Baby Room Comfort Monitor Kit: Dryer Pause Automation 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.

Babies have sensitive skin, and clothes that are over-dried can become rough or static, while damp clothes never feel ready. This kit lets you build a smart monitor that automatically pauses your dryer when the humidity inside the drum drops below 30%—the sweet spot where fabrics are dry but still soft. No more second-guessing the timer or checking the laundry mid-bath. It’s a simple automation that makes infant care one step gentler.

What You'll Build

You’ll assemble a compact circuit that reads humidity from a DHT11 sensor placed safely inside the dryer drum. When the Arduino detects that the humidity has fallen below a set threshold, it triggers a relay module to pause the tumbler motor. A simple LED indicator shows the system status, and the entire setup is powered by a 9V battery. The result is a clothes dryer that stops exactly when your baby’s clothes are perfectly dry, saving energy and preserving fabric softness.

What You'll Learn

• How to read real-time humidity data from a DHT11 sensor using Arduino Uno
• How to control a high-power appliance safely through a 5V relay module
• How to write conditional logic in Arduino IDE to automate decisions based on sensor values
• How to build circuits on a breadboard, including using protection diodes and pull-up resistors

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This beginner-friendly project is perfect for school students (Class 5–10) who want to submit an electronics project at a science fair or ATL Tinkering Lab. It also makes an ideal parent-child activity for families introducing automation at home. Even first-year B.Tech ECE/EEE students can use it to understand sensor-actuator loops in a real-world infant care scenario. No prior soldering or coding experience is needed—the AI companion walks through every line of code.

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.
