RCWL-0516 微波雷達感應開關模組人體智能感應探測器

RCWL-0516 微波雷達感應開關模組人體感應模塊智能感應探測器感應距離大約5-7米

RCWL-0516 微波雷達感應開關模組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塊。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芯片 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]

#include <VirtualWire.h>

#define PIN_RADAR 2
#define PIN_TX 9
#define PIN_LED 13

void setup() {
  Serial.begin(9600);
  pinMode(PIN_LED, OUTPUT);
  vw_set_tx_pin(PIN_TX);        // Arduino pin to connect the receiver data pin    
  vw_setup(6000);               // bps connection speed
}

int rv = -1;

void loop() {
  digitalWrite(PIN_LED, HIGH);
  int v = digitalRead(PIN_RADAR);
  if (v != rv) {
    rv = v;
    char msg[20];
    sprintf(msg, "R %lu %d", millis() / 1000, v);
    vw_send((uint8_t *)msg, strlen(msg));
    Serial.println(msg);
    vw_wait_tx();        // Wait to finish sending the message
  }
  digitalWrite(PIN_LED, LOW);
  delay(100);
