Abstract:
The Automatic Over Temp Detection and Alert circuit utilizes an NTC, LM393 comparator IC, and relay to detect and respond to temperature increases. The NTC functions as the temperature sensor, while the LM393 comparator IC processes the signal. In the absence of heat, the NTC stops conducting, keeping the LED and buzzer off. When temperature rises, the NTC starts conducting, activating the LED and buzzer to provide an alert.
Applications:
Most NTC-based circuits on the market use expensive or complex sensors. This circuit simplifies design by using readily available NTC sensors. The Automatic Over Temp Detection and Alert system ensures reliable performance in various electronics, automation, and educational applications, especially for environments in India.
Why This Circuit:
The circuit operates over a 5V DC supply, easily powered by a USB cable. NTC sensitivity can be adjusted by placing a soldering iron close to the NTC sensor. This makes it ideal for detecting temperature changes accurately in a wide range of electronic and automation projects.
Working Explanation:
The circuit design focuses on turning on an LED and buzzer when a temperature rise is detected. The NTC sensor acts as a temperature-sensitive resistor, while LM393 operates as a comparator IC. Relay acts as a switch, with normally closed contacts opening when activated. In normal conditions, the LED and buzzer stay off. Upon detecting increased temperature, the LED glows, and the buzzer sounds, alerting the user.
Building the Kit:
Read the manual thoroughly, assemble components on the PCB, and solder them in place. Resistors are identified by color codes, and capacitors are usually marked numerically. ICs are soldered into sockets to allow easy troubleshooting. Once assembled, connect a 5V DC power source and manually test by holding a soldering iron near the NTC to trigger the alert.
ICs Used:
LM393 – a popular and widely used dual differential comparator IC.
