Which module I need extra for connection via 4G

Hello

I want to place the sensor, where I do not have a WiFi connection (street lamp pole). Which module with WiFi-Hotspot will be good for connect via 4G? How high will be the monthly traffic?

Thank you and best regards
Paddy

Welcome!
I have never had good experience with such hotspot. We can’t guaranty it will work directly. Maybe you could programm something with a NB-IOT module.
You can calculate the size of the payload:

  "id": 6489703325,
  "timestamp": "2021-08-14 16:09:32",
  "sampling_rate": null,

    "id": 489,
    "sensor_type": {
      "id": 14,
      "name": "SDS011",
      "manufacturer": "Nova Fitness"
    },
    "pin": "1"
  },

    },
    {
      "id": 14216406074,
      "value_type": "P2",
      "value": "8.70"
    }
  ],
  "location": {
    "longitude": "11.576",

    "exact_location": 0,
    "altitude": "516.9"
  }
}

2 times every 145 secondes because madavi and SC.

Thank you for your fast response :slightly_smiling_face:
