Baby Room Comfort Monitor Kit v8
Build a Long-Range Baby Room Comfort Monitor with ESP32 and LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
As a new parent, the comfort of your infant depends on maintaining an ideal nursery environment — temperature, humidity, and air pressure. This kit gives you the tools to build a long-range LoRa sensor network that monitors these parameters from over a kilometer away, without depending on your home WiFi for transmission. The gateway collects sensor data and uploads it to the cloud, so you can check conditions on your phone from anywhere.
What You'll Build
You'll assemble two battery-powered sensor nodes that stream telemetry via 433MHz LoRa to an ESP32-based gateway. The gateway connects to WiFi and pushes data to a cloud platform (like Blynk or ThingSpeak) for real-time dashboards and alerts. All enclosures are waterproof, suitable for placement in the nursery, even near a humidifier or window.
What You'll Learn
- Assembling an ESP32 LoRa transmitter/receiver pair using SX1278 modules
- Interfacing DHT22 and BMP280 sensors for environmental monitoring
- Managing 18650 battery power with buck converters for field deployment
- Programming cloud connectivity via WiFi and MQTT/HTTP for remote dashboards

Who This Kit Is For
This advanced kit is ideal for engineering graduates, IoT enthusiasts, and parents with electronics experience who refuse to rely on short-range WiFi baby monitors. It's particularly valuable for B.Tech ECE/EEE students designing smart healthcare projects, Smart India Hackathon teams working on rural infant monitoring, and makerspaces focused on assistive technology. If you've tinkered with Arduino or ESP32 and want a reliable, long-range wireless sensor network, this kit delivers a production-grade reference 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 build?
Scan the QR code in the kit to access our AI companion, which provides step-by-step instructions specific to this project. You can also reach us on WhatsApp for direct help from our engineers.
Will the LoRa signal work through walls and floors in a typical Indian home?
Yes, the 433MHz LoRa band penetrates multiple concrete walls easily. In our tests across Bangalore apartments, the signal maintained reliable communication beyond 1km indoors and outdoors.
How do I view the data on my phone?
The ESP32 gateway connects to your home WiFi and can upload data to free cloud platforms like Blynk or ThingSpeak. We provide sample code to set up a dashboard accessible from any smartphone browser.
Can I add more sensor nodes later?
Absolutely. The kit uses a star network topology; you can expand by adding more ESP32+LoRa sensor nodes with the same frequency. The gateway can be programmed to handle multiple nodes.
Infant Care — Two LoRa nodes send sensor data 1km+ range without WiFi. Gateway uploads to cloud via ESP32 WiFi.
