# Installation

```shell

> git clone https://github.com/GreenPonik/GreenPonik_Atlas_Scientific_i2c.git

cd GreenPonik_Atlas_Scientific_i2c

pip3 install -r requirements.txt

or

> pip3 install greenponik-atlas-scientific-i2c

```

```python

from GreenPonik_Altas_Scientific_i2c.GreenPonik_Altas_Scientific_i2c import (

    AtlasI2c,

    ECI2c,

    PHI2c,

)

```

# Examples

## **Read EC**

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


```python

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)

```

go to [ec example](examples/read_ec.py)

## **Read pH**

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


```python

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)

```

go to [ph example](examples/read_ph.py)

## todo list

- add calibration workflow in examples

- add compatibility with all circuits (OD / ORP / CO2 / PRESSURE / FLOW)
