Temperature Sensor problem

tbowmo

Have you set the correct board type in arduino? Could look like the baudrate doesn't match..

BulldogLowell

it could also be as simple as the sketch in the library does not by default enable serial communication, nor does that sketch output any Serial data!!

try inserting the lines I added below and make sure that your baudrate on your serial Monitor is the same (115200bps)

void setup()  
{ 
  Serial.begin(115200);  //<<<<<<<<<<<<<<<<<<<<<  Add This Line
  // Startup OneWire 
  sensors.begin();

  // Startup and initialize MySensors library. Set callback for incoming messages. 
  gw.begin(); 

  // 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);
  }
  Serial.println("Yeah!! now it works!!");
}

Entire library sketch:

// Example sketch showing how to send in OneWire temperature readings
#include <MySensor.h>  
#include <SPI.h>
#include <DallasTemperature.h>
#include <OneWire.h>

#define ONE_WIRE_BUS 3 // 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);
MySensor gw;
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors=0;
boolean receivedConfig = false;
boolean metric = true; 
// Initialize temperature message
MyMessage msg(0,V_TEMP);

void setup()  
{ 
  // Startup OneWire 
  sensors.begin();

  // Startup and initialize MySensors library. Set callback for incoming messages. 
  gw.begin(); 

  // 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()     
{     
  // 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;
    }
  }
  gw.sleep(SLEEP_TIME);
}

Yep I agree, looks like wrong baudrate.

"Check wires" error when you don't have the NRF radio connected properly.

vampircik

I connected properly checked.

sundberg84

I have seen "check wires" a 100 times and every time it is because I missed in the wiring.

Double and tripple check wiring in both arduino and radio side.
If its correct, try another radio, change wires or even try another arduino.

Good luck.

hek

And make sure you haven't enabled SOFTSPI earlier and forgot to change it back.

vinzouille

Hi,

I had the check wires problem and this topic was helpful thanks a lot :)
Now I don't have this error message anymore but I don't have any message at all, so my question is am I supposed to have any message while running my temperature sensor on serial monitor ?

vinzouille

I found the solution this was my NRF that didn't work
