==Objective==
To control air conditioner by detecting environment temperature. When temperature increases to a certain value, the air conditioner will start. On the contrary, the air conditioner will close when the outside temperature decreases to a certain value.

==Principle==
Use temperature and humidity sensor AM2321 to detect indoor temperature and then control the air conditioner by matching codes with infrared transmission sensor.

==Hardware Buildup==
*Setup 1: Stack CoreUSB and Sensorhub.
[[File:CoreUSB_Ble_Sensorhub.jpg|600px|center|thumb]]
*Setup 2：Connect Microduino-IR transmitter via pin board to D3 pin of Sensorhub and Microduino-Temp&Hum to IIC pin of Sensorhub.

==Software Debugging==
*Air conditioner infrared remote control encoding definition. Here the conditioner adopts NEC encoding format.
<source lang="cpp">
IRsend irsend; //Infrared transmission
AM2321 am2321; //Temperature and humidity sensor AM2321

#define POWER_ON 0xC1602680 //Air conditioner power on/off encoding
float temp = 0; //Temperature value
unsigned long runTime = 0; //Air conditioner power on/off time

</source>

*Detect the current temperature value every second. When the temperature is above 30℃, the air conditioner opens and when it is below 25℃, the air conditioner closes. The time interval between opening and closing is 180s for fear of frequent operation.
<source lang="cpp">
am2321.read(); //Acquire the current temperature value
temp = am2321.temperature/10.0;
if(millis()>runTime+180000) //Above 180s time interval
{
if(temp > 30) //Higher than 30℃ and the air conditioner opens.

{
irsend.sendNEC(0xC1602680,32);
irsend.sendCode(0x00000000,16);
runTime = millis();
}
else if(temp <25) //Lower than 30℃ and the air conditioner closes.
{
irsend.sendNEC(0xC1602680,32);
irsend.sendCode(0x00000000,16);
runTime = millis();
}
}
delay(1000);

</source>

==Program==
[[https://github.com/Microduino/Microduino_Tutorials/tree/master/MCookie_Tutorial/MicroduinoAirConditioner MicroduinoAirConditioner]]

==Result==
When the temperature is above 30℃, the air conditioner opens and when it is below 25℃, the air conditioner closes. By detecting temperature value to control other functions of the air conditioner.
