Air Velocity Sensor Arduino

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 velocity sensor arduino.

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. 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. It can be changed if necessary.

The lcd is connected on pin 5 10 on arduino board. 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. Hall sensor consumes only 15 20ma which safe to be powered directly from arduino. Were are also using the l9110 motor driver to control the speed and direction of the geared dc motor.

The new sensor works fine for only a few days and then starts reading almost no flow. 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. 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. This sensor named as read more.

Sid on ac to dc 12v regulated power supply. Arduino code velocity implementation. Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor. Thank the fsm maf sensors have.

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. Arduino air flow rate and air pressure sensor bmp180 home made flow meter sensor. The red pin can be connected on 5 and the black pin on gnd on arduino board.

We have recently replaced a dwyer air velocity transmitter pfs1300204 with a dwyer series 641. When the acceleration is zero the velocity will be itself plus zero will not change. Air flow sensor arduino interfacing. Anemometer sensor or air flow sensor from moderndevice is a low cost arduino friendly air flow sensor.

These devices are used in an air scrubber application exhaust stack.
