Door, Motion and Temperature Sensor

[CaptainZap]

@petoulachi @BulldogLowell Glad to hear there is some progress, in regards to my issue and hopefully this is step in the right direction. I'm positive that we're not alone in our need to create multisensors, both powered and battery operated, as arduinos offer too many possibilities to limit yourself to just a single type of device :)

you don't have a working sketch?

[CaptainZap]

@BulldogLowell Temperature isn't working, and is never updated on the Vera interface :|

[BulldogLowell]

try something like this, which is untested.

#include <MySensor.h>
#include <SPI.h>
#include <DallasTemperature.h>
#include <OneWire.h>

//myPins
const int PIR_PIN = 3;
const int INTERRUPT = 1;
const int DALLAS_PIN = 4;

//myDevices
const int PIR_SENSOR = 1;
const int DALLAS_SENSOR = 2;

OneWire oneWire(DALLAS_SENSOR);
DallasTemperature DallasSensors(&oneWire);

int lastTemperature = -99;
unsigned long readTempInterval = 60 * 60 * 1000UL;  // One Hour Sleep time between reports (in milliseconds)
unsigned long sleepTime = readTempInterval; 
boolean lastTripped = 0;
boolean sendTemp = true;

MySensor gw;

MyMessage motionMsg(PIR_SENSOR, V_TRIPPED);
MyMessage tempMsg(DALLAS_SENSOR, V_TEMP);

void setup()
{
  DallasSensors.begin();
  //DallasSensors.setWaitForConversion(false);  /I could not get this to compile
  gw.begin();
  gw.sendSketchInfo("Multi-Sensor", "1.0alpha");
  pinMode(PIR_PIN, INPUT);      // sets the motion sensor digital pin as input
  gw.present(PIR_SENSOR, S_MOTION);
  gw.present(DALLAS_SENSOR, S_TEMP);
}

void loop()
{
  //gw.process(); don't need this, it is a one-way device.
  boolean tripped = digitalRead(PIR_PIN);
  if (lastTripped != tripped )
  {
    Serial.println(tripped? "Tripped" : "Not Tripped");
    gw.send(motionMsg.set(tripped)); // Send tripped value to gw
    lastTripped = tripped;
  }
  if (sendTemp)
  {
    DallasSensors.requestTemperatures();
    int tempC = (int) DallasSensors.getTempCByIndex(1);
    gw.send(tempMsg.set(tempC));
    lastTemperature = tempC;
    sendTemp = false;
  }
  unsigned long startSleepTime = millis();
  gw.sleep(INTERRUPT, CHANGE, sleepTime);
  unsigned long endSleepTime = millis();
  if (endSleepTime - startSleepTime >= sleepTime)
  {
    sleepTime = readTempInterval;
    sendTemp = true;
  }
  else
  {
    sleepTime = max(sleepTime -= (endSleepTime - startSleepTime), 1000UL);
  }
}

It will send temp to controller once an hour... you can change that for testing;

also will detect motion...

it may need debouncing.

@BulldogLowell Thanks, I'll try it tonight once I get home.

@BulldogLowell I just managed to test this and I have some questions :

1. Motion doesn't seem to work that great - meaning that it takes at least one minute after being untripped to be tripped again
2. Door/window doesn't seem to work - I think I have to add this part, but I'm a bit overwhelmed
3. Temperature starts with temperature of -127C and doesn't update at all (I held my finger on it for 2 minutes) plus I think I need something to avoid -127 temps, like :

if (lastTemperature != tempC && tempC != -127.00)

For your info I used these pins to connect my sensors :

const int PIR_PIN = 3; - PIR sensor
const int INTERRUPT = 4; - Door/Window
const int DALLAS_PIN = 5; - Temperature sensor
[...]
unsigned long readTempInterval = 1 * 60 * 1000UL; - modified read interval to 1 minute for testing purposes

Also I get this output of the serial monitor once I compile and upload the sketch to my nano after 2 minutes and multiple tries to trip PIR sensor :

sensor started, id 2
send: 2-2-0-0 s=255,c=0,t=17,pt=0,l=5,st=ok:1.4.1

send: 2-2-0-0 s=1,c=1,t=16,pt=2,l=2,st=ok:1
Not Tripped

Tripped
send: 2-2-0-0 s=1,c=1,t=16,pt=2,l=2,st=ok:1

I would appreciate any help I can get to get this started... this project has been on hold for at least 1 year and I would like to implement it now since I have all the parts I need, including 5 cases for the motion detectors (I will need to have at least two variations for them). My focus right now is getting a working sketch, with repeating functions or not, I can place repeaters if needed that is not a problem.

[Moshe Livne]

@CaptainZap The motion detector (if you are using one like in the store) has two little dials on it. One is sensitivity and the other is time delay (see http://www.mpja.com/download/31227sc.pdf). Try to play with these until you get the effect you are looking for

[CaptainZap]

@Moshe-Livne That's not the problem... The previous code had the same pir sensor working, it has a couple of seconds timeout.
At this time I'll take another look at my very first sketch, and remove the repeating part, maybe I can get somewhere...
Looking back 1 year ago this was a nice idea, however I've put more time than I would have hoped for into it and I still don't have something that I can call reliable. I know this is a labor of love, and not perfect in any way, I just expected it to be a bit easier to do...

[ThomasDecock]

Did you manage to get this working?
if yes, can you share your script?
I am also having trouble with the dallas temp sensor, if your code works i think it can help me a lot!
(i am trying to make a 'motion - temperature - 3 pwm dimmer' sensor

[CaptainZap]

@ThomasDecock No I wasn't, I was able to get the standard dallas temperature working(because I thought the sensors no longer work), but unfortunately my time on this is pretty limited. I hoped I got it working until I go on vacation, but probably will look into it after.
I would appreciate if someone could help with it, I think everyone would.
