malc-lib

DHT Temperature & Humidity Sensor and Relay Control library for Arduino

İncluding Libray and Create Object

#include <malc.h>
malc MALC;

Setting Relay and DHT 11 Pins

int relay_pins[4]={2,3,4,5};
MALC.set_relay_pins(relay_pins ,relay_pins.lenght);
int DHT_MODEL = 11;
int DHT_PIN = 7;
MALC.set_dht_pin(DHT_PIN ,DHT_MODEL);

Open and Close One Relay
When open a one relay write to EEPROM.
EEPROM address equals to relay_pin array index number.

MALC.open_relay(int relay_pin_number);
MALC.close_relay(int relay_pin_number);

Open and Close All Relays

MALC.open_all_relays();
MALC.close_all_relays();

Reading Humidity and Temperature

MALC.read_dht();
double temperature = MALC.temperature;
double humidity = MALC.humidity;

Getting Relay Status

When after reboot or shutdown save to EEPROM relay status automatically.
In this way get last opened relays and open last relays.
This code writing to setup() function.

for (int i = 0; i < relay_pins.length; i++)
{
  if (MALC.get_last_open_relay_after_reboot(i)==1) MALC.open_relay(relay_pins[i]);
}

Relay pins setter method

int malc::set_relay_pins(int relays[] ,int size){
	
	RELAY_COUNTER = size;
	
	for (int i = 0; i < RELAY_COUNTER; i++)
	{
		relay_pins[i] = relays[i];
		pinMode(relay_pins[i] ,OUTPUT);
	}
	
	// WHEN RELAY SET AGAIN CLOSE ALL RELAYS
	for (int i = 0; i < RELAY_COUNTER; i++)
		{
			digitalWrite(relay_pins[i],HIGH);
		}
	return 0;
}
