I am gratefull ;)

I will try to compare the sketches.

@hek But I was hoping to use the DS18b20?

@hek Wow - thanks for a fast reply

I have used a some what similar sketch as a basis and I guess I go wrong when adapting the sketch to the Dallas sensor which I presume is needed?

Hi,

So I am new to building sensors.

I have managed to build a ethernet gateway and have this connect to my Vera2.

Furthermore I have succeeded in building temperature and motion sensors.

So far so good.

Now I want to combine the sensors in a new sensor - a 230V powered motion and temp sensor (based on a Nano-clone)

I have search the forum to see if anyone else has made this kind of sensor (for me to copy the sketch) but with no luck.

I have the tried to combine the temp sketch and the motion sketch from the build-page, into the below sketch but the sketch wont compile. I have no experience in this so my combination is mostly based on gut-feeling :)

Is there any one who can have a look at the sketch and explain where I go wrong or even better - are there anyone with a similar sensor and working sketch that I can use?

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

#define CHILD_ID_MOT 2 // Id of the sensor child
#define ONE_WIRE_BUS 4 // Pin where dallase sensor is connected

#define MAX_ATTACHED_DS18B20 16
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

#define DIGITAL_INPUT_SENSOR 3 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)

MySensor gw;
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors=0;
boolean receivedConfig = false;
boolean metric = true;
// Initialize temperature message
MyMessage msg(0,V_TEMP);

// Initialize motion message
MyMessage msgMot(CHILD_ID_MOT, V_TRIPPED);

void setup()
{
sensors.begin();

gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Motion Sensor", "1.0");

numSensors = sensors.getDeviceCount();

for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
gw.present(i, S_TEMP);

pinMode(DIGITAL_INPUT_SENSOR, INPUT); // sets the motion sensor digital pin as input
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID_MOT, S_MOTION);

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Temperature Sensor", "1.0");

// Fetch the number of attached temperature sensors
numSensors = sensors.getDeviceCount();

// Present all sensors to controller
for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
gw.present(i, S_TEMP);
}
}

void loop()
{

// Read digital motion value
boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH;

Serial.println(tripped);
gw.send(msg.set(tripped?"1":"0")); // Send tripped value to gw

{
// Process incoming messages (like config from server)
gw.process();

// Fetch temperatures from Dallas sensors
sensors.requestTemperatures();

// Read temperatures and send them to controller
for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {

// Fetch and round temperature to one decimal
float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

// Only send data if temperature has changed and no error
if (lastTemperature[i] != temperature && temperature != -127.00) {

  // Send in the new temperature
  gw.send(msg.setSensor(i).set(temperature,1));
  lastTemperature[i]=temperature;
}

}

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

Thanks!
