Arduino Data Logger using MongoDB Database

This post will show you how you can create your own Arduino Data Logger application that will save temperature readings to your MongoDB database. I have used an ESP32 microcontroller board in interfacing with my DHT22/DHT11 sensors. The REST API Server is built using Python, Flask, and PyMongo.

Hi, is there a way to put serial data from COM into MongoDB? I'm using Arduino Uno connected with PC via USB. I've built a weather station with couple of sensors and want to send sensor readings to MongoDB.

what is the benefit using http method compared to mqtt method?
