Pi Pico W Gas Alert Notifier
Build an IoT Gas Leak Alert System with Raspberry Pi Pico W – Push Notifications to Your Phone
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Kitchen gas leaks are a serious safety concern. With this kit, you’ll build a Wi-Fi-connected device that sniffs out combustible gases like LPG and methane, then instantly pings your phone with an alert—even if you’re miles away. It’s the perfect hands-on project for learning IoT, sensor integration, and remote notification systems.
What You'll Build
You’ll assemble and program a standalone IoT gas alarm on a breadboard. The Raspberry Pi Pico W reads the MQ-2 sensor, triggers a buzzer and two LEDs locally, and sends an HTTP push notification to your phone via a service like Pushover or IFTTT. After a few hours, you’ll have a fully functional gas alert station ready to place in your kitchen, lab, or workshop.
What You'll Learn
- How to interface an analog gas sensor with a microcontroller using ADC
- Configuring HTTP POST requests on the Pico W to send push notifications
- Setting threshold-based triggers in MicroPython for real-world sensing
- Building a prototype safety device on a breadboard and planning for permanent deployment

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part (voltage dividers, ADC ranges) | Pre-tested as a system—MQ-2 works with Pico W’s ADC out of the box |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project—guides every connection and line of code |
| Time to first working build | Days of debugging Wi-Fi, HTTP, and sensor quirks | Hours, with step-by-step guidance on push notification setup |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
This kit is ideal for CBSE Class 11-12 students exploring IoT in their informatics or electronics curriculum, B.Tech ECE/EEE undergraduates working on smart home projects for Smart India Hackathon, and ATL Tinkering Lab mentors guiding safety innovation. It’s also perfect for makers who want a reliable gas alert without coding the Wi-Fi stack from scratch.
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?
Just scan the QR code on the box or ping us on WhatsApp. The AI companion will walk you through the exact step you’re on, and you can always escalate to a human if needed.
Do I need a push notification service account?
Yes, you’ll set up a free account with Pushover or IFTTT Webhooks; the AI companion provides direct links and a walkthrough for registering and obtaining API keys.
Can this detect LPG and smoke?
Absolutely. The MQ-2 is sensitive to LPG, methane, butane, and smoke—making it perfect for kitchen gas leak detection and early fire warning in your prototype.
Is the kit safe to use in a real kitchen?
As a prototype, it’s safe for testing and learning purposes. For permanent deployment, you’ll need an appropriate enclosure and a reliable power supply, which are easy next steps covered by the AI companion.
MQ-2 gas sensor triggers Pico W to send HTTP push notification to phone when gas exceeds threshold.
