Smart Garden Watering Kit v6
Build a 10-Sensor Garden Monitoring System with Arduino Mega – Log Everything to SD
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 a single outdoor unit that captures every critical environmental parameter in your garden — from air quality and UV index to soil moisture and rainfall — all timestamped and saved to a microSD card. The Smart Garden Watering Kit v6 turns that into reality with a sensor-packed Arduino Mega build. Designed for serious hobbyists and engineering students, this kit moves beyond simple soil moisture alerts to create a permanent, deployable data logger you can tune for local conditions.
What You'll Build
You’ll solder and assemble a rugged multi-sensor board that reads 10 distinct parameters: temperature, humidity, barometric pressure, air quality (MQ-135), ambient light, UV intensity, rain detection, soil moisture, sound level, and vibration. Live readings scroll on the OLED, while every data point is written in CSV format to a microSD card — each line stamped with date and time from the DS3231 RTC. The result is a self-contained field monitor you can leave running for weeks, then pull the SD card for analysis on your laptop.
What You'll Learn
- Interface analog and digital sensors (I2C, SPI, 1-Wire) with the Arduino Mega’s abundant GPIO
- Fuse data from 10 sensors into a single, timestamped log file on SD card
- Solder components onto prototype PCBs for a permanent, weather-resistant board
- Calibrate gas, UV, and sound sensors using reference points for accurate environmental readings

Who This Kit Is For
B.Tech ECE/EEE students looking for a final‑year project that combines IoT, sensor fusion, and data logging. Smart India Hackathon teams building agriculture‑tech or environmental monitoring solutions. ATL Tinkering Lab mentors who need an advanced, soldering‑intensive kit for senior students. Also fits IIT/NIT research interns prototyping long‑term field loggers, and CBSE Class 12 students with prior Arduino experience who want to push beyond basic breadboard circuits.
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 built on this project's exact code and wiring; it can debug sensor readings or soldering issues. If you still need human help, WhatsApp support is included.
Can I run this kit on solar power for outdoor use?
The kit ships with a 9V battery snap for initial testing, but the Mega can be powered via Vin with a 7-12V source. Guidance is provided to connect a solar charge controller and LiPo battery (not included) for permanent outdoor logging.
Does the kit include code for all sensors at once?
Yes, a fully integrated sketch is pre‑loaded on the AI companion that reads all sensors, updates the OLED, and logs to SD every few seconds. You can modify intervals or disable sensors directly through the AI prompts.
How reliable is the soil moisture sensor in Indian soil conditions?
The resistive sensor works well in most Indian soils, but readings will drift with salinity. The AI guide walks you through calibration using a dry/wet test in your specific soil (black cotton or red loam) so that thresholds are meaningful.
