Constructor & Destructor Documentation

__init__()

def qwiic_fs3000.QwiicFS3000.__init__	(		self,
			address = None,
			i2c_driver = None
	)

Constructor.

Parameters

int,optional	address: The I2C address to use for the device If not provided, the default address is used
I2CDriver,optional	i2c_driver: An existing i2c driver object If not provided, a driver object is created

Member Function Documentation

begin()

def qwiic_fs3000.QwiicFS3000.begin

(

self

)

Initializes this device with default parameters.

Returns

bool Returns True if successful, otherwise False

checksum()

def qwiic_fs3000.QwiicFS3000.checksum	(		self,
			data_in
	)

CHECKSUM Check to see that the CheckSum is correct, and data is good Return true if all is good, return false if something is off
The entire response from the FS3000 is 5 bytes.

[0]Checksum [1]data high [2]data low [3]generic checksum data [4]generic checksum data

Parameters

list	data_in: The data to check

Returns

bool Returns True if successful, otherwise False

is_connected()

def qwiic_fs3000.QwiicFS3000.is_connected

(

self

)

Determines if this device is connected.

Returns

bool True if connected, otherwise False

read_meters_per_second()

def qwiic_fs3000.QwiicFS3000.read_meters_per_second

(

self

)

Read from sensor, checksum, return m/s (0-7.23)

Returns

float The air velocity value in meters per second (or -1 on error)

read_miles_per_hour()

def qwiic_fs3000.QwiicFS3000.read_miles_per_hour

(

self

)

Read from sensor, checksum, return mph (0-33ish)

Returns

float The air velocity value in miles per hour (or -1 on error)

read_raw()

def qwiic_fs3000.QwiicFS3000.read_raw

(

self

)

Read from sensor, checksum, return raw data (409-3686)

Returns

int The raw value from the sensor (or -1 on error)

set_range()

def qwiic_fs3000.QwiicFS3000.set_range	(		self,
			range
	)

There are two varieties of this sensor (1) FS3000-1005 (0-7.23 m/sec) and (2) FS3000-1015 (0-15 m/sec)

Valid input arguments are: AIRFLOW_RANGE_7_MPS AIRPLOW_RANGE_15_MPS

Note, this also sets the datapoints (from the graphs in the datasheet pages 6 and 7). These datapoints are used to convert from raw values to m/sec - and then mph.

Parameters

int	range: The range of the sensor

Returns

bool Returns True if successful, otherwise False
