Seed Viability Germination Incubator Kit with Arduino Uno + DHT22
Precision Seed Germination Incubator Kit with Arduino Uno – PID Heat Mat Control & Humidity Data Logger
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Study seed viability with the rigour of a botanist using this Arduino-powered germination incubator. By precisely regulating a heat mat through a PID algorithm and logging temperature-humidity data onto a microSD card, you replicate the conditions of professional seed testing labs. This kit is purpose-built for CBSE Biology investigatory projects, Smart India Hackathon prototypes, and ATL Tinkering Lab experiments in agriculture automation.
What You'll Build
A complete, sensor-driven germination chamber that maintains a setpoint temperature with accuracy under ±0.5°C. The waterproof DS18B20 probes the soil or substrate temperature, the DHT22 monitors ambient humidity, and the relay switches an external heat mat on and off according to the PID control loop. A DS3231 RTC timestamps every data point written to the SD card, while the 0.96‑inch OLED displays real‑time readings. Seedling trays are not included, but the build can accommodate standard trays placed above the heat source, creating a stable microclimate ideal for germination rate studies.
What You'll Learn
- Implement a PID control loop on Arduino to regulate temperature with feedback from the DS18B20 sensor
- Interface multiple digital sensors (DHT22, DS18B20) and log structured data to a microSD card
- Integrate a DS3231 real‑time clock for accurate timestamps and drive an OLED display for live monitoring
- Design a smart farming prototype applicable to agriculture IoT, CBSE project work, and hackathon challenges

Who This Kit Is For
CBSE Class 11‑12 students (Biology, Physics, or Electronics) preparing investigatory projects on seed viability. B.Tech ECE/EEE undergraduates prototyping agricultural automation for Smart India Hackathon. ATL Tinkering Lab facilitators running experiments in controlled environment agriculture. Anyone curious about combining Arduino with real‑world sensor data to explore IoT‑enabled farming.
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?
The AI companion provides interactive guidance for every connection and calibration step. You can also send a message on WhatsApp; our team responds within a few hours to get you unstuck.
Does the kit include the heating mat or seedling tray?
The kit does not include an external heat mat or tray — it is designed to control a standard 5V‑12V heating mat via the relay module. Common seed germination trays are compatible and available at any nursery or supplier.
How do I log germination data to the SD card?
The microSD module writes a CSV file with temperature, humidity, and a timestamp from the DS3231 RTC at a 1‑minute interval. You can open the file in Excel or Google Sheets to graph viability rates and environmental conditions.
Can I view sensor data without a computer?
Yes, the 0.96‑inch OLED displays real‑time temperature, humidity, and the current PID setpoint. For full historical logging, you’ll need to transfer the microSD card to a PC, but the OLED gives instant feedback during experiments.
PID-controlled heat mat holds seedling tray at exact temperature. Humidity logged for germination study.
