This model demonstrates an automated flood prevention solution using simple sensors and motor mechanisms.
When rainwater is detected, the system activates a submersible pump to drain water from the basement, thus preventing flooding.
This model is especially useful for urban smart homes, low-lying building basements, and monsoon-prone areas.
The project combines basic electronics with environmental sensing, offering a low-cost, practical innovation for real-life problems — aligning with the INSPIRE Award goals of innovation for sustainable development.
When rain is detected (drops fall on the sensor), the system automatically activates the motor pump to drain water from the basement.
This simulates an intelligent solution to prevent basement flooding during heavy rain or storms. The rain sensor mimics detection of incoming water, and the pump mimics real-time drainage.
The entire system is automated and reactive, requiring no human intervention.
Materials Required:
- Rain sensor module (or DIY using aluminum wires and cardboard)
- Water level sensor (optional for flood detection)
- Mini water pump motor (submersible)
- Plastic container or tray (acts as basement)
- Arduino UNO / breadboard (optional: for automation)
- Battery / 9V adapter / USB power bank
- Plastic pipe/tube (to simulate water flow)
- Switch/relay module (to control motor)
- Wires, glue gun, tape, scissors
- Cardboard or acrylic sheet (for housing)
- Transparent pipe (for drainage visibility)
- Small beaker or jug (to pour water and simulate rain)
How to Make It – Step-by-Step:
Step 1: Make the Basement Structure
- Use a plastic container or cardboard box to represent the basement.
- Create an inlet to pour water (simulate rainwater entering the basement).
- Create an outlet hole at the bottom and attach a small pipe.
Step 2: Install the Water Pump
- Place a submersible water pump inside the basement.
- Connect the pipe to the outlet to drain water away (into another container).
- Wire the pump to a switch/relay, connected to power supply.
Step 3: Setup the Rain Sensor
- Fix a rain sensor module (or a DIY version with wires close together on cardboard) at the top of the model to detect falling rainwater.
- Connect the sensor output to a DC Water Pump that turns the pump ON when rain is detected.
