Add a second distance sensor to the same arduino?

[barduino]

@Cliff-Karlsson

It should be something like this

Define new child id and pins for the new sensor

#define SONAR_A_CHILD_ID 1
#define SONAR_B_CHILD_ID 2
#define SONAR_A_TRIGGER_PIN  6  // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define SONAR_A_ECHO_PIN     5  // Arduino pin tied to echo pin on the ultrasonic sensor.

#define SONAR_B_TRIGGER_PIN  8  // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define SONAR_B_ECHO_PIN     7  // Arduino pin tied to echo pin on the ultrasonic sensor.

Then instantiate 2 sonars

NewPing sonar_A(SONAR_A_TRIGGER_PIN, SONAR_A_ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.

NewPing sonar_B(SONAR_B_TRIGGER_PIN, SONAR_B_ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.

Now instantiate 2 messages and 2 lastDistance variables

MyMessage SONAR_A_msg(SONAR_A_CHILD_ID, V_DISTANCE);
int SONAR_A_lastDist;
MyMessage SONAR_B_msg(SONAR_B_CHILD_ID, V_DISTANCE);
int SONAR_B_lastDist;

Presenting the sensors

// Register all sensors to gw (they will be created as child devices)
  present(SONAR_A_CHILD_ID, S_DISTANCE);
  present(SONAR_B_CHILD_ID, S_DISTANCE);

Finally the loop section

void loop()      
{     
  int SONAR_A_dist = metric?sonar_A.ping_cm():sonar_A.ping_in();
  Serial.print("Ping Sonar A: ");
  Serial.print(SONAR_A_dist); // Convert ping time to distance in cm and print result (0 = outside set distance range)
  Serial.println(metric?" cm":" in");

  if (SONAR_A_dist != SONAR_A_lastDist) {
      send(SONAR_A_msg.set(SONAR_A_dist));
      SONAR_A_lastDist = SONAR_A_dist;
  }

int SONAR_B_dist = metric?sonar_B.ping_cm():sonar_B.ping_in();
  Serial.print("Ping Sonar B: ");
  Serial.print(SONAR_B_dist); // Convert ping time to distance in cm and print result (0 = outside set distance range)
  Serial.println(metric?" cm":" in");

  if (SONAR_B_dist != SONAR_B_lastDist) {
      send(SONAR_B_msg.set(SONAR_B_dist));
      SONAR_B_lastDist = SONAR_B_dist;
  }

  sleep(SLEEP_TIME);
}

Other considerations:

• Since sonar uses sound it might be a good idea to put some wait between the pings

Thanks for the help, last question witch complicates the whole thing some more.

If I want to also have two PIRs connected to the same arduino and want to use both PIRs as interrupts so that the sensor sleeps until one of the PIRs is activated.

When the sensor wakes up after PIR movement PIRs should be put to sleep for 1min and the distance sensors would start.

This is the Motion sketch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each

 * network topology allowing messages to be routed to nodes.

@Cliff-Karlsson

The "trick" is this line

// Sleep until interrupt comes in on motion sensor. Send update every two minute. 
  sleep(INTERRUPT,CHANGE, SLEEP_TIME);

You can use something like this

int8_t sleep(uint8_t interrupt1, uint8_t mode1, uint8_t interrupt2, uint8_t mode2, unsigned long ms=0);

Take a look in the MySensors API page under "sleeping" http://www.mysensors.org/download/sensor_api_15

Cheers

[Cliff Karlsson]

@barduino said:

int8_t sleep(uint8_t interrupt1, uint8_t mode1, uint8_t interrupt2, uint8_t mode2, unsigned long ms=0);

Ok so if PIRs are connected to PIN 10 and PIN 11 I would use:

int8_t sleep(uint8_t 10, uint8_t CHANGE, uint8_t 11, uint8_t CHANGE, unsigned long ms=0); 

?

[Cliff Karlsson]

Ok I got the two distance sensors to work and now I am trying to also add a motion sensor. First question, I read in the motion sensor sketch that only pin 2 and 3 generates interrupts and my radio is connected to pin 2 already. But I also recall reading something about pin 2 on the radio is not used so that means that I can use pin 2 and 3 for the PIRs, right?

This is what I have come up with for now but I know there is some errors in it and I have not quite figured out the sleep part yet.

And in the loop do I use ?

if(tripped){"do distance stuff"}

This is what I have go so far I added some white lines to the right of the parts that I added to the working distance sketch:

@Cliff-Karlsson You can only use pin2 and pin3 as interrupt pins. You don't need to connect the NRF24L01+ to pin 2. So you can use both. I'm doing this with my doorbell works perfect.

Notice. If you're node also receives messages from the gateway, you wont be able to put the node to sleep. MySensors currently doesn't support wake up on message arrival. That's why pin2 can be used for connecting sensors.

I hope this makes sense ;-)

[TheoL]

@Cliff-Karlsson I'm not sure if you're aware of this. But in your setup, you need to start the MySensors communication. Like the gw.begin() and the presentation of the child's.

I don't see this in your code:

void setup()  
{ 
  metric = getConfig().isMetric;
  pinMode(MOTION_A_TRIGGER_PIN, INPUT);      // sets the motion sensor digital pin as input ----------------------
}

No offence. Just trying to help you.

[Cliff Karlsson]

Absolutley none offence taken, I really suck at coding and my main methods are copy/paste and click on verify to check if it worked.

I am using the developer branch that does not use the gw. stuff if that is what you mean?

This is what I have tried for now but ofcourse it does not work.

@Cliff-Karlsson I'm sorry I haven't played with the development branch. I'm just using 1.5.4. But the part abount interrupts and pin2 and 3 stays the same. It's just how the Arduino works.

[TheoL]

@Cliff-Karlsson I think you want this:

MyMessage msg(MOTION_A_CHILD_ID, V_TRIPPED);

boolean metric = true; 

instead of

MyMessage msg(MOTION_A_msg, V_TRIPPED);

boolean metric = true; 

[Cliff Karlsson]

Thanks, sorry fore code-spamming but it feels like I am starting to get close to the first step witch is a succesful verify.

@Cliff-Karlsson To me that's what this community is about. I'll have a loop. But no promise, as said before I haven't played with the development branch yet. But I do understand the compiler error

[Cliff Karlsson]

@TheoL said:

Thanks.
And if unclear I am trying to achieve in the end is:

When PIR senses motion, activate both distance sensors for 30 seconds and deactivate PIR.
After 30 seconds deactivate distance sensors and activate PIR again.

[TheoL]

@Cliff-Karlsson Is it giving the error on the first or the second sleep?

I have to compliment @Hek and the other guys. They've made MySensors easier to program. The branch looks really great. Love it.

[TheoL]

@Cliff-Karlsson I think I found it.

it's in this part

    sleep(SLEEP_TIME);
  }
            } // <--------- this ends the loop() method
//else{
  // Sleep until interrupt comes in on motion sensor. Send update every two minute. 
  sleep(INTERRUPT,CHANGE, MOTION_SLEEP_TIME); // <---- so this is not in the method
//}
} // <-------- int this is also outside of the loop method

Change it to:

    sleep(SLEEP_TIME);
  }
 //           }  // comment brace
//else{
  // Sleep until interrupt comes in on motion sensor. Send update every two minute. 
  sleep(INTERRUPT,CHANGE, MOTION_SLEEP_TIME);
//}
}

[Cliff Karlsson]

After commenting the bracket I get : 'DIGITAL_INPUT_SENSOR' was not declared in this scope

[TheoL]

@Cliff-Karlsson I'm sorry would love help you further. But it's getting late over here and my better half wants me to turn off the laptop.
