Examples

Read EC

works with EC circuit https://www.atlas-scientific.com/circuits/conductivity-oem-circuit/

from GreenPonik_Altas_Scientific_i2c.GreenPonik_AltasI2c import AtlasI2c
from GreenPonik_Altas_Scientific_i2c.GreenPonik_ECI2c import ECI2c

if __name__ == "__main__":
    try:
        print("get device infos")
        i2c_device = AtlasI2c(
            address=AtlasI2c.ADDR_EZO_TXT_TO_HEXA['EC'],
            moduletype="EC",
            name="EC"
        )
        ec_i2c = ECI2c(i2c_device)
        print(ec_i2c.get_device_info())
        print("get current temperature compensated")
        print(ec_i2c.get_temperature())
        # put here the current temperature
        print(ec_i2c.set_temperature(25.00))
        ec = ec_i2c.get_read()
        print("current ec is %.2f" % ec)
    except Exception as e:
        print("Exception occured", e)

Read pH

works with pH circuit https://www.atlas-scientific.com/circuits/ph-oem-circuit/

from GreenPonik_Altas_Scientific_i2c.GreenPonik_AltasI2c import AtlasI2c
from GreenPonik_Altas_Scientific_i2c.GreenPonik_PHI2c import PHI2c

if __name__ == "__main__":
    try:
        print("get device infos")
        i2c_device = AtlasI2c(
            address=AtlasI2c.ADDR_EZO_TXT_TO_HEXA['PH'],
            moduletype="PH",
            name="PH"
        )
        ph_i2c = PHI2c(i2c_device)
        print(ph_i2c.get_device_info())
        print(ph_i2c.get_read())
    except Exception as e:
        print("Exception occured", e)

todo list

• add calibration workflow in examples
• add compatibility with all circuits (OD / ORP / CO2 / PRESSURE / FLOW)
