The Plant Fairy (Smart Leaf Texture Microscope & Chlorophyll Tester)

Source:

Play 'The Plant Fairy' game. Inspect collected leaves under a digital USB camera microscope screen, test aromatic leaves (Mint, Tulsi, Coriander) with an NFC nose sensor, and measure leaf greenness with a color sensor.

Categorisation

Props & Materials Required

  • •Fresh leaves (Peepal, Neem, Rose, Mint, Tulsi, Mango, Coriander)
  • •Digital USB microscope / magnifier module with screen
  • •TCS3200 RGB color sensor (measures leaf greenness/chlorophyll)
  • •PN532 NFC reader module + NFC leaf cards
  • •ESP32 controller board
  • •DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Digital Microscope Inspection

Place a Peepal leaf under the USB microscope camera. Observe parallel vs. reticulate leaf veins on the monitor screen!

2

Aromatic Leaf Smell Test

Crush a Mint leaf and smell it. Tap the Mint NFC card on the smart reader. Speaker: 'MINT leaf! Aromatic herb used in chutneys and tea!'

3

Measure Greenness / Chlorophyll

Press the leaf against the TCS3200 color sensor. Sensor reads RGB green values.

4

Leaf Margin Classification

Sort leaves into 'Serrated Margins' (Rose/Neem) vs 'Smooth Margins' (Mango/Peepal) based on microscope view.

Why It Works & Notes

The Plant Fairy story teaches leaf diversity (round, long, triangular leaves; serrated vs. smooth edges). Magnifying leaf veins under a digital microscope and testing color greenness turns a garden walk into botany science.
