Humidity and temps not showing in console

[randycool279]

Hey. I’m trying to get my Tracker SoM to publish humidity and temp data to the particle console using this code:

#include "Particle.h"

#include "tracker_config.h"
#include "tracker.h"

#include "./lib/Grove_Temperature_And_Humidity_Sensor/src/Grove_Temperature_And_Humidity_Sensor.h"
#include "./lib/TemperatureHumidityValidatorRK/src/TemperatureHumidityValidatorRK.h"

SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(SEMI_AUTOMATIC);

PRODUCT_ID(TRACKER_PRODUCT_ID);
PRODUCT_VERSION(TRACKER_PRODUCT_VERSION);

SerialLogHandler logHandler(115200, LOG_LEVEL_TRACE, {
    { "app.gps.nmea", LOG_LEVEL_INFO },
    { "app.gps.ubx",  LOG_LEVEL_INFO },
    { "ncp.at", LOG_LEVEL_INFO },
    { "net.ppp.client", LOG_LEVEL_INFO },
});

DHT tempSensor(A3);

TemperatureHumidityValidator validator;

// Sample the temperature sensor every 2 seconds. This is done so the outlier values can be filtered out easily.
const unsigned long CHECK_PERIOD_MS = 2000;
unsigned long lastCheck = 0;

void locationGenerationCallback(JSONWriter &writer, LocationPoint &point, const void *context); // Forward declaration

void setup()
{
    Tracker::instance().init();

    // Callback to add key press information to the location publish
    Tracker::instance().location.regLocGenCallback(locationGenerationCallback);

    // Initialize temperature sensor
    tempSensor.begin();

    Particle.connect();
}

void loop()
{
    Tracker::instance().loop();

    if (millis() - lastCheck >= CHECK_PERIOD_MS) {
        lastCheck = millis();

        validator.addSample(tempSensor.getTempCelcius(), tempSensor.getHumidity());

        Log.info("tempC=%f tempF=%f humidity=%f", validator.getTemperatureC(), validator.getTemperatureF(), validator.getHumidity());
    }
}


void locationGenerationCallback(JSONWriter &writer, LocationPoint &point, const void *context)
{
    float tempC = validator.getTemperatureC();
    if (!isnan(tempC)) {
        writer.name("temp").value(tempC, 2);
    }

    float hum = validator.getHumidity();
    if (!isnan(hum)) {
        writer.name("hum").value(hum, 1);
    }
}

It compiles fine, but I get no output of Humidity or temps on the console or usb serial output. I’m pretty stumped and any help is appreciated!

Hi @randycool279,

As a start, can you send us a photo of how the sensor is connected? Thank you.

Sure, I’ve attached the photo below. I set the pin to A3 on the code to communicate with the port the sensor is plugged into.

Thanks!
