Paper SHT30 温湿度传感器
Begin()
功能说明:
初始化SHT30温湿度传感器
函数原型:
void Begin();UpdateData()
功能说明:
刷新检测数据
1.需要调用该API后才能获取新的检测数值
函数原型:
uint8_t UpdateData();GetTemperature()
功能说明:
读取SHT30检测到的温度
函数原型:
float GetTemperature(TemperatureScale Degree = Cel);GetRelHumidity()
功能说明:
读取SHT30检测到的湿度
函数原型:
float GetRelHumidity();案例程序:
