Baby Room Comfort Monitor Kit with Arduino Uno + LED
Baby Room Comfort Monitor Kit with Arduino Uno & OLED: Build a Reusable Menu System with Rotary Encoder
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wished you could check your baby’s room comfort without a smartphone app? This kit lets you build a standalone monitor that reads temperature, humidity, and controls an appliance through a sleek OLED menu—navigated entirely with a rotary encoder. The real gem: a reusable UI code structure you can drop into any future Arduino project, saving hours of firmware design each time you need a polished on-device interface.
What You'll Build
You'll assemble a compact sensor unit that displays real-time temperature and humidity from a DHT22 on a crisp 0.96-inch OLED, with a multi-level menu that responds to long and short presses of a rotary encoder. A relay output lets you automatically switch a fan or heater based on comfort thresholds you set right from the menu. All wrapped in a clean, extensible codebase that handles debouncing, state machines, and screen transitions.
What You'll Learn
- Designing a responsive rotary encoder menu system with debouncing and multi-level state machines
- Interfacing DHT22 for precision temperature and humidity sensing
- Driving a 0.96-inch OLED display via I2C to show live data and menu screens
- Controlling a 5V relay to automate appliances based on sensor thresholds

Who This Kit Is For
This kit is designed for B.Tech ECE/EEE students building mini or major projects, Smart India Hackathon participants prototyping healthcare or home-automation solutions, and tech-savvy parents who want a custom baby monitor with fully reusable interface code. It assumes basic Arduino programming experience, making it a natural fit for final-year engineering labs, ATL tinkering clubs at college level, and individual makers who want to master embedded menu systems.
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 access the AI companion trained on this exact project. It diagnoses wiring and code issues step by step. For persistent problems, reach us on WhatsApp and a human will jump in.
Can I use the menu system in other projects?
Absolutely. The rotary encoder UI code is structured as a reusable module—just copy the files and tweak the menu items. It's the same approach we teach in our advanced Arduino workshops.
Is the soldering iron suitable for fine PCB work?
Yes, the included 25W soldering iron has a conical tip perfect for joining components on the prototype board. We've chosen it specifically for this kit's soldering joints, and the solder wire is lead-free.
Does this kit include a case or enclosure?
The kit focuses on the core electronics; you can place the assembled board in a ventilated box of your choice. We provide mounting holes on the PCB prototype board for secure installation.
Infant Care — Rotary encoder navigates multi-level OLED menu. Long press enters, short press scrolls. Reusable UI code.
