Indoor Plant Monitor Kit: Arduino Soil Moisture & Temperature Data Logger
Indoor Houseplant Monitor Kit – Log Soil Moisture & Temperature with Arduino for Hands‑On STEM Agriculture
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 curiosity about your houseplants into a data‑driven science experiment. This kit lets you wire up an Arduino Nano with soil moisture and temperature sensors, then log readings automatically to a microSD card. Over days, you’ll see exactly when soil dries out, how temperature swings affect growth, and what your green friends really need — all while building real‑world electronics skills.
What You'll Build
Assemble a compact monitor that sits beside your plant tray. Two moisture probes track water levels in different soil samples, while the DS18B20 sensor records ambient temperature. Every few minutes, the Arduino writes a timestamped entry to the SD card, creating a CSV file you can graph in any spreadsheet tool. The result is a long‑term dataset that reveals patterns no single glance can catch — ideal for a winning science fair exhibit or serious classroom investigation.
What You'll Learn
- Wire and read analog soil moisture sensors to quantify “dry” vs. “wet”
- Interface a digital temperature sensor using the OneWire protocol
- Manage SD card storage with the SPI library and create structured CSV logs
- Interpret environmental data to understand plant needs across multiple days

Who This Kit Is For
Designed for CBSE Class 9–12 students tackling agriculture‑based science projects, ATL Tinkering Lab innovators, and hobbyists as young as 10 who want to move beyond theory. The step‑by‑step build and ready‑to‑upload code make it equally suitable for B.Tech first‑year students exploring sensor integration. If you’ve ever wondered whether your plants feel the heat, this kit gives you the answer.
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 launch the AI companion that knows every connection, line of code, and common issue in this kit. If you prefer a human, WhatsApp our support team and you’ll get a reply from a builder who has assembled this exact project.
Can I monitor more than one plant at once?
Yes, the kit includes two soil moisture sensors and three seed trays, so you can compare readings from different plants or soil types side‑by‑side. The Arduino reads both sensors in each logging cycle.
How long can it log data?
The 4GB microSD card stores millions of lines. Logging every 5 minutes, you’ll have months of capacity. A full log from a 7‑day experiment uses only a few kilobytes.
Do I need coding experience?
Not at all. We provide the Arduino sketch pre‑written and commented. You’ll upload it, learn what each section does, and can tweak logging intervals without coding from scratch.
