Installation

> git clone https://github.com/GreenPonik/GreenPonik_Atlas_Scientific_OEM_i2c.git
cd GreenPonik_Atlas_Scientific_OEM_i2c
pip3 install -r requirements.txt

or

> pip3 install greenponik-atlas-scientific-oem-i2c

from GreenPonik_Altas_Scientific_i2c.ECI2c import ECI2c
from GreenPonik_Altas_Scientific_i2c.PHI2c import PHI2c

Examples

Read EC

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

from GreenPonik_Altas_Scientific_OEM_i2c.ECI2c import ECI2c

if __name__ == "__main__":
    try:
        print("get device infos")
        ec_i2c = ECI2c(
            bus=1,
            addr=ECI2c.ADDR_OEM_TXT_TO_HEXA['EC'],
            moduletype="EC",
        )
        print(ec_i2c.get_device_info())
        # 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)

go to ec example

Read pH

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

from GreenPonik_Altas_Scientific_OEM_i2c.PHI2c import PHI2c

if __name__ == "__main__":
    try:
        print("get device infos")
        ph_i2c = PHI2c(
            bus=1,
            address=PHI2c.ADDR_OEM_TXT_TO_HEXA['PH'],
            moduletype="PH",
        )
        print(ph_i2c.get_device_info())
        print(ph_i2c.get_read())
    except Exception as e:
        print("Exception occured", e)

go to ph example

todo list

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