Baby Room Comfort Monitor Kit v10
Baby Room Comfort Monitor Kit v10 — Build a Python & Arduino-Powered Nursery Monitoring System
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 a peace of mind that comes from knowing your baby's nursery environment is perfectly controlled. This kit lets you build a real-time comfort monitor that logs temperature, humidity, and barometric pressure to a time-series database, while an embedded microcontroller automatically adjusts fans or heaters based on preset thresholds. You'll combine Python on Linux for data logging and visualisation with Arduino-based relay and PWM control — a true IoT project from sensor to actuator.
What You'll Build
You'll assemble a compact device that continuously reads DHT22 and BMP280 sensors, displays readings on a 0.96-inch OLED, and writes every data point to InfluxDB on your Linux machine. The Arduino UNO Q microcontroller runs a real-time control loop: if temperature rises too high, it triggers a relay to switch on a fan; if humidity drops, it activates a humidifier via another channel. PWM control dims an LED nightlight as per comfort thresholds. The data is accessible from any phone or laptop via Grafana dashboards, helping you keep a close eye on the nursery even when you're not in the room.
What You'll Learn
- Integrating DHT22 and BMP280 sensors on I2C and one-wire buses with an Arduino-compatible STM32-based board
- Designing real-time relay and PWM actuator logic in Arduino C++ for fan, heater, and light control
- Writing a Python script on Linux to fetch serial data and push to InfluxDB for time-series storage
- Setting up Grafana dashboards to visualise temperature, humidity, and pressure trends

Who This Kit Is For
Designed for B.Tech ECE and EEE students exploring IoT, this kit fits perfectly into Smart India Hackathon prototypes, final-year projects at IIT/NIT/VIT/BITS, and anyone building a safety-automation portfolio. If you're comfortable with basic Arduino programming and want to bridge sensors, databases, and real-time control on a single Linux machine, you're ready for this build.
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 your enclosure box to open the AI companion. It knows every step, from wiring the BME280 to configuring InfluxDB. For human help, our WhatsApp support responds within an hour.
Can I monitor the nursery data on my phone?
Yes. InfluxDB data can be queried by Grafana, which renders mobile-friendly dashboards you can open from your phone's browser while on the home Wi-Fi network.
Is the Linux machine included?
The kit does not include a single-board Linux computer. You can use any existing Ubuntu laptop, a Raspberry Pi, or an old PC running Linux. We provide a full setup guide for Debian-based systems.
What can the relay and PWM control exactly?
The 4-channel relay switches low-power AC appliances like a table fan, humidifier, or small heating pad. PWM output drives a dimmable LED strip or nightlight connected to a simple transistor driver (not included). The enclosure has knockouts for safe wiring.
Infant Care — Python on Linux logs DHT22 + BMP280 to InfluxDB. Arduino sketch on STM32 handles relay and PWM in real time.
