Temperature Based Automatic Fan Speed Controller Using Arduino Automatic temperature controlled fan project using arduino. in this arduino based project, we are going to build a temperature controlled fan using arduino. with this circuit, we will be able to adjust the fan speed in our home or office according to the room temperature and also show the temperature and fan speed changes on a 16x2 lcd display. The threshold level of the automatic fan controller is made with a thermometer. place the sensor on the surface which temperature you want to monitor. read the temperature with the thermometer and adjust the threshold level of the fan with p1 at the desired temperature. the second comparator goes from low to high state when the threshold level.
Automatic Fan Control Readme Md At Master Leductan Nguyen Automatic Fan Control Github Fan starts automatically, so it can control the temperature manually. automatic switching will save the energy. for cooling heat dissipating devices, installation is easy. applications of temperature controlled dc fan. cooling fans for laptops and computers. this device is used for cooling the car engine. Working of the temperature based fan speed controller circuit. lm35 temperature sensor senses the temperature and send the analog signal to arduino, then arduino converts the analog signal to digital signal and display the value on lcd display and calculate the percentage of speed the fan should be spinned. the calculated percentage is sent to. This standalone automated fan speed controller project changes the fan’s speed by utilizing feedback in real time. effective and reliable temperature control is accomplished by using embedded system technologies like a microcontroller and closed loop control architecture. the atmega8 168 328 microcontroller allows for rapid adjustments to fan. Circuit diagram of the temperature based fan speed control & monitoring with arduino & lm35 is shown above. arduino is at the heart of the circuit as it controls all functions. lm35 is a precision integrated circuit whose output voltage is linearly proportional to celsius (centigrade) temperature. it is rated to operate over a 55°c to 150°c.
