Pi Zero W MQTT Home Sensor Hub Kit with Raspberry Pi Zero + DHT22
Build Your Own MQTT Home Sensor Hub with Raspberry Pi Zero W and DHT22
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 small device in your room that broadcasts temperature, humidity, and motion alerts to any screen on your home network. This kit hands you exactly that — a Raspberry Pi Zero W transformed into a local MQTT broker publishing DHT22 and PIR sensor readings every 30 seconds. It's a practical intro to wireless sensor networks, ready for CBSE projects, hackathons, or your first smart home corner.
What You'll Build
A compact sensor station that streams real-time environment data. The DHT22 captures air temperature and humidity, while the HC-SR501 watches for movement. All readings are published as MQTT topics you can subscribe to from a laptop, phone, or custom dashboard. No cloud dependency — everything runs on the Pi itself.
What You'll Learn
- Set up and configure a Mosquitto MQTT broker on Raspberry Pi OS
- Interface DHT22 and HC-SR501 sensors with GPIO pins
- Write Python scripts to publish sensor data in structured JSON format
- Design a periodic sensor polling loop that runs every 30 seconds

Who This Kit Is For
If you're a Class 11 or 12 CBSE student building an IoT science exhibit, a first-year B.Tech ECE undergrad exploring sensor networks, or a Smart India Hackathon participant who needs a reliable sensor node without chasing components, this kit is your shortcut. ATL Tinkering Labs and engineering colleges like IIT, NIT, VIT, and BITS regularly use our kits for their hands-on sessions.
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 to start a conversation with the AI companion trained on this kit; it walks you through each wiring and code step. You can also reach us on WhatsApp for direct help.
Do I need soldering for this kit?
The Raspberry Pi Zero W ships without a pre-attached GPIO header. You will need basic soldering to attach the included 40-pin header. If you prefer a solder-free option, hammer headers (not included) can be used.
Can I view sensor data on my phone?
Yes, once the MQTT broker is running, install any MQTT client app on your phone (like MQTT Dash or IoT MQTT Panel), connect to the Pi’s IP address, and subscribe to the topic to see live temperature, humidity, and motion alerts.
What power source do I need?
The kit includes a micro USB cable; you can power the Pi Zero W from any standard USB power adapter or portable power bank (not included). A 5V/2A supply is recommended for stable operation.
Pi Zero W runs Mosquitto MQTT broker. DHT22 and PIR data published every 30 seconds from GPIO.
