What velocity of air flow are you wanting to measure? HVAC? Wind? Breath?I need any air flow measurement sensor/circuit so i could measure the amount air is flow.
I searched on google but i got air flow detector using opamp but i need measurement of air flow.
Absolutely the best way to measure airflow in an engine is to use a second MAF (Mass airflow meter) as a MAF will give you a far more accurate and linear output than any alternative. Automotive MAFs have specially circuitary built in to compensate for changes in density and are designed to be linear for the kind of air flow ranges in an engine.There are two main typesMass Airflow Meter from a car ? Sorry, im a mechanic by trade.
