Predictive Washing Machine Cycle Optimizer Kit with ESP32 + LED
Predictive Washing Machine Cycle Optimizer Kit with ESP32 — Stop Unbalanced Spins Before They Start
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 your washing machine knowing the exact moment a load becomes unbalanced, automatically adjusting spin speed before the loud thumping starts. This kit lets you build an ESP32-based current profiler that classifies load balance using an on-device machine learning model, then signals the washer or alerts you via LED — all without modifying the machine’s internals.
What You'll Build
A non-invasive monitoring device that clamps onto your washing machine’s power line, samples current with an ACS712 sensor, and runs a TinyML classifier to detect signature patterns of unbalanced loads. When detected, the system can trigger a relay to adjust spin, log events to microSD with timestamps, and display status on an OLED — giving you a smarter, self‑correcting laundry experience.
What You'll Learn
- Current waveform sampling with ACS712 and ESP32 ADC, including signal conditioning with capacitors and resistors
- Building and deploying a TinyML classification model on ESP32 using Edge Impulse or TensorFlow Lite Micro
- Integrating RTC for time-stamped data logging to microSD, enabling long-term load analysis
- Designing safe isolation and power management for AC appliance monitoring with a buck converter and enclosure

Who This Kit Is For
B.Tech ECE/EEE students prototyping smart energy or home automation projects, hobbyists upgrading their washing machine’s behaviour, and professionals building appliance-level ML. Perfect for Smart India Hackathon teams, IIT/NIT research labs exploring edge AI for domestic appliances, and makerspaces at VIT or BITS looking for a real-world IoT integration challenge.
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 on the box for instant access to the AI companion, or message us on WhatsApp with your order number for engineer-led support within hours.
Can I use this on any washing machine?
The kit is designed for standard 230V AC washing machines common in Indian households. You'll need access to the power cord or internal wiring for non-invasive current sensing. No direct connection to the machine's control board is required.
Do I need prior ML experience?
Basic Python and Arduino IDE familiarity is assumed. The AI companion walks you through training a simple classifier in Edge Impulse — no advanced ML theory required.
What if a component is defective?
All parts are covered by a 7-day replacement warranty. Contact our support team, and we'll ship a replacement from Bengaluru immediately.
