Mar 26, 2018 - Oscar Gonzalez gives us a simple tutorial for speed controlling a PC FAN and reading a LM35 temperature sensor with an Arduino. Learn more about using OLED with Arduino. Pre-requisites: This Automatic AC Temperature Controller project is slightly advanced for beginner’s level, however with help of few other tutorials anyone can build this with matter of time. So if you are a absolute newbie to OLED, DHT11 or TSOP then kindly fall back to these tutorials below where.

This paper presents the designs and the simulation of a DC fan control system based on room temperature using pulse width modulation technique, humidity and temperature sensor namely DHT11 with Arduino Uno Microcontroller. The fan will be used to reduce temperature of a room at certain level. To build the fan, we will use DTH11 Humidity Sensor. The sensor will measure the temperature continuously. When the temperature gets higher from a specific temperature, the fan will be on “On” mode. The speed of the fan will be determined by pwm using pulse-width modulation.

Hi, I followed all the instructions but im having a problem with the irsend, the ir can not opent the AC once reaches above 27C as per your program says: if ((Measured_temp >= Desired_temperature+4) && AC == false) //If AC is off and measured Temp is greater than Desired Temp { irsend.sendRaw(ACon, sizeof(ACon) / sizeof(ACon[0]), khz); delay(2000); //Send Signal to Turn On the AC delay(2000); irsend.sendRaw(Temp27, sizeof(Temp27) / sizeof(Temp27[0]), khz); //Send signal to set 27*C AC_Temp = 27; AC=true; •.
