HVAC Performance Monitor Kit v3 — Arduino-Powered Hyperspectral Vegetation Analyzer

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

Imagine walking through a field or greenhouse and instantly knowing which plants are stressed before any visible symptoms appear. This kit lets you build a handheld Hyperspectral Vegetation Analysis Camera (HVAC) that reads 18 discrete wavelengths of reflected light from leaves, then computes the Normalized Difference Vegetation Index (NDVI) and other stress indicators — giving you laboratory-grade plant health data in seconds. Built around the AS7265x tri‑spectral sensor array and an Arduino Mega, the device logs readings with GPS‑ready timestamps and displays spectral profiles on a 2.4-inch TFT screen.

What You'll Build

You will assemble and calibrate a full-spectrum reflectance meter that quantifies chlorophyll content, water stress, and canopy density non‑destructively. The finished HVAC unit can be taken directly to field plots, polyhouses, or research stations. After each measurement, spectral signatures save to a MicroSD card for downstream analysis in tools like QGIS or Python. This is not a toy; it’s a scientific instrument that replaces multi‑lakh spectroradiometers with open‑source components.

What You'll Learn

• Interfacing the 18‑channel AS7265x sensor with Arduino Mega over I²C and interpreting raw spectral counts
• Translating visible and near‑infrared reflectance values into NDVI, PRI, and other stress indices
• Designing a custom PCB layout and soldering a rugged, field‑portable instrument
• Integrating environmental sensors (temperature, humidity, atmospheric pressure) to correct spectral measurements

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This is built for serious makers and researchers – B.Tech ECE/EEE students fabricating their own remote‑sensing payloads, M.Tech scholars in precision agriculture, and scientists at ICAR or state horticulture departments. It fits perfectly into Smart India Hackathon teams working on crop stress detection, as well as environmental monitoring lab projects at IIT, NIT, VIT, or BITS Pilani. If you need to replace expensive multispectral cameras with a reproducible, open‑source instrument, this kit is your launchpad.
