XDA Developers on MSNESP32 counterfeit devices technically exist, but that's not the full story
If you're worried about getting a counterfeit ESP32, you shouldn't be... though they do technically exist, but maybe not in ...
This project is an ESP32-based patient health monitoring system that measures room temperature, room humidity, body temperature, heart rate (BPM), and blood oxygen levels (SpO2). The system sends the ...

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, ...
DHT11采用单总线通信协议,即通过一根数据线同时实现数据的发送与接收,这种设计大大简化了硬件连接,但对时序的要求极为严格,任何微小的时序偏差都可能导致通信失败。 在数据传输过程中,DHT11通过高低电平的脉冲宽度来表示二进制的“0”和“1”。
最近遇到一些外包项目的老板,发现一个有趣的现象:大多数物联网项目需求里都明确要求使用ESP32。这让咱们这些STM32老玩家开始重新审视这两个平台的特点。经过一些项目实践和技术对比,我进行了一些简单的总结,希望对大家的技术选型有所帮助,同时免费 ...
在智能家居、气象监测、农业大棚等场景中,温湿度的精准测量是实现环境控制的基础,而DHT11作为一款低成本、易操作的温湿度传感器,凭借其稳定的性能成为众多电子爱好者和工程实践中的首选。这款看似小巧的传感器,内部集成了复杂的传感元件与信号 ...
