This project implements an ESP32-based TCP server with RFID authentication using the RC522 RFID reader. The ESP32 connects to a Wi-Fi network, allowing a client to send user credentials (name and ...

This project utilizes an ESP32 microcontroller to interface with an RFID sensor, allowing the system to read RFID tags. The collected data is then sent to Firebase ...

備忘録：Raspberry Piが母機で居た方が都合が良いな… M5Stack⇒PCへ戻す 1.オフラインM5Stack⇒スタンドアロンRaspberry Piへケーブルで通信。 このプログラムはRaspberry Piで実行することになる。 2.吸い込んだデータをRaspberry Piが集約して、 PythonでQRコードにして ...

Abstract: This work has the purpose of presenting the expansion of Arduino Library for PNRD (elementary Petri Net inside RFID distributed Database) and iPNRD (inverted PNRD) to ESP32 platform to reach ...

Abstract: The Internet of Things (IoT) has revolutionized the way we interact with the world around us. One of the many applications of IoT is in the field of home automation. In this project, we ...

前回の記事でもお伝えしたようにESP32にてWiFiを使う方法は大きく2つあり、1つはWiFiでルータに接続する方法で、これは前回の記事で紹介しましたね。今回はもう1つの方法であるESP32自体がアクセスポイントして接続していきます。 本記事では図1に示す ...

Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus RTU (RS-485) or Modbus TCP/IP (Ethernet/Wi-Fi). Designed for use in farms, ...

If you are an embedded engineer and working in the electronic industry, there may come a situation where you need to determine the position of a moving object or you need to determine the altitude and ...
