The application of NTC thermistor in the fire alarm reporter.Smart Microwave Sensor switch company

　　In our lives, security issues have always been important, but everyone always cannot avoid negligence on safety in safety issues. At this time, various sensors are well collected and processed in good. The advantages of the side are highlighted.

　　Temperature is a basic physical quantity, and everything in nature is closely related to temperature. Temperature sensor is the earliest development and widely used sensor. The electronic components used in the temperature sensor are our most common NTC thermistor.

　　The most common fire alarm reporter in our lives plays a key role in preventing fires from families and public places, reducing people's property losses, and a key.

　　The role of NTC thermal resistance in the fire alarm reporter -temperature monitoring.

　　The fire alarm device monitors the surrounding temperature through the NTC thermal resistance. Once the fire occurs, the alarm will be automatically issued. The reason why the thermistor is used is because the resistance value of the NTC thermistor will change with the temperature. Compared with other components, the temperature perception will be more sensitive.

　　Place the thermistor sensor with flammable items or monitored items. When the temperature of the monitoring items is too high, the thermal resistance resistance value is reduced, and the current increases through the route to trigger other settings. When people hear the sound of bees, they can know that they react to avoid the occurrence of fire, thereby achieving an automatic alarm function.
