Hello,
Firstly, I would like to thank you for working on GMC devices.
I am logging data from a GMC-320S via serial console and I fetch CPM without problem. Data is logged to MQTT and this works like a charm.
Now I would like to calculate ACPM and uSv/h before submitting to GMC World Map. How to calculate ACPM (how many CPM values need to be taken into account) and how to convert CPM to uSv/h?
Kind regards,

Finally I took one day history for ACPM calculation which seams enough. Thanks. |

As I am running Home Assistant I receive a CPM every minute. So I only need to calculte the ACPM sum divided by the number of minutes recorded (which is my number of records). |

All time that it is on. ACPM is calculated every second.
acpm = total_count/(elapsed_second_total/60.0); |

Thank you for the answer. How many records are taken into account by the GMC-320 device? |

You can decide how many records do you want for ACPM. |

Okay, I reply to myself, this is calculated to be 154 CPM for 1 uSv/hr for GMC-320/GMC-320S, right? How many records need to be taken into account for ACPM? |
