摘要
热释电红外传感器基于热释电效应,其内部的热电元件随温度的变化而发生极化,将热能转化为电信号从而向主机传输信号。整个系统以ARM Cortex-M3为处理器,单片机芯片选用的是性能较好的STM32系列芯片,探测器选用的是P228型号的热释电红外传感器,以蜂鸣器和发光二极管作为报警系统。通过调试使监测系统实现当警戒监测区域内出现目标物并被热释电红外传感器检测到时,将探测信息发送至单片机进行处理,最终控制报警器实现报警。
Pyroelectric infrared sensor is a kind of sensor based on pyroelectric effect.Its internal thermoelectric elements are polarized with the change of temperature,and heat energy is converted into electrical signals to transmit signals to the host computer.The whole system used ARM Cortex-M3 as the processor.STM32 series chips with better performance were used as the chip of MCU.The P228 pyroelectric infrared sensor was used as the detector,and buzzer and LED were also introduced as the final alarm system of the system.Through the debugging of the system,the monitoring system realizes that when the target object appears in the warning monitoring area and it is detected by pyroelectric infrared sensor,the data is sent to the single chip microcomputer for processing,and finally the alarm is controlled to alarm.
