cd GreenPonik_Atlas_Scientific_i2c
pip3 install -r requirements.txt
or
> pip3 install greenponik-atlas-scientific-i2cfrom GreenPonik_Altas_Scientific_i2c.GreenPonik_Altas_Scientific_i2c import (

)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)go to ec example
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)go to ph example
todo list
- add calibration workflow in examples
- add compatibility with all circuits (OD / ORP / CO2 / PRESSURE / FLOW)
