Houseplant Monitor Plus Kit: Arduino Soil Alert & OLED
Houseplant Monitor Plus Kit: Arduino Soil Alert & OLED Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn plant care into a learn-by-doing adventure. Your child assembles a real-time monitor that reads soil moisture with a capacitive sensor, displays the percentage on an OLED screen, and sounds a buzzer when it's time to water. Ideal for young explorers who want to build something that helps at home while picking up core electronics skills.
What You'll Build
A self-contained houseplant monitoring unit. Insert the sensor into the soil, power up the Arduino, and instantly see the moisture level as a percentage on the OLED display. The buzzer activates precisely when the soil drops below the alert threshold, so no more guessing when to water - the plant tells you.
What You'll Learn
- Wiring a soil moisture sensor to an Arduino Uno and reading analog values
- Converting sensor voltage into a percentage display for clear interpretation
- Driving a 0.96-inch OLED screen via I2C communication
- Programming a threshold-based buzzer alert using conditional logic

Who This Kit Is For
Designed for CBSE Class 5-12 students doing school science exhibits and ATL Tinkering Lab explorers discovering sensor basics. Also fits B.Tech ECE/EEE first-year mini-projects and parents seeking a playful weekend STEM activity with tangible results. If you want a project that directly connects code to the real world of plant care, this is it.
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 chat with the AI companion that knows this project inside out - it'll walk you step by step. WhatsApp support is also standing by.
Is the soil sensor capacitive or resistive?
It's capacitive, so there's no exposed metal to corrode over time. You get stable readings season after season.
Do we need coding experience?
Not at all. The AI companion provides ready-to-upload code and explains each line, making it easy even for first-time programmers.
Can we add more sensors later?
Absolutely. The Arduino Uno has spare analog and digital pins. Many builders later add a light sensor or a temperature display, and the AI companion can guide that expansion.
Houseplant - Capacitive soil sensor shows moisture percentage on OLED. Buzzer alerts when plant needs water.
