1.模块介绍

该模块可以用来检测人体存在/移动目标感应。

PIN	功能	备注
VCC	供电	2.7-4.8V
GND	接地	-
OUT	信号输出	输出高低电平（0/2.2V）
P2	GPIO2	接收增益档位选择（悬空/拉低选择）
P3	GPIO3	延时时间档为选择（悬空/拉低）

• 硬件接线

2.人体存在检测

• 案例说明
  使用该模块实现人体检测，当检测到有人活动时，会播报语音，同时会点亮led灯，当没有人活动时，熄灭小灯。当前音频文件被放在工程文件中，也可以放在SD卡中。

• main.py

from driver import GPIO
import utime as time
import audio

led=GPIO()
led.open("led1")

radar=GPIO()
radar.open('radar')

aud=audio.Audio()
aud.set_pa()
aud.setVolume(5)

while True:
    #当检测到人体活动，相应的引脚会输出高电平
    if radar.read()==1:
        print("detect body") 
        aud.play('/data/pyamp/detect_body.mp3')
        led.write(1)
    else:
        print("no body")
        led.write(0)

    time.sleep(1)
