Greenhouse Climate Monitor Lab Kit with Arduino Uno & DHT22 — Track Evaporation & Log Climate Data

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform a simple water dish into a precise environmental data station. Using an Arduino Uno, sensitive load cell, and DHT22 sensor, you’ll build a logger that captures how temperature and humidity drive evaporation—perfect for biology or physics investigatory projects. This kit turns your lab into a real-time greenhouse climate monitor that writes CSV files for analysis in Excel or Python.

What You'll Build

A self-contained climate logger that tracks mass loss from an open water dish alongside ambient temperature and humidity. The Arduino Uno reads the HX711 load cell’s tiny weight changes (0.1 g resolution), the DHT22 for air conditions, and a DS3231 real-time clock for timestamps. All readings appear on a 0.96‑inch OLED display and are saved to a microSD card, letting you run multi‑hour evaporation experiments with full data records.

What You'll Learn

• Calibrating an HX711 load cell for sensitive mass loss measurements
• Logging multi‑sensor data (temperature, humidity, time, weight) to an SD card
• Using a DS3231 RTC module to timestamp readings for time‑series analysis
• Displaying real‑time sensor values on an OLED for instant feedback

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for students who need a robust data‑logging platform for biology or physics investigatory projects. Ideal for CBSE Class 11-12 practicals, B.Tech first‑year mini‑projects, ATL Tinkering Lab mentors, and Smart India Hackathon teams building agritech or environmental monitoring prototypes. No prior data logging experience required, but basic Arduino familiarity helps.

Built and Backed by Compoden
