Air Velocity Sensor Arduino

Arduino uno or similar such as the new arduino 101 or genuino 28 or 40 cheaper clones are available arduino 16 2 lcd screen with keypad 2 50 or 3 60 15m of 3 core cable.

Air velocity sensor arduino.

The new sensor works fine for only a few days and then starts reading almost no flow. Were are also using the l9110 motor driver to control the speed and direction of the geared dc motor. It can be changed if necessary. These devices are used in an air scrubber application exhaust stack.

Velocity in x will be itself plus acceleration very small time interval velocityx x float elapsedtime 1000. When the acceleration is zero the velocity will be itself plus zero will not change. Since we will be using interrupt zero to read the speed sensor we need to connect it to pin 2 interrupt 0 pin on the uno. Air flow sensor arduino interfacing.

The red pin can be connected on 5 and the black pin on gnd on arduino board. Hall sensor consumes only 15 20ma which safe to be powered directly from arduino. Arduino air velocity sensor. This sensor can sense hurricane force winds without saturating.

The lcd is connected on pin 5 10 on arduino board. The velocity is an accumulator every iteration it is being added a small velocity component into the velocity accumulator. Sid on ac to dc 12v regulated power supply. Sure you could add a pressure sensor and use the usually existing air temp sensor to predict air mass from velocity but the maf gives a single sensor solution.

It can sens from 0 to 150mph winds and gives output sense voltage upto 3. Arduino code velocity implementation. Thank the fsm maf sensors have. Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor.

The speed sensor uses only 1 pin that goes from low to high to detect holes in the encoder disc. Arduino air flow rate and air pressure sensor bmp180 home made flow meter sensor. Where r is the reading from the arduino analog pin ρ is the density of the fluid air in this case and 2 10 1 is the 10 bit resolution of the arduino s adc there s a 1 because we include 0. This sensor named as read more.

This sensor named as wind sensor rev p and it has hardware compensation for ambient temperature and stand for positive temperature co efficient thermistors.
