How to code for multiple PIR sensors.

Post by chromedragon » Sun May 08, 2016 9:09 am

Hello,

I have two PIR sensors (Sensein and SenseOut). In the past i built individual relay circuits which worked well but this time I wanted to use the Arduino. The sensors have delay adjustments so they provide a high for however I set these adjustments.

The sensors seem to be working correctly, but when SenseOut is triggered, I get Outdoor lamp ON then Outdoor Light OFF. When SenseIn is triggered, I only get Indoor Lights On.

I know it is the way I coded the sensors, and something to do with the LockLow, but frankly, I am having difficulty putting my head around it. Here is that code:

// This is Indoor sensor

if(digitalRead(SenseIn) == HIGH){
digitalWrite(LampIn, LOW); //Interior lamp ON
if(lockLow){
// Wait for transition
lockLow = false;
Serial.println("\n\n");
Serial.print("Indoor Lights ON");
Serial.println(" ");
Serial.println("\n\n");
delay(50);
}
takeLowTime = true;

}
// This is Outdoor sensor

if (digitalRead(SenseOut) == HIGH) {
digitalWrite(LampOut, LOW); //Exterior Lamp ON
if (lockLow) {
// Wait for transition
lockLow = false;
Serial.println("\n\n");
Serial.print("Outdoor Light ON");
Serial.println("\n\n");
delay(50);
}
takeLowTime = true;

}

if(digitalRead(SenseOut) == LOW){
digitalWrite(LampOut, HIGH); //The relay turns off
if(takeLowTime){
lowIn = millis(); //save the time of the transition from high to LOW
takeLowTime = false; //make sure this is only done at the start of a LOW phase
}
}
//if the sensor is low for more than the given pause,
//we assume that no more motion is going to happen
if(!lockLow && millis() - lowIn > pause){
//makes sure this block of code is only executed again after
//a new motion sequence has been detected
lockLow = true;
Serial.println("\n\n");
Serial.print("Outdoor Light OFF");
Serial.println("\n\n");
delay(50);
}

if(digitalRead(SenseIn) == LOW){
digitalWrite(LampIn, HIGH); //The relay turns off
if(takeLowTime){
lowIn = millis(); //save the time of the transition from high to LOW
takeLowTime = false; //make sure this is only done at the start of a LOW phase
}
}
//pause for any motion
if(!lockLow && millis() - lowIn > pause){
//makes sure this block of code is only executed again after
//a new motion sequence has been detected
lockLow = true;
Serial.println("\n\n");
Serial.print("Indoor Light OFF");
Serial.println("\n\n");
delay(50);
}



Any help in correcting this issue would greatly be appreciated.
