| This simple circuit uses an incandescent lamp to detect airflow. With the filament exposed to air, a constant current source is used to slightly heat the filament. As it is heated, the resistance increases. As air flows over the filament it cools down, thus lowering it's resistance. A comparator is used to detect this difference and light an LED. With a few changes, the circuit can be connected to a meter or ADC to provide an estimation on the amount of air flow. |

| i think it will not work properly | ||
| Can some one tell me about R4?... is it a varible resistor or a fixed resistor??.... I have built this circuit many of times but have not been able to get it to work..... Can anyone give me some feedback...thanks!! | ||
| sir i am going to take this as my project of present semster can i have some more details about this???? plz plz plz | ||
| hi there. nice circuit. i have some problems regarding the Incandescent lamp. i would like to implement this circuit into the pspice program but i do have problem to place the incandescent lamp. may i know, if there is a part can replace the criteria of the incandescent lamp in pspice? thank you | ||
| Sir i want to take this circiut as my annual project,so plz plz send me more details about this cct. | ||
| Hello friends, I can make an alarm for the fan of the motor of a car. When for of ventilating the detector it had informed me. | ||
| I haven't built one yet but I will try next week and let you know how good it is. I will have to trace the bulb first and may take me some time. | ||
| A practical use of this? This is how a Mass Airflow Sensor works in late model cars. The computer must know how much air is flowing into the intake manifold so the computer can keep the air/fuel mixture at 14.7:1 (at sea level). By keeping a voltage constant through a wire in the MAS, the current can be measured to determine the airflow. | ||
| I would like to know the working of air flow detector and component description. | ||
| Hai . I am Baist . I am making aproject plz give me some other simple progect , | ||
