This VI takes input from the Vernier Biology Gas Pressure Sensor (BGP-DIN) and calculates the pressure above ambient in Pascals.

Use the LEGO-Vernier adapter with this sensor on a blue input port.

This VI takes input from the Vernier student Force Sensor and calculates force in Newtons. NOTE: YOU NEED TO CALIBRATE AND ENTER COEFFICIENTS INTO THE DIAGRAM.
