Beehive Monitor, humidity, temp and weight

Hei

I wonder if any body can help me. I have tried, for a while now to make a beehive monitor with arduino but i have chanced to Particle electron. I want to measure temp, humidity and weight in the beehive. I,m using the DHT 22 and the HX711. But i,m struggling to find a code to use with the hardware. I want to publish the result to “Thingspeak”

Can somebody help me ?

the code i tried to use =

#include "ThingSpeak/ThingSpeak.h"
#include "Adafruit_DHT/Adafruit_DHT.h"

// Sensor type
#define DHTTYPE DHT22    	// DHT 22 (AM2302)

// DHT22 sensor pinout:
// Pin 1 (on the left): +3.3V
// Pin 2: output
// Pin 4 (on the right): GROUND
#define DHT_5V_PIN D1
#define DHT_SENSOR_PIN D2
#define DHT_GROUND_PIN D4

DHT dht(DHT_SENSOR_PIN, DHTTYPE);

/* Thingspeak */
TCPClient client;
unsigned long myChannelNumber = 89137;
const char * myWriteAPIKey = "3D23PQHQIJ3OZXNF";

void setup() {
    // Connect to ThingSpeak
    ThingSpeak.begin(client);

    // Give power to the sensor
    pinMode(DHT_5V_PIN, OUTPUT);
    pinMode(DHT_GROUND_PIN, OUTPUT);
    digitalWrite(DHT_5V_PIN, HIGH);
    digitalWrite(DHT_GROUND_PIN, LOW);

    // Wait for the sensor to stabilize
    delay(1000);

    // Initialize sensor
    dht.begin();

    // Read Sensor
    double temperature = dht.getTempCelcius();
    double humidity = dht.getHumidity();

    // Update the 2 ThingSpeak fields with the new data
    ThingSpeak.setField(1, (float)temperature);
    ThingSpeak.setField(2, (float)humidity);

    // Write the fields that you've set all at once.
    ThingSpeak.writeFields(myChannelNumber, myWriteAPIKey);

    // Give time for the message to reach ThingSpeak
    delay(5000);

    // Sleep for 15 minutes to save battery
    System.sleep(SLEEP_MODE_DEEP, 15 * 60);
}

void loop() {
    // This will run because the system is sleeping
}

I have helped build a beehive monitor and I used these two libraries to talk to the sensors
https://build.particle.io/libs/HX711ADC/0.0.2
https://build.particle.io/libs/PietteTech_DHT/0.0.5

I have not used ThingSpeak, so I won’t be a lot of help.

But in order go get help, you may need to be a bit more precise what exactly your are struggling with.
You got some code for the DHT22, but does it work, what do you expect, what do you get, … ?

Hei, and thanks

I,m strugling to include the readings from the hx711. The code for the dht22 works with thingspeak.

My question is… what code is missing or what do i have to add to include the readings from the hx711 and Publishing this on thingspeak…

Have you had a look at the demo that comes with the library?
