How to make an accurate air flow rate sensor with arduino for under 20 covid 19 ventilator.
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.
This sensor can sense hurricane force winds without saturating.
Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor.
For this specific problem we wanted the wind speed in cfm so we displayed it as so on the screen.
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.
Below are some photos of the device.
The first step in construction is to start with the anemometer.
It can sens from 0 to 150mph winds and gives output sense voltage upto 3.
I m building working model of differential pressure airflow measure device with analog sensor instrumentation amplifier and arduino.
