This desired value is a constant value which is set as 27°C (Degree Celsius) in my program. To make the project look more attractive and user friendly I have also added an OLED display that display the current Temperature, Humidity and AC set temperature. The block diagram includes power supply, RST circuit, 8051 microcontrollers, LM35 temperature sensor, 8 bit ADC, L293D motor driver, DC motor, 7-segment display, i/p switches. Electronic Thermostat Circuit and Working. You have to change the Signal code values that we just obtained from the Example sketch above. unsigned int Temp24[] = {3000,1650, 500,1050, 500,1000, 500,300, 500,300, 500,350, 500,1000, 500,300, 500,350, 500,1000, 500,1050, 500,300, 500,1000, 500,300, 500,350, 500,1000, 500,1050, 500,300, 500,1000, 500,1050, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,1050, 500,1000, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,1000, 500,1050, 500,1000, 500,300, 500,350, 450,350, 500,300, 500,300, 500,350, 500,1000, 500,300, 500,1050, 500,1000, 500,1050, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,300, 500,350, 500,300, 450,350, 500,350, 450,350, 450,350, 450,350, 450,400, 400,400, 400,400, 450,400, 400,400, 400,400, 400,400, 450,350, 450,400, 400,400, 450,350, 450,400, 450,350, 450,350, 450,350, 450,400, 450,350, 450,350, 450,350, 500,350, 450,1050, 500,300, 500,1050, 500,1000, 500,1050, 500,1000, 500,1000, 500,350, 550};   Can you send me the code for the same (arduino Mega)? As your room’s temperature changes, the Arduino will also adjust your AC’s set temperature to maintain your temperature in just the way you want it to be. The concept of this paper is to create an automatic temperature control system to control the temperature of a system.   display.setTextSize(1); #define OLED_RESET 7 Thank you for explaination about the this project topic Automatic AC temperature controller using arduino, DHT111 and IR blaster. Amplifier circuits. By varying the set temperature periodically we can avoid making the AC to work for lower temperature values for a long time and thus making it consume less power. int Measured_temp;     12  TSOP – Gnd  Gnd You can simply use a breadboard and make the connections as shown below. token. }, if (Measured_temp == 27 ) //If AC is ON and measured temp is desired value The following table can also be used to verify your connections. }, if (Measured_temp == Desired_temperature+2) //If AC is ON and measured temp is very high than desired For every 1°C of rise/fall in temperature, the output voltage of the sensor varies by 10mV. Automatic control plays an ever-increasing role in human way of life.     3 OLED- SCK, D0,SCL,CLK 4   display.print("Humidity: "); display.print(Measured_Humi);display.println("%"); The circuit of automatic temperature controlled fan is build around temperature transducer AD590 followed by operational amplifier LM324.   AC_Temp = 0; AC=false; This temperature controlled fan circuit is highly efficient as it uses thyristors for power control. Place the temperature sensor on … A 9v battery powers the hobby circuit. May be one or two buttons can be remembered.   AC_Temp = 25;    irsend.sendRaw(ACon, sizeof(ACon) / sizeof(ACon[0]), khz); delay(2000); //Send Signal to Turn On the AC    display.setCursor(0,20); Now, here is the circuit of Automatic temperature controlled fan used to control the speed of fan according to change in temperature. display.begin(SSD1306_SWITCHCAPVCC);     11  TSOP – Vcc  5V Figure 1: Automatic Temperature Control Block diagram. Why don't you answer this and explain . This circuit maintains the temperature of the system in a particular range. For example Temp23 is used to set 23°C on your AC, so use the respective code in that Array. Note that I have used 10 Arrays out of which two used to Turn ON and turn OFF the AC while the rest 8 is used to set different temperature. Description. When i press the botton , serial nuber write ; too long raw icrease raw buffer in ir remoteUnt.h I increase it to 255 but not solve and that warnin writed again . To automate this process this project uses a Temperature sensor (DHT11) which reads the present temperature of the room and based on that value it will send commands to the AC through an IR blaster similar to the AC’s Remote. Let’s see how to build one. token, DHT.read11(DHT11_PIN); //Read the Temp and Humidity, __:80: error: expected primary-expression before '.'   irsend.sendRaw(Temp27, sizeof(Temp27) / sizeof(Temp27[0]), khz); //Send signal to set 27*C unsigned int Temp26[] = {3000,1650, 500,1000, 500,1050, 500,300, 500,300, 500,350, 500,1000, 500,300, 500,350, 500,1000, 500,1050, 450,350, 500,1000, 500,300, 500,350, 500,1000, 500,1050, 500,300, 500,1000, 500,1050, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,1050, 500,300, 500,300, 500,1050, 450,350, 500,300, 500,1050, 500,1000, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,1000, 500,300, 500,1050, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,1050, 500,300, 500,1050, 450,1050, 500,1000, 500,350, 500,300, 500,300, 500,350, 450,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 450,350, 500,300, 500,350, 450,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,350, 500,300, 500,300, 500,300, 500,350, 500,300, 500,300, 500,350, 450,1050, 500,1000, 500,350, 500,1000, 500,1000, 500,1050, 500,1000, 500,350, 500};   AC remotes work in a bit different way compared to TV, DVD IR remotes.     14  IR Led – Cathode  Gnd These are more suitable in areas where a precise temperature control may be required.
