With the advances in open-source technology, many laboratory devices can be built with a modest budget, particularly assistive laboratory devices. The current market cost of most assistive laboratory devices is a major barrier for students with accessibility needs. Specifically, for students with visual impairment, their limited choice of laboratory assistive devices has motivated us to construct a low-cost, multipurpose sensor hub capable of connecting to a pH electrode or a thermocouple, two sensors commonly used in many chemistry teaching laboratories. In this technology report, we present the construction of a text-to-speech (TTS) multipurpose universal chemistry sensor hub (MUCSH) built using an Arduino platform and other associated open-source electronic parts. The cost of this device is between $200 and $300, a fraction of the cost of commercially available products, which cost thousands of dollars.

在地下实验室中将创客运动与可达性需求相结合：面向残障学生的具有成本效益的文本到语音多功能通用化学传感器中枢（MUCSH）

随着开源技术的进步，可以用适度的预算建造许多实验室设备，尤其是辅助实验室设备。当前大多数辅助实验室设备的市场成本是有无障碍需求的学生的主要障碍。具体来说，对于视力障碍的学生，他们对实验室辅助设备的有限选择促使我们构建了一种低成本的多功能传感器集线器，该集线器可以连接到pH电极或热电偶，这是许多化学教学实验室中常用的两个传感器。在此技术报告中，我们介绍了使用Arduino平台和其他相关的开源电子零件构建的文本语音转换（TTS）多功能通用化学传感器集线器（MUCSH）。该设备的价格在$ 200到$ 300之间，
