Water Tank Level Monitor Mini Kit with Arduino Uno + Ultrasonic
Water Tank Level Monitor Mini Kit: Automate Your Aquarium Top‑Ups with Arduino Uno & HC‑SR04
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
No more manual top‑ups that stress your fish. This kit turns an Arduino Uno and an ultrasonic sensor into an automated water refill system for your aquarium. Whenever evaporation drops the water level below your set threshold, a silent submersible pump kicks in to restore it — all while you’re away from home.
What You'll Build
You’ll wire up an HC‑SR04 ultrasonic distance sensor to measure water level, calibrate it for your tank’s height, and program the Arduino to trigger a 5V relay module that switches on a mini pump. The end result is a hands‑free top‑up system that keeps your aquarium stable and your fish healthy.
What You'll Learn
- Interfacing an HC‑SR04 ultrasonic sensor with Arduino and reading distance values
- Writing logic in Arduino IDE to automate actions based on real‑time sensor data
- Controlling a high‑power device (pump) safely using a relay and flyback diodes
- Building a practical smart monitoring solution that solves a real household problem
