This sensor named as wind sensor rev p and it has hardware compensation for ambient temperature and stand for positive temperature co efficient thermistors.
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.
I m building working model of differential pressure airflow measure device with analog sensor instrumentation amplifier and arduino.
Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor.
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.
It can sens from 0 to 150mph winds and gives output sense voltage upto 3.
The design is for an orifice type flow sensor the orifice in our case a washer provides a restriction and.
Below are some photos of the device.
In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow.
For this specific problem we wanted the wind speed in cfm so we displayed it as so on the screen.
The first step in construction is to start with the anemometer.
