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.
- Works on a reliable 5V DC power supply.
- Simplified circuit design for easy assembly and testing.
- Comprehensive instructions provided for a smooth DIY experience.
How to Assemble and Test:
- Read the manual thoroughly to understand the circuit and components.
- Solder the components onto the PCB following the instructions.
- Test the kit by exposing the NTC thermistor to heat, such as a soldering gun. The LED should glow, and the fan should turn ON automatically.
Components Included:
- LM393 Comparator IC
- NTC Thermistor
- Red and Green LEDs
- Variable resistor (10k Ohm)
- 5V USB cable
- Mini Exhaust Fan
