The cheapest sensors seems to be a car s mass air flow sensor.
Mass air flow sensor arduino.
F1031v mass air flow sensor adopts thermodynamic principle to detect flow rate of gas medium in the flow channel with high precision and good repeatability.
I m wondering if there is a way use one of these maf to measure air flow in liters per minute.
This sensor named as wind sensor rev p and it has hardware compensation for ambient temperature and stand for positive temperature co efficient thermistors.
It s likely that the sensor will run on 12v and output an analog voltage from 0 12 so you might need to use a voltage.
This type of flow sensor is designed to measure the volume of liquid traveling past a given point a great way to keep tabs on how much water your drip irrigation system is using or any other project were the flow of liquid needs to be tracked.
Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor.
It can sens from 0 to 150mph winds and gives output sense voltage upto 3.
In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow.
Meanwhile the sensor has liner analog voltage output easy to use.
It comes with built in temperature sensor to provide temperature compensation for measured data.
There s no reason that an maf couldn t be used with an arduino.
Arduino air flow rate and air pressure sensor bmp180 home made flow meter sensor.
Hot wire automotive mass air flow sensor primary components of a hot wire maf sensor are a thermistor a platinum hot wire and an electronic control circuit.
This sensor can sense hurricane force winds without saturating.
The air flow sensor is located directly in the intake air stream between the air cleaner and throttle body where it can measure incoming air.
