The Vernier Arduino® Interface Shield (BT-ARD), has four sensor ports; two analog and two digital. The shield connects the sensor lines to the following Arduino pins: Analog 1 Sensor pin 1 (+/-10 V output line) - Arduino pin A1 Sensor pin 2...

Vernier does sell a Dual-Range Force Sensor (DFS-BTA), and a Go Direct® Force and Acceleration Sensor (GDX-FOR), that can be used for this application. We have not tested these sensors in-house, but several college professors have told us that th...

Vernier currently sells four different types of Heart Rate sensors, the Go Wireless Heart Rate, the Go Wireless Exercise Heart Rate, the Hand Grip Heart Rate Monitor and the Exercise Heart Rate Monitor. All products use a Polar Transmitter Module, th...

When we update our lab books, we review all the experiments. Occasionally, we revise experiments to fix errors or remove equipment that can present an unnecessary hazard to students. In 2017, when we released the 4th editions of Middle School Sci...

There are a number of items to check, in this order, before we conclude the balance needs to be returned for repair/replacement. After completing each item, measure a solid object with a known mass. 1. Make sure the balance pan is not locked. OHAU...

This article refers to the Go Direct® 3-Axis Magnetic Field Sensor (GDX-3MG) For information about the Magnetic Field Sensor (MG-BTA), see Magnetic Field Sensor Troubleshooting and FAQs The Go Direct 3-Axis Magnetic Field Sensor has two range...

The Vernier UVA and UVB Sensors respond to specific regions of the electromagnetic spectrum. The wavelength region from 320 to 400 nm is commonly called UVA radiation, and 280 to 320 nm is called UVB radiation. Wavelengths shorter than 280 nm fall in...

The Charge Sensor (CRG-BTA) contains several capacitors which ideally should maintain a constant state when the test leads of the sensor are in electrostatic equilibrium. However, environmental conditions such as local humidity, nearby static charges...

KidWind simpleGEN (KW-SGEN) and GENPack (KW-GP) are both kits to allow students to make a basic AC generator. Short version: The SimpleGEN is simpler and we recommend it for for Middle School, High School, and College. We recommend the more adva...
