Baby Room Comfort Monitor Kit v12
Build a Long-Range Baby Room Comfort Monitor with Pico W, LoRa, GPS and Environmental Sensors
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Keep your infant’s nursery environment perfectly balanced, even from another floor, with a self-built monitor that transmits real-time temperature, humidity, air pressure and precise location over LoRa every 10 seconds. Later, repurpose the same sensor array for high-altitude balloon telemetry—a favourite challenge in B.Tech and Smart India Hackathon projects. This kit merges gentle parent-friendly sensing with hardcore IoT engineering, all on a Raspberry Pi Pico W.
What You'll Build
You’ll assemble a compact sensor node that sits inside a foam enclosure, reading BMP280 for air pressure, DHT22 for humidity and temperature, NEO-6M GPS for geolocation, and transmitting everything on 433MHz LoRa via the RA-02 module. The Pico W handles data collection and forms a unified wireless sensor platform that can be received by another LoRa-equipped Pico or a single-board computer. Whether placed in a baby’s room or launched on a tethered balloon, you get stable, long-range telemetry with no internet dependency.
What You'll Learn
- Interfacing multiple I2C and serial sensors (BMP280, DHT22, NEO-6M GPS) with Pico W in MicroPython
- Constructing a LoRa WAN point-to-point link using RA-02 and 433MHz antenna, including packet formatting and timing
- Implementing low-power battery management with TP4056 and LiPo while sustaining a 10-second transmission cycle
- Designing an isolated foam-encased sensor node that compensates for self-heating and vibration—critical for both nursery deployment and balloon payloads

Who This Kit Is For
B.Tech ECE/EEE students building IoT sensor nodes for Smart India Hackathon or final-year projects will find the LoRa-GPS integration immediately deployable. ATL Tinkering Lab mentors with advanced student groups can use the baby-room angle as a relatable entry point before moving to atmospheric telemetry. Makers from IIT, NIT, VIT or BITS campuses who want a functional nursery monitor and a reusable balloon payload in one build will appreciate the dual-use design.
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 sensor calibration?
The AI companion walks you through BMP280 and DHT22 offsets step by step, and you can reach our WhatsApp support team with photos of your wiring if something still doesn't match.
Can this really monitor a baby's room from another floor without Wi-Fi?
Yes. LoRa on 433MHz easily penetrates concrete floors and walls. In typical Indian apartment constructions you can expect reliable reception up to 100 metres indoors, and the AI companion helps you optimise antenna placement.
How do I switch between nursery monitoring and balloon telemetry?
Same hardware—just change the firmware logic. The AI companion provides separate MicroPython scripts for indoor fixed-location monitoring and outdoor balloon flight modes with different transmission intervals and GPS parsing.
Does the kit require an LoRa receiver on the other end?
Yes, you'll need a second Pico W with another RA-02 or a single-board computer with a LoRa hat to receive and display the data. The kit includes the transmitter node, and the companion guide shows how to set up a simple receiver with your own spare Pico.
Infant Care — Pico W reads BMP280 + DHT22 + GPS and transmits telemetry over LoRa every 10 seconds during balloon flight.
