怎么将PIR与PSoC 3/5连接

你好朋友们，
这里是简单的基线设计接口PIR与PSoC 3/5。PIR传感器可用在CY3266A PrimStudio EVK上（PIR运动传感器，3POS MFG：GLOLAB公司MFG部分号：PIR325）。对EVK进行了很少的修改，使用了外部组件。本项目的总体设计具有原理图。
描述：PIR传感器的输出被发送到两个低通滤波器，一个截止为0.03Hz，另一个截止频率为30Hz。下截止滤波器用于对Δ∑ADC（配置在差模中）的一端的参考，AND输出给另一端的较高截止值。对信号进行适当采样，并将数字值与基线和阈值进行比较，以检测信号。
我附上这个项目。这个项目得到了很好的评价。

   Hello Friends,
    Here is simple Baseline design for interfacing PIR with the PSoC 3/5. The PIR sensor available on the CY3236A PIRMOtiON EVK was used(PIR Motion Sensor, 3POS Mfg by: Glolab Corp. Mfg part no: PIR325). Few modifications were done on the EVK and external components were used. The topdesign of the project has the schematic.
    Description: The output of the PIR sensor is sent to two low pass filters one with a cutoff of 0.03Hz and other with a cutoff of 30Hz. The lower cutoff filter was used an a reference for the one end of delta Sigma ADC( configured in differential mode) anmd the output of higher cutoff given to the other end. The signal is suitable sampled and the digital value compared with the baseline and the Threshold to signal the detection.
    I am attaching the project. The project is well commented.
