The Living Organisms & Their Surroundings (Smart Biome Climate Chamber)

Source:

Compare extreme Earth biomes! Build a dual-chamber environmental simulator (Desert Biome vs Aquatic Biome). DHT22 sensors and water probes monitor temperature, humidity, and light, explaining organism adaptations.

Categorisation

Props & Materials Required

  • •Dual chamber biome model (Desert Chamber with heat lamp & Aquatic Chamber with water pump)
  • •2x DHT22 temperature & humidity sensors
  • •DS18B20 waterproof temperature probe
  • •LDR light intensity sensor
  • •ESP32 controller board
  • •16x2 LCD display screen
  • •DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Select Desert Biome Chamber

Turn ON Desert chamber heat lamp. DHT22 reads 'Temp: 42°C | Humidity: 15% (DRY ARID)'.

2

Inspect Cactus Model Adaptation

Moisture probe in cactus stem reveals 90% water storage! Speaker: 'Cacti have thick waxy stems and spine leaves to prevent evaporation!'

3

Select Mountain Biome Chamber

Switch to Mountain chamber. DHT22 reads 'Temp: 8°C | High Altitude Wind'.

4

Adaptation Comparison Audio Report

LCD displays 'DESERT vs MOUNTAIN BIOME COMPARISON'. Speaker narrates how Yaks develop thick fur to trap heat!

Why It Works & Notes

Organisms adapt to specific abiotic conditions (desert cacti store water in stems, mountain pine trees have waxy needle leaves). Monitoring live climate data in contrasting chambers shows how abiotic factors shape biotic adaptations.
