Baby Room Comfort Monitor Lab with FreeRTOS & MQTT — ESP32 IoT Kit

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 an electronics kit that transforms a handful of sensors and an ESP32 into a real-time infant room monitor — all while teaching you the professional embedded design pattern of task scheduling and cloud connectivity. This lab kit puts you at the centre of a use case that matters to every parent: maintaining a safe sleep environment. You’ll wire two DHT22 sensors, a BMP280 pressure chip, and an OLED display to an ESP32, then write firmware that reads environmental data inside a FreeRTOS producer task, queues it safely, and pushes MQTT messages from a consumer task. That’s the backbone of responsive, non‑blocking IoT devices.

What You'll Build

By the end of 3–4 hours, you’ll have a functioning baby room monitor that displays live temperature and humidity on its OLED screen and publishes data to an MQTT broker like Mosquitto. The two‑task architecture means you can swap sensors or dashboard apps without breaking the core logic — exactly how field‑ready firmware is written. Your monitor will flag subtle changes in room climate, giving you a hands‑on understanding of why synchronized, threaded code matters in safety‑critical applications.

What You'll Learn

• Create and synchronize FreeRTOS tasks on the ESP32 to read DHT22 and BMP280 sensors concurrently without blocking
• Implement a producer‑consumer data pipeline using FreeRTOS queues, ensuring sensor values travel cleanly between tasks
• Configure MQTT publishing via Wi‑Fi so temperature, humidity, and pressure appear in real‑time dashboards or phone apps
• Interface multiple I2C peripherals — OLED, BMP280 — on the same bus while managing address conflicts and power stability

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students diving into embedded systems for the first time will find the RTOS concepts laid out neatly, while B.Tech ECE/EEE second‑year learners can use this as a mini‑project that demonstrates real multitasking. If you’re preparing for the Smart India Hackathon or need a polished ATL Tinkering Lab exhibit, the infant‑monitor use case is both relevant and socially impactful. Even IIT/NIT/VIT/BITS students building a portfolio for IoT or FreeRTOS roles will appreciate a ready‑to‑fork foundation that’s documented inside the AI companion.

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.
