Let me share some green insights about the Automated Hand Rinsing Circuit. This simple but effective project shows how automation can make daily tasks cleaner and more sustainable. By detecting motion and activating a water pump only when needed, it reduces water waste while avoiding direct contact. This makes hand rinsing both hygienic and eco-friendly. Whether it’s for homes, offices, or public spaces, it offers a practical solution for promoting better hygiene with less environmental impact.
The circuit runs on batteries and uses a rocker switch for easy control, helping save energy by turning it off when not in use. It combines a TIP32C transistor with basic electronics to manage the pump efficiently, showing how simple design choices can lower power use and reduce waste. Overall, this project is a great example of how technology can deliver reliable, low-impact solutions that simplify our daily routines.
By building this system, you’re not just creating a helpful device—you’re learning how to design more sustainable and resource-conscious solutions. You’ll gain hands-on experience with assembling, soldering, and wiring, laying a solid foundation for future projects that aim to be both innovative and environmentally friendly. It’s your chance to turn creative ideas into greener real-world solutions!
Components:
For this project, you’ll need an IR sensor to detect motion. A TIP32C transistor to control the water pump, which is connected to an 8mm tube for water flow. The setup includes a white-water pump powered by a 4x AA battery holder, with a rocker switch. To assemble everything, you’ll use jumper wires for the connections, along with a soldering iron and soldering lead. A third hand tool will help hold your parts steady during soldering. A multifunctional wire stripper will make preparing the wires quick and easy. With these tools and components, you’re all set to build your automated circuit.
- IR Sensor
- TIP 32c Transistor
- 8mm Tube
- Water Pump White
- Rock Switch
- Battery Holder 4x
- AA Battery
- Jumper Wires
- Soldering Iron
- Soldering Lead
- Third Hand
- Multifunctional Stripper
Connection:
When the sensor sees an obstacle (like your hand), it sends a signal to a TIP32 transistor that acts as a switch, turning on the pump to dispense water without needing to press anything. A rocker switch is included to manually control power to the system.
