Arduino Plant Monitor Kit with TFT Display
Build an Icon-Based Plant Health Monitor with Arduino Uno and TFT 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.
Keep your leafy friends thriving-without guesswork. This kit lets you build a compact monitor that reads soil moisture, ambient light, and temperature, then shows an intuitive plant health score using happy, neutral, or sad faces on a vivid 1.8-inch TFT colour screen. Whether you are a student exploring IoT or a plant parent tired of overwatering, you will have a functional desk companion in just a few hours.
What You'll Build
You will assemble a real-time health indicator that plugs directly into a plant pot. Insert the soil moisture probe, mount the light and temperature sensors, and watch the TFT display update with colour-coded icons. The monitor sits neatly on a breadboard, ready to help you decide when to water, adjust light, or move a sensitive plant.
What You'll Learn
- Interface analog and digital sensors (soil moisture, DHT22, BH1750) with Arduino Uno
- Use I2C communication to read light intensity and temperature/humidity data
- Drive a 1.8-inch ST7735 TFT display and render custom icons
- Convert raw sensor readings into a meaningful health score using simple thresholds

Who This Kit Is For
CBSE Class 11 and 12 students building sensor-based science fair projects, ATL Tinkering Lab members exploring environmental monitoring, and B.Tech first-year ECE/EEE students looking for a hands-on introduction to data acquisition and display. The build time and documentation suit beginners with some programming familiarity.
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 on the box to open the AI companion; it walks you through each connection and code upload. You can also reach us on WhatsApp for real-time hints.
Can this monitor tell me when to water my plant?
Yes, the soil moisture sensor measures resistance and the Arduino translates it into a dry/moist/wet icon. When the soil becomes too dry, a sad face appears on the TFT, reminding you to water.
Do I have to write all the code from scratch?
Absolutely not. The kit includes pre-written Arduino sketches with libraries for the ST7735, DHT22, and BH1750. The AI companion helps you customise thresholds if you wish.
What if the TFT display doesn't show anything after uploading?
Double-check the SPI pin connections-MISO, MOSI, SCK, CS, and DC-using the wiring diagram in the guide. The AI companion can step you through a quick diagnostic sequence.
