Greenhouse Rain Logger Kit v2 — Characterize LDR, Thermistor, Strain Gauge, and BMP280 Pressure Sensor with Arduino Nano

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 standard Arduino Nano into a full greenhouse monitoring station. Over 4–5 hours, you’ll wire up four distinct sensors, capture real-world signals, and plot resistance-versus-physical-quantity curves—the same method engineers use to calibrate industrial IoT systems. This kit brings the physics of sensing out of textbooks and onto your breadboard.

What You'll Build

A unified data logger that reads light intensity from three LDRs, temperature from three thermistors, strain from a foil gauge, and atmospheric pressure via the BMP280. You’ll log these readings to the serial monitor and export them for graphing in a spreadsheet, then interpret the non-linear response of each sensor. The result is a modular, expandable node that mimics how commercial greenhouses monitor microclimate variables.

What You'll Learn

• Characterize LDR, thermistor, strain gauge, and BMP280 sensors — measure and graph resistance changes against light, temperature, force, and pressure
• Program Arduino Nano to read analog voltages, apply voltage divider formulas, and convert raw values to physical units
• Design a multi-sensor data logger with serial output ready for spreadsheet import and analysis
• Interpret non-linear sensor curves and understand calibration techniques used in environmental monitoring and IoT agriculture

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

B.Tech ECE, EEE, and instrumentation students who need a ready-to-go lab for sensor characterization will find this kit built to match their curriculum. CBSE Class 12 physics learners can confidently tackle resistance and potential divider practicals, while ATL Tinkering Lab mentors get a greenhouse-themed project that connects electronics to environmental science. Smart India Hackathon teams building precision agriculture prototypes can use the strain gauge and BMP280 for real-time weight and pressure monitoring.
