Ich habe eine große Datenmenge in einer Sammlung in Mongodb, die ich analysieren muss. Wie importiere ich diese Daten zu Pandas?

Ich bin neu für Pandas und Taubheitsgefühle.

BEARBEITEN: Die Mongodb-Sammlung enthält Sensorwerte mit Datum und Uhrzeit. Die Sensorwerte sind vom Datentyp float.

Beispieldaten:

"_cls" : "SensorReport",
"_id" : ObjectId("515a963b78f6a035d9fa531b"),
"_types" : [
    "SensorReport"
],
"Readings" : [
