Electrical Engineering World Automatic Fan Controller Circuit 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. To install a fan controller, first, shut down your computer and disconnect the power supply. then, open your computer case and locate an available drive bay. insert the fan controller into the drive bay and secure it using the screws provided. connect the fans to the fan controller using the appropriate cables.
Automatic Fan Controller Circuit Electronic Circuits Diagram Working of automatic temperature controlled fan using thermistor. it works on the principle of thermistor. in this circuit, pin 3 (non inverting terminal of op amp 741) is connected with the potentiometer and pin 2 (inverting terminal) is connected in between of r2 and rt1 (thermistor) which is making a voltage divider circuit. 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. Part list of automatic fan controller : ic lm35, any general purpose npn transistor eg bc548, bc187 etc. low power dc motor you can easily get from old thrown dvd player or tape recorder, small fan blade, 10 ohms or 4.7 ohms resistance, battery etc. if you are using other npn transistor, which is not mentioned above then please make sure of pin. Figure 2 shows the differences between 3 wire and 4 wire fan circuits. figure 2. 3 and 4 wire fans. fan control. no control: the simplest method of fan control is not to use any at all; just run a fan of appropriate capacity at full speed 100% of the time. the main advantages of this are guaranteed fail safe cooling and a very simple external.
