This project uses an LM35 temperature sensor with Arduino Uno to monitor temperature from 0–100°C.
- Linear conversion of LM35 output (0–5V)
- Alarm at 45.1°C
- LED indicators (green, amber, red, orange)
- 7-segment voltage display
- Arduino Uno
- LM35 sensor
- LM358p op amp
- LEDs + buzzer
- 7-segment display
The system reads analog voltage from LM35, converts it to temperature, and triggers outputs based on thresholds.
