This fire sensor circuit exploits the temperature sensing property of an ordinary signal diode IN 34 to detect heat from fire. At the moment it senses heat, a loud alarm simulating that of Fire ...

A few simple components are all it takes to create an over-temperature alarm. The circuit in Figure 1 requires only an ordinary negative-temperature-coefficient (NTC) thermistor, two common ICs ...

For Celsius degrees the output voltage of IC2 is set with P1 at 2.73 V when the temperature of IC1 is 0°C. The calibration of the temperature indicator at 100°C is done by comparing it with a ...
