Make a ESP32 Gateway connect to MQTT an broker with message persistence and a SQL database to store the data. This Project is a simple end-to-end IoT Project by leveraging a NORVII microcontroller ...

I needed a gateway that does not depend on a reliable WiFi connection, so Ethernet was the only option. The MySensors website has instructions for how to build an Ethernet-based gateway (with an ...

The IBM PC spawned the basic architecture that grew into the dominant Wintel platform we know today. Once heavy, cumbersome and power thirsty, it’s a machine that you can now emulate on a single board ...

In theory, using MicroPython on the ESP32 is easy — just flash an image and connect using a serial port. But that leaves a lot of things you still have to do. You need to move files between the two ...

Abstract: The design and implementation of a smart home monitoring system using LoRa and a Heltec ESP32 gateway are presented in this paper. The suggested system uses several LoRa-based sensors ...

Let's take a modular approach to sensor testing. The Sensor Evaluation Board was created to solve the hassle of repeatedly swapping sensors during development. Based on the ESP32-S3, it includes two ...
