The country of Indonesia has a tropical climate. During the dry season there will be more hot conditions. For the middle class, the use of fans is needed as a neutralizer for hot temperatures. Currently the fan is still manually adjusted to the desired speed. Manually setting conditions, of course, cannot adjust to the current temperature conditions. Therefore we need a fan speed control device using a DS18B20 temperature sensor and a PING sensor. In this study, the algorithm system used is the fuzzy logic controller. The results showed that the change in the range of each increase in temperature and distance was linear. The results of the study show that with a temperature are 32 degrees of Celsius and a distance of 18 cm it produces an output of 60. Input temperatures are 35 degrees of Celsius and 16 cm produce an output of 125. Input temperatures are 35 degrees of Celsius and distance of 20 produce an output of 127. Input temperatures are 75 degrees of Celsius and a distance of 35 cm produces an output of 255 and when the temperature reaches 90 degrees of Celsius and a distance of 4 cm, the PWM returns to zerro because the temperature value exceeds the predetermined range.
