AURDINO AC VOLTMETER 0 to 230/300 VAC MEASUREMENT USING LEAF VOLTSNS300 V1

Introduction: AURDINO AC VOLTMETER 0 to 230/300 VAC MEASUREMENT USING LEAF VOLTSNS300 V1

Here is a useful circuit for Arduino lovers and

experimenters.

It is a simple digital voltmeter, which can measure input ac voltages in 0 to 300V range. The Arduino board can be powered from a standard 9V battery pack, as usual.

As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range can be increased by using LEAF VOLTSNS300 V1.

Important Note :: This sensor Needed calibration initially with actual voltmeter.

During first time use. use one voltmeter check voltage and using POT set accurate Value in Arduino serial since value in AC and DC for sensor will be different .
