Automatic Temp Control Exhaust Fan DIY Experiments Science Project Model STEM KIT (Assembled), 100% Tested

Abstract:
This Automatic Temperature Control Exhaust Fan kit uses an NTC thermistor, LM393 comparator IC, and a relay to automatically detect temperature changes and activate the fan. It includes a red LED indicator that glows when the temperature rises and the fan is operational.

How It Works:

• NTC Thermistor: Acts as a temperature detector. Its resistance decreases with temperature rise.
• LM393 Comparator IC: Compares input signals to activate the relay.
• Relay: Acts as a switch to control the fan and LED based on the temperature detected.

Circuit Applications:
The circuit ensures efficient temperature regulation, making it suitable for applications like:

• Automation and robotics projects.
• Educational science experiments.
• Practical use in controlling small exhaust fans in temperature-sensitive environments.

Why Choose This Kit:

• Optimized for Indian environmental conditions.
