The following are the different versions of the Go Direct® Acceleration Sensor (GDX-ACC) that we have sold. Only the most recent version, released in April 2025, supports Remote Data Logging. Because of hardware differences, sensors that do not ...

Some Go Direct® Tris-Compatible Flat pH (GDX-FPH) were shipped with firmware that can cause the sensor to read a fixed pH of ~6.8 after a custom calibration. This issue can be observed in Graphical Analysis or on LabQuest App. To confirm that...

CBR 2 (CBR2) Specifications and User Guide Which Motion Detector model do I have? Troubleshooting Primary test: When you start data collection, do you hear a clicking from the CBR 2? If not, the sensor may be defecti...

Yes, it is possible to use a Vernier Ion-Selective Electrode (ISE) with an Arduino microcontroller. However, we do not recommend this combination unless you are familiar with the sensor's user manual and the complexity of how the sensor works, have ...

Since we started this company in the early 1980's, we have always tried to provide a way for teachers and students to "do their own thing", using our sensors. The following provides a list of coding environments that we support with libraries, docum...

Yes, we have created an Arduino library (named GDXLib) that allows Go Direct sensors to work with certain Arduino microcontrollers. The GDXLib library supports communication between the Arduino board and the Go Direct sensor via Bluetooth (USB is no...

Vernier has created Arduino libraries that support both Go Direct sensors and LabQuest sensors. These libraries have been officially added to the Arduino Library Manager. This means you can use the Library Manager tool in the Arduino IDE to install ...

The nominal dimensions of the Go Direct® Acceleration Sensor (GDX-ACC) are 68 mm x 27 mm x 17 mm. It has a mass of ~28 g. Go Direct Acceleration Troubleshooting and FAQs ...
