Pi Pico W Alarm Notifier
Raspberry Pi Pico W Alarm Notifier Kit – Instant Telegram Alerts When Gas or Motion Is Detected
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Worry less about gas leaks or unexpected motion when you're away from home. With this kit, you’ll build a compact Raspberry Pi Pico W device that watches over your space using a PIR motion sensor and an MQ-2 gas sensor. If either sensor trips, the Pico W instantly sends a Telegram notification to your phone, so you can take action no matter where you are.
What You’ll Build
A standalone, battery-powered notifier that sits in any room. The Pico W connects to Wi‑Fi and continuously monitors its surroundings. When the PIR detects movement or the MQ-2 senses combustible gas (like LPG or smoke), the active buzzer sounds locally, and within seconds, a detailed alert hits your Telegram chat—including which sensor triggered and a timestamp. The ABS enclosure holds everything neatly, making it ready to deploy in a kitchen, garage, or dorm room.
What You’ll Learn
- Connecting a PIR motion sensor and an MQ-2 gas sensor to a microcontroller’s GPIO pins
- Writing MicroPython scripts that read sensor states and trigger actions
- Creating a Telegram bot and using its HTTP API to send rich notification messages
- Enclosing a working prototype into a finished, deployable hardware product

Who This Kit Is For
This kit is ideal for CBSE students taking their first steps into IoT, ATL Tinkering Lab participants wanting a sensor-based project, and curious minds aged 10–15 who want to build a device that alerts family members on their phones. Under parent guidance, even 5–9 year olds can assemble the enclosure and watch the sensors work.
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 inside the box to launch your AI companion, which has been trained on every step of this exact project. If you still need help, we’re available on WhatsApp for direct guidance.
Do I need to solder anything?
No soldering required; all components connect using the included M-M jumper wires and the Pico W’s breadboard-friendly pins. You can build the entire circuit on a breadboard (not included) or simply place it in the enclosure with jumper wires.
Can I monitor from outside my home Wi‑Fi network?
Yes. As long as the Pico W stays connected to a Wi‑Fi network with internet access, Telegram notifications reach your phone anywhere in the world. The bot uses Telegram’s cloud API, so no router configuration or port forwarding is needed.
Can I add more sensors later?
Absolutely. The Pico W has spare GPIO pins, and the AI companion can guide you on extending the code and connections. Common add‑ons include a temperature sensor, a door switch, or even a camera module for visual verification.
Pico W reads PIR and gas sensor. Sends Telegram notification if alarm triggers while away from home.
