Pi Pico W Soil Monitor with Alerts
Pi Pico W Soil Monitor Kit with Telegram Alerts: Build a Smart Plant Watering Reminder
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Overwatering and underwatering are common plant killers. With this kit, you’ll build a Wi‑Fi connected soil moisture monitor that uses a Raspberry Pi Pico W to measure two pots simultaneously and alert you on Telegram when a plant needs watering. Perfect for home gardeners and school IoT projects.
What You'll Build
A two‑channel soil moisture sensing station with a 0.96‑inch OLED display showing real‑time moisture percentages for both plants. The Pi Pico W posts a message like “Plant 1 needs water!” to a Telegram bot whenever a sensor reading drops below your set threshold, and an active buzzer gives a local audible reminder.
What You'll Learn
- Program a Raspberry Pi Pico W in MicroPython for Wi‑Fi and analog sensor reading.
- Calibrate soil moisture sensors and set custom dry/wet thresholds.
- Create a Telegram bot and integrate HTTP‑based alert notifications.
- Drive an I2C OLED display and an active buzzer from a single microcontroller board.

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part | Pre-tested as a system |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
It fits CBSE Class 11‑12 students tackling IoT practicals or science fairs, B.Tech ECE/EEE students looking for a smart agriculture mini‑project, and participants in Smart India Hackathon exploring agri‑tech. ATL Tinkering Labs will appreciate the ready‑made integration of sensors, display, and alert modules for rapid prototyping.
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?
Our AI companion gives step‑by‑step guidance through every connection and code line, and you can send a WhatsApp message for real‑time human help.
Can I monitor more than two plants?
The included sensors cover two pots, but the Pi Pico W has extra analog pins; you can add more sensors later with minor code changes.
Do I need a Telegram account?
Yes, you’ll create a free Telegram account and a bot. The guide explains the five‑minute setup, and the AI companion walks you through it.
Will this kit work with other microcontrollers?
The sensors and display are compatible with any 3.3V‑logic board, but the code is optimized for the Pico W. Adapting to Arduino or ESP32 is straightforward with minor library adjustments.
Pico W reads soil moisture and posts alert to Telegram bot when plant needs water.
