Science Sensors and Interfaces

The Go Direct® Science Sensors and Interfaces, developed and manufactured by Vernier Science Education, are a family of modern, all-in-one sensors built for real-time data collection in classrooms and labs. These devices feature multiple types of connectivity, including the ability to communicate directly with calculators such as the TI-84 Plus CE, the TI-Nspire CX II, and the Ti-Nspire CX II CAS. Students can collect, graph, and analyze scientific data through software like Vernier’s free Graphical Analysis apps or TI calculator integrations. Designed for hands-on experimentation in subjects like chemistry, physics, and environmental science, the sensors include built-in rechargeable batteries, many different sensor types, and are simple to use, which helps support STEM learning at all levels. Go Direct sensors streamline experiments, enhance engagement, and help students make real-world connections through science.

Let customers speak for us

from 401 reviews

Purchased a class set of calculators at a fair price. We didn't need calculators for quarter 1 so I didn't notice for nearly 2 months but the order was a little off and they remedied it no questions asked. Fantastic company with real customer service.

Happy with New Charger

Very pleased with my purchase and this company.
My order arrived in good time, and all the items were packed well.
I needed a new charging wire and plug for my graphing calculator. I didn't want to purchase from 3rd party merchants, just in case they were inferior products. So I found the originals here. So glad I did. Thank you! Would purchase from here again with mo hesitation.
