SHT30 软件包给了一个说明文档，路径为 packages/sht3x-v1.0.0/docs/api.md，可以使用命令对其进行测试，如下
## sht3x MSH命令

`void sht3x(int argc, char *argv[])`

- sht3x probe <i2c_dev_name> <pu/pd>  --挂载SHT3x设备，需要指定i2c设备名称和上下拉方式，默认下拉
- sht3x read --阅读SHT3x温湿度
- sht3x status --读取查看状态寄存器值
- sht3x reset --软件复位SHT3x
- sht3x heater <on/off> --开/关heater

MSH用例:
```c
msh >sht3x
Usage:
        sht3x probe <i2c dev name> <pu/pd> -- probe sensor by i2c dev name and pull config
        sht3x read -- read sensor sht3x data
        sht3x status -- status register of sht3x
        sht3x reset -- send soft reset command to sht3x
        sht3x heater <on/off> -- turn on/off heater of sht3x

msh>sht3x probe i2c1
sht3x probed, addr:0x44

msh >sht3x heater on
sht3x heater cmd sent

msh >sht3x status
sht3x status:
        checksum:       0       - 0 means checksum correct
        command:        0       - 0 means last cmd executed OK
        reset deteced:  0
        alert pending:  0
        T track alert:  0
        RH track alert: 0
        heater enabled: 1

msh >sht3x heater off
sht3x heater cmd sent

msh >sht3x read
sht3x humidity   : 39.9
sht3x temperature: 24.5

```
