Example Usage

from loadstar_sensors_interface import LoadstarSensorsInterface
dev = LoadstarSensorsInterface() # Try to automatically detect port
dev = LoadstarSensorsInterface(port='/dev/ttyUSB0') # Linux specific port
dev = LoadstarSensorsInterface(port='/dev/tty.usbmodem262471') # Mac OS X specific port
dev = LoadstarSensorsInterface(port='COM3') # Windows specific port

dev.tare()
sensor_value = dev.get_sensor_value()

model = dev.get_model()
device_id = dev.get_device_id()
units = dev.get_units()
load_capactiy = dev.get_load_capacity()
dev.set_averaging_window(10) # 1-1024 samples
dev.set_averaging_threshold(10) # 1-100 percent

dev.set_scale_factor(453.59) # e.g. lb to gram
scale_factor = dev.get_scale_factor()

settings = dev.get_settings()
