Indoor Houseplant Monitor Kit with Arduino Uno + DHT22
Master Smart Farming with a Self-Regulating Houseplant Monitor Using Arduino Uno & DHT22
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine your prized orchids or delicate kitchen herbs monitored continuously, with ventilation and alerts triggered automatically when conditions drift. This kit lets you build a multi-sensor environmental station that reads temperature, humidity, soil moisture, and atmospheric pressure, then uses dual servos to open or close climate vents and a buzzer to sound warnings—while all data logs to a microSD card with a timestamp. Whether you are a B.Tech student crafting a smart agriculture mini‑project or a hobbyist wanting to automate a small greenhouse, this kit turns the lens of precision farming onto a single houseplant.
What You'll Build
A fully integrated plant care system. Two soil moisture probes monitor separate root zones, the DHT22 captures ambient temperature and humidity, and the BMP280 records barometric pressure to spot weather trends. When readings cross thresholds you define, the SG90 servos physically adjust two ventilation flaps, the active buzzer sounds a local alarm, and every sensor value is written to a microSD card with a real‑time DS3231 timestamp. The 16×2 LCD with I2C backpack displays live data and system status, so you can glance and know the plant’s wellbeing without a computer.
What You'll Learn
- Multi‑sensor fusion: reading DHT22, BMP280, and analog soil moisture sensors via Arduino with proper pull‑up and filtering.
- Real‑time clock integration with the DS3231 to timestamp every log entry on the SD card.
- Servo motor control for physical actuation—translating sensor thresholds into precise vent opening angles.
- Designing a modular monitoring board on PCB prototype boards, moving from breadboard to a rugged, repeatable layout.

Who This Kit Is For
This advanced project is built for B.Tech ECE, EEE, and agricultural engineering students who need a hardware‑heavy mini‑project or a Smart India Hackathon prototype. It also fits ATL Tinkering Labs that have progressed beyond basic sensors, and final‑year learners at IIT, NIT, or VIT who want to demonstrate closed‑loop environmental control. If you have prior Arduino exposure and want to move from simple sensor readings to a deployed, logging automation system, this kit gives you a full‑stack smart farming testbed.
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 talk to the AI companion that knows this kit’s wiring, code, and troubleshooting. If you need human help, our WhatsApp support team replies within an hour with personalised guidance.
Can I log data to a PC instead of an SD card?
Yes, the Arduino serial monitor outputs live readings, but the included MicroSD module lets you store days of standalone data—perfect for long‑term plant behaviour analysis.
Does the kit include an actual fan and water pump?
The servos directly drive small ventilation flaps; for heavier loads like pumps or fans, the kit provides output pins and prototype space to build relay driver circuits. External relay modules are not included, but the system architecture is designed for easy expansion.
Is the code open‑source and modifiable?
Absolutely. You receive full Arduino source code with detailed comments. You can tweak sensor thresholds, add an ESP8266 for IoT data upload, or integrate additional sensors—the entire project is yours to extend.
Houseplant — DHT22 + soil moisture trigger servo vent, relay fan, relay pump to maintain target conditions. Logs to SD.
