德州仪器HDC1080温度湿度传感器golang库
ti hdc1080 temperature and humidity sensor golang library

---

这个库使用 golang 编写，用于操作hdc1080温湿度传感器。

This library written in Go programming language intended to operation hdc1080 sensor chip.

---

Usage

func main(){
hdc1080, err := NewHdc1080(0x40, 0)
if err != nil {
// ....
}
defer hdc1080.Close()
temp, err := hdc1080.GetTemperature()
hum, err := hdc1080.GetHumidity()
}

详细使用方法参考 hdc1080_test.go
