| 2) Beginner-based temperature switch project |
| This is a simple circuit diagram of temperature switch project which works as a simple fire alarm indicator. This temperature switch uses a few discrete components to trigger a buzzer when the temperature of the surrounding increases. This electronic project works on the simple principle that when the temperature surrounding the germanium diode increases, the back resistance decreases sharply.
