RANCANG BANGUN PENGATURAN KECEPATAN PUTARAN KIPAS ANGIN DENGAN MENGGUNAKAN SENSOR SUHU LM35DZ

The fan automatically using temperature sensors is a rotating fan is automatically controlled by the temperature of the room. Fan rotation is adjusted to the predetermined temperature. Systems of this tool consists of hardware, namely AC motors, DC motor driver IC circuit LM358N and sensor circuit LM35DZ. The workings of the system is the sensor detects temperature then comparator receives from the sensor data whether hot or cold temperatures, these data will enable the components of an NPN transistor which causes the fan spins at the time above the temperature setting and will enable the PNP transistor will cause the fan stop at below that temperature setting
