5-30V 0.36 inch DC Voltmeter Panel Digital LED

This is a 0.36" LED display mini 30V DC digital volt meter panel in Red Color. This voltmeter can read voltages ranging from 5 volts to 30 volts. It is simple to use and a great replacement for old, difficult-to-read analog panel meters in projects.

Only two wires are needed to interface this device with the target circuit and the DC voltage used for powering the meter is from the target circuit. This assures simple, trouble-free installation.

Package Includes:

1 X DC Voltmeter Panel Digital LED (5-30V)

Applications:

• Project power supply monitoring up to 30V
• The monitor battery voltage of a car, motorcycle, truck or bus which have 12v /24v batteries
• Monitor UPS, Home Inverter Batteries of 12V/24V or Solar Panel voltage.

DC Digital Voltmeter Panel Product Description (Wiring Details):

DC Digital Voltmeter Panel Application Circuit:

Below is a circuit for monitoring the supply using the digital voltmeter for an Arduino UNO project. The supply voltage and measure voltage for the module are connected in this example; which can be handy for detecting brownouts and the like. The measurement voltage is connected to the RED wire. The ground is connected to the BLACK wire.

Note - The DC supply voltage should not reduce less than 3 volts and should not be greater than 30V (these are the min/max values of the display).
