NTC Temperature Sensor And Fire Alarm

Time:2021-03-30 Views:998
Fire alarm is one of the indispensable equipment in modern cities, and it is indispensable in high-rise residential buildings, hotels and office buildings. When a fire occurs, the alarm is suddenly particularly important. With a fire alarm, you can even notify the arrival of firefighting at the first time, and it can keep residents away from the ground and stay away from danger. Reducing fires in homes and public places and reducing people’s property losses are the most important and crucial role.
 
The fire alarm monitors the surrounding temperature through the NTC temperature sensor. Since the combustion will generate a lot of heat when a fire occurs, the surrounding temperature will increase rapidly. The NTC temperature sensor will convert the change of the surrounding environment temperature into an electrical signal. The processor judges whether a fire has occurred by judging the magnitude of the electrical signal. Once a fire occurs The alarm will sound automatically, so the NTC temperature sensor plays a key role in the fire alarm.
