烟雾传感器就是通过监测烟雾的浓度来实现火灾防范的，烟雾报警器内部采用离子式烟雾传感，离子式烟雾传感器是一种先进技术，工作稳定可靠的传感器，被广泛运用到各种消防报警系统中，性能远优于气敏电阻类的火灾报警器。
In this monitoring system, a digital temperature sensor DS18B20 withsingle line and an ion smoke sensor 1412 are implemented as the detectors oftemperature and smoke respectively.
该监测系统采用单线数字温度传感器DS18B20和1412离子感烟器作为温度和烟雾传感器。
