Baby Room Comfort Monitor Kit v17
LoRa Baby Room Monitor Kit – Solar Node for Air Quality, Temp & Humidity
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Every parent glances at the baby monitor screen a little more often than they admit. With this kit, you build a self-contained sensor node that reads room air quality (MQ-135), temperature and humidity (DHT22), and atmospheric pressure (BMP280), then transmits the data packet over a 433MHz LoRa link to a receiver every 5 minutes. The node is solar-powered, so it runs day and night without a battery swap, making it a practical infant care tool, not just a lab experiment.
What You'll Build
You construct a weatherproof sensor enclosure that mounts near the cot or changing table. The node sleeps between readings, wakes every 300 seconds, collects three environmental data points, and sends them via LoRa to any Arduino-based receiver you set up at your desk. The solar panel charges dual 18650 cells through a TP4056 module, so the unit stays up indefinitely even during monsoon stretches under indoor light.
What You'll Learn
- Interfacing multiple I2C and analog sensors on a single Arduino Nano without bus conflicts
- Configuring the RA-02 LoRa module for 433MHz transmission with low-power sleep modes
- Designing a solar battery management circuit with TP4056 and 18650 cells for a 6V 2W panel
- Writing timer-based wake-up logic that transmits structured sensor packets every 5 minutes

Who This Kit Is For
Students in CBSE Class 12 or B.Tech ECE/EEE who need a working IoT project for board practicals or Smart India Hackathon demos will find the sensor fusion and power-management logic directly applicable. ATL Tinkering Lab instructors can use the kit to teach LoRa mesh concepts, and parents with a maker bent can build a reliable nursery monitor that doesn't depend on Wi-Fi.
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 in the box for the AI companion that has been trained on this exact circuit and LoRa packet structure. For direct human backup, reach out via WhatsApp and we'll walk you through the issue.
How far can the LoRa signal reach indoors?
With the included 433MHz antenna, you can expect solid reception through two concrete walls and across a typical Indian home (30–50 metres). Outdoor line-of-sight can exceed 500 metres.
Does the solar panel keep the node running at night?
Yes. The 6V 2W panel charges the two 18650 cells during the day, and the node's 5-minute sleep cycle draws so little current that the batteries easily power the unit through the night and cloudy days.
Can I view the sensor data on my phone?
The kit transmits to any LoRa receiver you pair it with. Most makers add a second Arduino with an ESP8266 to push readings to a Blynk dashboard or a simple web server for phone notifications.
Infant Care — MQ-135, DHT22 and BMP280 readings packaged and transmitted via RA-02 LoRa every 5 minutes from solar node.
