Air Flow Sensor Arduino

Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor.

Air flow sensor arduino.

For this specific problem we wanted the wind speed in cfm so we displayed it as so on the screen. This instructables shows how to build an air flow rate sensor using a low cost differential pressure sensor and readily available materials. The design is for an orifice type flow sensor the orifice in our case a washer provides a restriction and. In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow.

I m building working model of differential pressure airflow measure device with analog sensor instrumentation amplifier and arduino. This sensor can sense hurricane force winds without saturating. It can sens from 0 to 150mph winds and gives output sense voltage upto 3. An arduino uno was used to read the analog signal from the voltage sensor and control what was presented on the lcd screen.

Below are some photos of the device. This sensor named as wind sensor rev p and it has hardware compensation for ambient temperature and stand for positive temperature co efficient thermistors.
