Seed Viability Germination Incubator Variant 19 Kit with Arduino Uno + DHT22
Build a Precision Seed Germination Incubator with 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.
Program an Arduino-powered incubation chamber that holds a seedling tray at exactly the target temperature using PID logic, while logging humidity trends to an SD card. Track seed viability and germination rates with laboratory-grade precision, turning your biology or agri-science project into a data-driven investigation.
What You'll Build
A fully functional seed germination incubator that automatically heats a seedling tray to your setpoint temperature using a relay-driven heat mat and PID algorithm. The DS18B20 waterproof sensor feeds precise temperature data to the Arduino, while the DHT22 captures air humidity. An OLED displays live temperature and humidity, and every reading is timestamped and saved to a microSD card via the DS3231 real-time clock—perfect for analyzing germination conditions over days.
What You'll Learn
- Implementing PID control algorithms to maintain stable temperature for plant growth
- Wiring and programming digital temperature sensors (DS18B20) and humidity sensors (DHT22) with Arduino
- Logging timestamped environmental data to a microSD card using an RTC module
- Interpreting germination data to assess seed viability and optimize agricultural conditions

Who This Kit Is For
Designed for CBSE Class 11-12 students tackling biology or agriculture investigatory projects, this kit gives B.Tech ECE and Agri-Engineering undergraduates a hands-on introduction to precision farming. It’s equally valuable for ATL Tinkering Labs and Smart India Hackathon teams prototyping rural agri-tech solutions.
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, step‑by‑step guidance; you can also send a WhatsApp message for direct support from our team.
Can I use any heat mat with this incubator?
The kit includes a 5V relay module to control most standard 5V or 12V heating pads. A 5V USB heat mat is recommended and pairs safely with the included 9V battery snap and relay.
How accurate are the temperature and humidity readings?
The DS18B20 is factory‑calibrated to ±0.5°C, and the DHT22 offers ±2% RH accuracy. We provide calibration verification code in the build guide to ensure research‑grade data logging.
Can I upload data to the cloud instead of saving to SD?
This kit focuses on local microSD logging for offline field use. An advanced tutorial inside the companion app shows how to add an ESP8266 Wi‑Fi module (not included) for cloud uploads.
PID-controlled heat mat holds seedling tray at exact temperature. Humidity logged for germination study.
