Abstract: This work presents a cost-effective approach to implementing programmable logic controllers (PLCs) for educational use, using commercial microcontrollers (Arduino UNO, ESP8266 NodeMCU) and a ...

Serial Studio turns data from your hardware into a live dashboard. Connect an Arduino, ESP32, STM32, Raspberry Pi, Teensy, or anything else that speaks serial, Bluetooth, a network protocol, or an ...

Electrical energy is no longer treated as an unlimited utility. Every watt consumed has a cost impact, an efficiency implication, and in many cases a safety consequence. A smart grid in IoT is not a ...

[导读]在本教程中，我选择了来自Waveshare的ESP32-P4高性能开发板，因为该开发板是按照众所周知的树莓派的外形设计的。这意味着树莓派的现有hat也可以与ESP32-P4一起使用。MODBUS RTU连接需要RS485接口，本例中为Zihatec的树莓派提供RS422/RS485 HAT。 Modbus RTU与Waveshare ESP32 ...

Waveshare RP2350-Relay-6CH is a Raspberry Pi RP2350-based industrial 6-channel relay module with an isolated RS485 interface, 7 to 36V DC input via a terminal block, and support for Raspberry Pi Pico ...

ESPuno Pi Zero is a Raspberry Pi Zero-sized board based on an ESP32-C6-MINI-1 WiFI 6, BLE, and 802.15.4 wireless module and an SMPS that allows up to 60V DC input via a 2-pin terminal block. The board ...

In the domain of IoT and automation, the book Coding Modbus TCP/IP for Arduino offers a comprehensive exploration into the integration of Modbus TCP/IP communication with Arduino. This book provides a ...

The world of wireless communication has been revolutionized by the advent of Long Range (RF) technology, offering a blend of long-range capabilities and low power consumption. The EByte RF E70 module ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...
