Air Velocity Sensor Arduino

It can sens from 0 to 150mph winds and gives output sense voltage upto 3.

Air velocity sensor arduino.

Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor. Hall sensor consumes only 15 20ma which safe to be powered directly from arduino. Thank the fsm maf sensors have. When the acceleration is zero the velocity will be itself plus zero will not change.

The lcd is connected on pin 5 10 on arduino board. 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. Were are also using the l9110 motor driver to control the speed and direction of the geared dc motor. Velocity in x will be itself plus acceleration very small time interval velocityx x float elapsedtime 1000.

After the hardware design is connected as shown in the schematic make sure the sensor is connected. We have recently replaced a dwyer air velocity transmitter pfs1300204 with a dwyer series 641. The velocity is an accumulator every iteration it is being added a small velocity component into the velocity accumulator. The speed sensor uses only 1 pin that goes from low to high to detect holes in the encoder disc.

Sid on ac to dc 12v regulated power supply. This sensor can sense hurricane force winds without saturating. This sensor named as wind sensor rev p and it has hardware compensation for ambient temperature and stand for positive temperature co efficient thermistors. This sensor named as read more.

The red pin can be connected on 5 and the black pin on gnd on arduino board. Air flow sensor arduino interfacing. Arduino air velocity sensor. 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.

It can be changed if necessary. 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. These devices are used in an air scrubber application exhaust stack. Arduino code velocity implementation.

The new sensor works fine for only a few days and then starts reading almost no flow.
