一、硬件准备Arduino ESP8266/ESP32开发板多路DS18B20温度传感器杜邦线若干面包板电源适配器二、硬件连接将DS18B20温度传感器焊接到杜邦线上，以便于连接。使用杜邦线将DS18B20温度传感器的数据线连接到Arduino的数字引脚上，建议使用4-5个数字引脚。将电源适配器连接到Arduino的VIN和GND引脚
In this tutorial, we will learn to interface temperature sensor DS18B20 with ESP32 using ESP-IDF library. This guide will include a brief description of DS18B20 sensor, pinout, connection with ESP32 board and then setting up a project in VS Code with ESP-IDF extension to acquire the sensor ...
下面是一个DS18B20设备的驱动函数: importtime,ds18x20 ds=ds18x20.DS18X20(ow)roms=ds.scan()ds.convert_temp()time.sleep_ms(750)forrominroms:print(ds.read_temp(rom)) 注意 确保数据引脚连接了 4.7k 的上拉电阻。另外请注意每次采集温度都需要用到 convert_temp() 模块。
ds18b20传感器引脚定义: 注意:信号线和电源线之间需接上拉电阻,电阻值可选1K-100K欧姆,本节点选择了5.1K电阻。 将信号线接到esp32的GPIO4上: 在这里插入图片描述 温度显示节点 在这里插入图片描述 接线方法: 在这里插入图片描述 在这里插入图片描述 温度检测节点提供的服务 我在南京江北新区,所以温度检测节点提供南...
