Bluetooth Sensor Monitor Kit - Arduino Uno HC-05 Wireless Project
Bluetooth Sensor Monitor Kit: Send Temperature & Humidity Data to Your Phone with Arduino Uno & HC-05
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 checking your room's temperature and humidity from your phone without any wires-this kit makes it happen. You'll assemble an Arduino Uno with an HC-05 Bluetooth module and a precision DHT22 sensor, then watch live readings stream directly to the Serial Bluetooth Terminal app every two seconds. Perfect for science experiments, home automation trials, and learning the basics of Bluetooth communication.
What You'll Build
A portable wireless sensor station that continuously transmits temperature and humidity data to any Android phone. Place the sensor in a plant pot, an incubator, or your study desk and monitor conditions from across the room. The system runs on a 9V battery, so you can take it anywhere for field experiments.
What You'll Learn
- How to wire a DHT22 sensor and read digital data with Arduino
- Setting up serial communication over Bluetooth using the HC-05 module
- Parsing real-time sensor data for display on a phone app
- Basic power management for standalone battery operation

Who This Kit Is For
This kit is designed for absolute beginners-whether you're a young maker (ages 5+) building with a parent, a CBSE Class 11-12 student preparing a physics practical, a B.Tech ECE/EEE fresher exploring wireless sensor networks, or an ATL Tinkering Lab innovator prototyping for Smart India Hackathon. It works right out of the box, so anyone curious about IoT can succeed.
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 the box to open the AI build companion-it's trained on this exact kit and answers your questions instantly. You can also reach us on WhatsApp for personalized help.
Is any soldering or coding experience required?
No soldering is needed; the breadboard makes all connections plug-and-play. The Arduino code is provided, and you can simply upload it-no prior coding experience is necessary.
Can I use the kit with an iPhone?
The HC-05 Bluetooth module works with Android devices by default. For iOS, you can use a BLE-compatible module or adapt the project; the kit is best suited for Android phones running the Serial Bluetooth Terminal app.
What if my phone doesn't detect the HC-05 module?
Ensure the module is correctly wired, the Arduino is powered, and your phone's Bluetooth is on. The AI companion and our WhatsApp support can guide you through pairing step-by-step.
HC-05 sends DHT22 readings to Serial Bluetooth Terminal app on phone every 2 seconds.
