Senzorul Doppler Radar si Arduino<\/p>\n\n\n\n

Vom folosi un Arduino si un senzor de mi\u0219care doppler RCWL-0516 pentru a construi un radar doppler cu Arduino.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Va scoate automat \u00een mod continuu un semnal TTL de nivel \u00eenalt atunci c\u00e2nd exist\u0103 mi\u0219care. 360 de grade f\u0103r\u0103 detectare a unghiului orb \u0219i distan\u021b\u0103 de detectare maxim\u0103 de 7 m. <\/p>\n\n\n\n

Este perfect pentru comutatorul de lumin\u0103 cu senzor de mi\u0219care cu microunde, juc\u0103rii cu senzor uman, dispozitive inteligente de securitate etc.<\/p>\n\n\n\n

Din fi\u0219a de date \u0219i pinout-ul RCWL-0516, \u0219tim c\u0103 acest senzor ofer\u0103 o putere mare atunci c\u00e2nd este detectat\u0103 mi\u0219care. Pinul CDS poate fi folosit pentru a activa detectarea mi\u0219c\u0103rii, \u00een acest exemplu men\u021binem acel pin ridicat, adic\u0103 mereu pornit.<\/p>\n\n\n\n

Un cod exemplu :<\/strong><\/p>\n\n\n\n

\/* Arduino Microwave Radar Motion Sensor Interface
ROBOROMANIA
roboromania.ro *\/<\/p>\n\n\n\n

int Sensor = 2; \/\/Input Pin
int LED = 13; \/\/ Led pin for Indication
int flg = 0; \/\/Change detection flag
void setup() {
Serial.begin(9600);
pinMode (Sensor, INPUT); \/\/Define Pin as input
pinMode (LED, OUTPUT); \/\/Led as OUTPUT
Serial.println(„Waiting for motion”);
}
void loop() {
int val = digitalRead(Sensor); \/\/Read Pin as input<\/p>\n\n\n\n

if((val > 0) && (flg==0))
{
digitalWrite(LED, HIGH);
Serial.println(„Motion Detected”);
flg = 1;
}
if(val == 0)
{
digitalWrite(LED, LOW);
flg = 0;
}
delay(100);
}<\/p>\n\n\n\n

Test:<\/strong><\/p>\n\n\n\n

Deschide\u021bi monitorul serial la viteza de transmisie de 9600 \u0219i face\u021bi o mi\u0219care \u00een fa\u021ba senzorului. Observa\u021bi LED-ul 13 \u0219i monitorul serial.<\/p>\n\n\n\n
