myDAQ myCapacitanceMeter

[Ashish_Naik_NIUK]

Introduction

Rhys Bowley shows how we can use LabVIEW, the NI myDAQ to build a capacitance meter both with a home made Capacitor and real world capacitors! All from a very sunny National Instruments UK

Materials Used

•        2x rolls of greaseproof paper
•        2x rolls of kitchen foil (preferably thinner in width than the greaseproof paper)
•        Sticky tape
•        Two lengths of insulated wire of about 30cm or more
•       1x myDAQ
•        NI Multisim
•        NI LabVIEW
•        2x 1Kohm Potentiometers
•        1x known capacitor i.e 10uF

Software

Multisim is used to simulate the circuit.

LabVIEW can then be used to analyze the values acquired from the capacitor.

Please see the attached file for code and instructions.
