduino sends a control signal to activate a motor or valve to start collecting rainwater.
A water level sensor placed inside the storage tank checks the level of water.
If the water reaches the maximum threshold, the Arduino stops the water inflow to prevent spillage.
The logic runs continuously in a loop, automating the entire harvesting process without manual input.
