Indoor Houseplant Monitor Kit with Arduino Mega + DHT22
Indoor Houseplant Monitor Kit: Log Every Environmental Factor with Arduino Mega + 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.
Monitor the health of your houseplants like a scientist. This Arduino Mega‑based kit tracks temperature, humidity, light intensity, and soil moisture, logging it all to a microSD card with precise timestamps. Ideal for CBSE Class 11‑12 biology projects, B.Tech mini‑projects, or Smart India Hackathon prototypes.
What You'll Build
A complete indoor environmental monitoring station that reads dual DHT22 temperature/humidity sensors (for comparison), BMP280 barometric pressure, BH1750 ambient light, and two soil moisture probes. Data is displayed live on an OLED screen and saved with DS3231 real‑time clock stamps to a microSD card, giving you a CSV file ready for analysis in Excel or Python. Perfect for studying how microclimate varies across a plant shelf or room.
What You'll Learn
- Connect multiple I2C and analog sensors to an Arduino Mega
- Read and calibrate soil moisture sensors for accurate plant data
- Log timestamped sensor data to a microSD card using a DS3231 RTC
- Visualize real‑time readings on an OLED display

Who This Kit Is For
Designed for intermediate makers — CBSE Class 11‑12 students working on biology or computer science investigatory projects, B.Tech ECE/EEE students building mini‑projects, and participants in Smart India Hackathon prototyping plant health monitors. It also fits ATL Tinkering Labs teaching sensor integration and data logging, and is a favourite among hobbyists at IIT/NIT/VIT B.Tech clubs.
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 access your AI build companion; it's trained on this exact project. You can also reach us on WhatsApp for personalized support from our team.
Can I monitor more than two plants with this kit?
The kit includes two DHT22 and two soil moisture sensors, but you can add more sensors using the spare digital and analog pins on the Arduino Mega. The code can be extended for up to 6 additional plants.
Do I need soldering skills?
No soldering is required — the kit uses a breadboard and jumper wires. All connections are plug‑and‑play. You'll learn circuit assembly without a soldering iron.
How do I analyse the logged data?
The data is saved as a CSV file on the microSD card. Simply insert the card into your laptop and open in Microsoft Excel, Google Sheets, or any data analysis tool like Python's pandas.
