Hi All
Yes another beehive monitor.
I'm working through my project in line with my skill level and as I learn new things I will add to the project.
Currently I have 2 DS18B20 sensors reading the "Brood" and "Super" temperature and a DHT22 reading the roof temp and humidity.
It appears in my code that the Brood box is being read, then the DHT22 doing the roof temp and humidity, then the Super is being read, then the DHT22 again. See the serial monitor pic below.
I have searched around and been able to get the code working after a few months of slow learning. I have joined, changed and learnt code so pretty happy with my progress so far.But I cant figure this little one out so your help is appreciated.
[code]
#include <OneWire.h>
#include <DallasTemperature.h>
#include <dht.h>
#define dataPin 8 // Defines pin number to which the sensor is connected
dht DHT; // Creats a DHT object
// Data wire is plugged into port 2 on the Arduino
#define ONE_WIRE_BUS 2
// Setup a oneWire instance to communicate with any OneWire devices
OneWire oneWire(ONE_WIRE_BUS);
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
// Addresses of 3 DS18B20s
uint8_t sensor1[8] = { 0x28, 0x6A, 0x48, 0x7C, 0x0C, 0x00, 0x00, 0xC4 };
uint8_t sensor2[8] = { 0x28, 0xFA, 0x14, 0x7B, 0x0C, 0x00, 0x00, 0x47 };
//uint8_t sensor3[8] = { 0x28, 0x61, 0x64, 0x12, 0x3F, 0xFD, 0x80, 0xC6 };
void setup(void)
{
Serial.begin(9600);
sensors.begin();
}
void loop(void)
{
sensors.requestTemperatures();
Serial.print("Brood Box: ");
printTemperature(sensor1);
Serial.print("Flow Super: ");
printTemperature(sensor2);
//Serial.print("Sensor 3: ");
// printTemperature(sensor3);
Serial.println();
delay(1000);
}
void printTemperature(DeviceAddress deviceAddress)
{
float tempC = sensors.getTempC(deviceAddress);
Serial.print(tempC);
Serial.write(0xC2);
Serial.write(0xBA);
Serial.print("C ");
//Serial.print(DallasTemperature::toFahrenheit(tempC));
//Serial.print((char)176);
//Serial.println("F");
//Uncomment whatever type you're using!
int readData = DHT.read22(dataPin); // DHT22/AM2302
//int readData = DHT.read11(dataPin); // DHT11
float t = DHT.temperature; // Gets the values of the temperature
float h = DHT.humidity; // Gets the values of the humidity
// Printing the results on the serial monitor
Serial.print("Temperature Roof Cavity = ");
Serial.print(t);
Serial.print(" ");
Serial.write(0xC2);
Serial.write(0xBA);//Serial.print((char)176);//shows degrees character
Serial.print("C ");
//Serial.print((t * 9.0) / 5.0 + 32.0);//print the temperature in Fahrenheit
//Serial.print(" ");
//Serial.print((char)176);//shows degrees character
//Serial.println("F ");
Serial.print("Humidity Roof Cavity = ");
Serial.print(h);
Serial.println(" % ");
Serial.println("");
// delay(1000); // Delays 10 seconds
}
