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.
