Abstract:
The Heat Sensor using NTC circuit is designed using a readily available NTC thermistor and a comparator IC LM393. The NTC functions as a temperature sensor, while IC LM393 is used as a comparator. In the absence of heat, there is no rise in temperature of the NTC, leading to no conductivity and an LED staying off. When the temperature rises, the NTC conducts, activating the LED.
Application of the Circuit:
Many NTC-based circuits on the market use costly components and complex circuitry. This Heat Sensor using NTC circuit employs a readily available NTC thermistor, reducing costs and simplifying the setup. The circuit detects temperature and automatically activates the LED when there is a rise in temperature, making it ideal for automation and educational projects.
Why this Circuit:
The NTC thermistor is easy to source and modify for varying temperature ranges. The circuit operates on a 5V DC supply, making it suitable for a wide range of electronic projects.
Explained Working of Circuit:
The circuit uses a dual comparator IC LM393. The NTC thermistor functions as the temperature sensor, which connects to the comparator. When temperature increases, the NTC conducts, activating the LED. In contrast, if the temperature remains low, the LED stays off.
How to Build:
- Read the provided manual thoroughly.
- Study the circuit and PCB layout.
- Identify and solder components onto the PCB, ensuring correct polarity.
- Use IC sockets for easy troubleshooting.
- Test the kit using a 5V DC power source and manually apply heat to the NTC.
ICs Used:
The only IC used here is LM393, a dual differential comparator IC commonly used in temperature-related circuits.
