Build an Automatic Laundry Detergent Level Monitor with Arduino Uno

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine never running out of detergent mid-cycle again. This kit lets you build a smart sensor that sits inside the detergent drum, precisely measuring the remaining level using ultrasonic sound waves. When the level dips below 20%, the OLED display flashes a warning and an active buzzer sounds—so you’re always ready for the next load.

What You'll Build

A compact, wall-mountable monitor with a clear OLED percentage readout and an audible alert. The sensor module fits into the detergent drum lid, continuously gauging distance to the powder surface, and recalibrates automatically when you refill. You’ll own a practical home automation device that saves time and eliminates guesswork.

What You'll Learn

• Interface an HC-SR04 ultrasonic sensor with Arduino Uno for non-contact distance measurement.
• Display real-time data on a 0.96-inch OLED using I2C communication.
• Implement threshold-based alerts using an active buzzer and conditional logic.
• Calibrate sensor readings for a specific container shape and powder level.
