Chhota's House (Smart Shelter Thermal Insulation & Roof Model)
Source:
Construct mini shelter models (Thatch Roof, Tin Sheet Roof, Brick/Concrete Roof, Ice Igloo). Place heat lamps above shelters and measure indoor temperature with DS18B20 thermal probes to find the coolest roof material.
Categorisation
Props & Materials Required
- •4 mini house models (Thatch/Straw, Corrugated Tin, Brick/Concrete, Foam Igloo)
- •4x DS18B20 waterproof digital temperature sensor probes
- •Incandescent heat lamp (simulated hot Sun)
- •ESP32 controller board
- •16x2 LCD display screen
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Inspect Shelter Materials
Compare 4 mini homes: Thatch/Straw Roof (Kutcha house), Tin Roof, Concrete Flat Roof (Pucca house), Igloo.
Insert Thermal Probes
Place DS18B20 temperature probes inside each house model.
Switch ON Heat Lamp
Turn on the overhead heat lamp for 3 minutes to simulate scorching afternoon sun.
Compare Indoor Temperatures
LCD displays: Tin Roof = 42°C (HOT!), Thatch Roof = 28°C (COOL!). Speaker explains: 'Straw thatch traps air pockets, keeping Chhota's house cool!'
Why It Works & Notes
Shelters vary by climate (sloping roofs in rainy areas, thick mud walls in hot deserts). Measuring real internal temperature changes under a heat lamp proves why thatch/mud walls keep homes cool while tin roofs trap heat.
