A simple strategy to automatically control the speed of fan using DHT22 sensor. According to the temperature sensed by temperature and humidity sensor the resistance of the fan will be adjusted to change the fan
if ((Measured_temp <= (Desired_temperature-3)) && AC == true) //If AC is turned on and temperature is less than 3 degree of Desired value #24 turn off { irsend.sendRaw(ACoff, sizeof(ACoff) / sizeof(ACoff[0]), khz); delay(2000);//Send signal to Turn Off the AC AC_Temp...
This is a library for the BME280 humidity, temperature & pressure sensor Designed specifically to work with the Adafruit BME280 Breakout ---> http://www.adafruit.com/products/2650 These sensors use I2C or SPI to communicate, 2 or 4 pins are required to interface. The device's I2C address...
