如题,重力传感器hx711代码
- #include "HX711.h"
- float Weight = 0;
- void setup()
- {
- Init_Hx711(); //初始化HX711模块连接的IO设置
- Serial.begin(9600);
- Serial.print("Welcome to use!\n");
- delay(3000);
- Get_Maopi(); //获取毛皮
- }
- void loop()
- {
- Weight = Get_Weight(); //计算放在传感器上的重物重量
- Serial.print(float(Weight/1000),3); //串口显示重量
- Serial.print(" kg\n"); //显示单位
- Serial.print("\n"); //显示单位
- delay(1000); //延时1s
- }
复制代码- #include "hx711.h"
