Automatic Pet Water Refill Kit with Arduino Uno + Sensor
Automatic Pet Water Refill Kit with Arduino Uno – Never Let Your Pet’s Bowl Run Dry Again
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Fresh water for your pet shouldn’t depend on your schedule. This kit lets you build a fully automatic refill station that senses when the bowl is low and pumps water from an overhead reservoir — no manual topping up, no dry bowls. Whether you’re a young maker exploring smart home gadgets or a pet parent looking for a reliable solution while you’re away, you’ll create a system that works 24/7 on Arduino logic.
What You'll Build
By the end of a single afternoon, you’ll have a breadboarded control circuit with a float sensor monitoring water level and a submersible pump that turns on exactly when needed. Place the sensor in your pet’s bowl, connect the silicone tube from the pump to a bottle or bucket placed above the bowl, and the Arduino takes over — when the float drops, the relay clicks and water flows until the level is safe again. It’s a tangible lesson in home automation that you can actually use every day.
What You'll Learn
- Interface a float sensor with Arduino and read high/low digital states accurately
- Control a 5V relay module to switch a pump without damaging the microcontroller
- Use 1N4007 diodes and resistors to protect circuits from voltage spikes and current surges
- Write and upload code that reacts to real‑time sensor data for reliable water refill logic

Who This Kit Is For
Young innovators (ages 10+) who want to build something practical for their home, school students in ATL Tinkering Labs, and CBSE Class 6–10 learners exploring automation will thrive with this kit. It’s also a great choice for B.Tech ECE first‑semester students doing hobby projects, and for pet owners who enjoy DIY solutions. No prior coding experience? The AI companion walks you through every line.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code inside the box to chat with the AI companion trained on the exact water refill project. It can answer circuit questions, explain code logic, and troubleshoot step by step. WhatsApp backup is also available for tricky issues.
Can this work for a bird or small animal?
Absolutely. The float sensor is small and works in any water bowl sized for tiny pets. Just make sure the bowl is stable and the sensor isn’t blocked by the animal. You may need to adjust the trigger height slightly in the code.
Do I need an external water container?
Yes, you’ll need a clean overhead reservoir — a plastic bottle, bucket, or jar placed above the bowl. The kit includes the pump and silicone tubing; you provide the water source. Gravity helps the flow once the pump starts.
Is any soldering required?
No soldering at all. All connections go into the included 400‑point breadboard using jumper wires. Just push components in place, plug in the Arduino, and your circuit is ready — perfect for beginners and repeatable experiments.
Float sensor on pet bowl triggers relay pump when low. Auto-refills from overhead reservoir.
