RCWL-0516 微波雷達感應開關模組 人體感應探測器

商品說明

RCWL-0516是一款採用多普勒雷達技術，專門檢測物體移動的微波感應模組。該模塊具有靈敏度高，感應距離遠，可靠性強，感應角度大，供電電壓範圍廣等特點。廣泛應用於各種人體感應照明和防盜報警場合。

• 採用專用信號處理控制晶片 RCWL-9196
• 寬工作電壓範圍4.0~28V
• 與傳統紅外感應PIR相比，具有穿透探測能力
• 封鎖時間，距離可調
• 可輸出3.3V電壓

Arduino 範例

• GND – [connects to ground]
• OUT [connects to digital input]
• VIN – [connects to 5v]

int ip = 8;
int val = 0;
int led = 13;

void setup() {
 Serial.begin(9600);
 pinMode (ip, INPUT);
 pinMode (led, OUTPUT);

}

void loop() {
 val = digitalRead(ip);
 Serial.println(val, DEC);
 if(val >0)
 {
 digitalWrite(led, HIGH);
 }
 else
 {
 digitalWrite(led, LOW);
 }
 delay(1000);
}

RCWL 0516 Microwave Motion Sensor技術補充（英文）

以下為原廠英文技術說明，提供進階使用者參考。

The RCWL-0516 microwave radar motion sensor module is a low cost sensor . There is quite a lack of information on the module online, at least not that I could find, so I’m compiling what I could find and posting it all here in this article.
