# Asp5033空速传感器

## 概述

{% hint style="info" %}
ASP5033传感器为穹刃®科技定制适合于无人机量程与采样精度的空速传感器，2023年3月后模块上有穹人®商标，请在购买里认清传感器上是否带有QIOTEK标志，使用非穹刃®生产的仿制假冒传感器，出现空速问题与故障请自行与假冒传感器销售方处理。建议从正规渠道购买ASP5033空速传感器。
{% endhint %}

{% hint style="danger" %} <mark style="color:red;">假冒传感器采样量程与采样精度均不达标，使用假冒传感器如出现问题，后果自负。</mark>

<mark style="color:red;">穹人</mark>®<mark style="color:red;">Logo已经为注册商标，我们坚持打击假冒行为，欢迎联系举报。</mark>
{% endhint %}

一直以来，价格高昂的数字空速传感器一直阻挡着固定翼玩家的普及使用，ASP5033空速传感器是为回馈玩家，由QIOTEK(穹人)®定制的一款空速传感器，我们通过三个月测试，并多次提交代码优化，最终通过ardupilot官方认证，完成驱动代码合并到空速传感器支持列表中去。ASP5033将于ardupilot4.1固件开始得到支持，请将飞控刷到ardupilot4.1以上。

{% hint style="info" %}
使用ardupilot4.3以上版本的1M Flash空间飞控，由于空间不足，默认固件驱动会移除本传感器，请按官方自定义固件定制教程构建固件，然后再使用自定义固件模式刷写固件使用。
