Air Flow Sensor Arduino

The first step in construction is to start with the anemometer.

Air flow sensor arduino.

This instructables shows how to build an air flow rate sensor using a low cost differential pressure sensor and readily available materials. Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor. This sensor can sense hurricane force winds without saturating. I m building working model of differential pressure airflow measure device with analog sensor instrumentation amplifier and arduino.

Below are some photos of the device. For this specific problem we wanted the wind speed in cfm so we displayed it as so on the screen. How to make an accurate air flow rate sensor with arduino for under 20 covid 19 ventilator. This sensor named as wind sensor rev p and it has hardware compensation for ambient temperature and stand for positive temperature co efficient thermistors.

An arduino uno was used to read the analog signal from the voltage sensor and control what was presented on the lcd screen. It can sens from 0 to 150mph winds and gives output sense voltage upto 3.
