Learn how to publish temperature and humidity readings from a DHT11 or DHT22 sensor via MQTT with the ESP8266 NodeMCU to any platform that supports MQTT or any MQTT client. As an example, we’ll publish sensor readings to Node-RED Dashboard and the ESP8266 will be programmed using Arduino...
1. 解码空调红外键值1.1 安装 IRremoteESP8266 库1.2 把ESP8266红外接收的实例,上传到NodeMCU中.1.3 读取遥控器红外键值 把红外接收模块的信号线连接到GPIO14(Node MCU 对应D5引脚) 红外接收模块接线图,型号:VS/HX1838B 打开Arduino 调试串口监视器,选择波特率为115200 空调遥控器对准红外接收管,按下需要的按键,串...
As you see, the MPU6050 has 8 terminals but in order to connect with ESP32 and ESP8266 NodeMCU, we will only require the first four pins highlighted in yellow. These are VCC, GND, SCL, and SDA. The table shows the connections between the two modules. The VCC pin is connected with th...

ESP8266 NodeMCU Web Server with BMP388 We have a similar tutorial for the ESP32 board: ESP32 with BMP388 Barometric/Altimeter Sensor (Arduino) Introducing BMP388 Barometric Sensor The BMP388 is a precise, low-power, low-noise absolute barometric pressure sensor that measures absolute pressure and...
ESP8266我用的是安信可的开发板(NodeMCU-12F CH340版本),具体的硬件参数和电路原理图这里就不发出来了,不同的板子引脚可能会有差别。TFT LCD彩屏不管用的是什么驱动IC,硬件上基本都是一样的,通讯方式常用的是SPI、并口、IIC等,并口有4线、8线和16线,并口速度是最快的,但需要的引脚资源也多,SPI占用的硬件资源...
To use timer wake up with ESP8266, you need to connect the RST pin to GPIO 16 which is labeled as D0, in aNodeMCU board. Simply follow the next schematic diagram: Connect the RST pin to GPIO 16 only after uploading the code.
