Simple Fire Alarm Circuit Diagram. Here thermistor is used as a fire detector. The circuit diagram of this simple fire alarm project is shown in the following image.
Thermistors are temperature dependent resistors i e. Circuit 1 simple fire alarm circuit circuit diagram. There are many types of a small fire alarm that exists like lm358 alarm ne555 timer alarm lm341 alarm transistor type alarm and few more in this project i will going to use the lm358 op amp ic.
The resistance of a thermistor varies.
I will also show you the detailed circuit schematic circuit connections circuit working video tutorials and also its applications.
