  • Digital Voltmeter Meter Module

    posted by jk87

    Very handy thing for DIY projects. Small mounting dimensions. Nice (blue) backlight. Quality workmanship. A very useful addition when you need to measure the voltage of one cell. I use to check discharge of an article in its grip e-cigarettes.
    Nothing I could find. Maybe if he had a greater range, but there are other modules.
    Ideal for ecig grips, or wherever you need to measure voltage of a Li-Ion cells. Plans to use a portable power source.
  • Small and practical, but not very accurate.

    A small and practical module. It can easily be mounted.
    I thought that it would work the same as sku187376 only with extra power supply, but it was way more inaccurate. If you only need measurement from 2,5V to 30V i recommend sku187376 instead.
    The measurement range of 0-100V make it inaccurate. It varies about half a volt.
  • Extremely useful add-on for any recent economy car

    Very good add-on which allows control of your electrical system and therefore reduces the possibility of getting stuck on the road. Will efficiently indicate the battery condition and the alternator function. Also will detect unexpected discharges.
    Very useful add-on. I recommend the purchase. The Price and quality is fine.
    The modern economy cars lack totally of electrical system supervision, at least for the owner. This Volt-Ammeter add-on solve this problem.
  • Great little device.

    This is a very usefull, precise and cheap device and it draws almost no current. Possibility to calibrate with potentiometer at the back of the panel.
    I've hooked this up on a 11.1v Lithium battery, showed 11.0v after 24hours it showed 10.8, so this thing really draws little current.
    Very handy little voltmeter, can be used in projects for monitoring, or just when you quickly need to measure something and don't want to use your multimeter!
  • nice display

    I like this thing a lot, i had another one in red without the frame and it didn't look as good as this one, the blue color is nice and even, no dark sports, and seems fairly correct to me. The black surrounding around the display is made of the same material as most dashboards so could be integrated very wel in a dashboard without noticing. The display has a matte cover over it to enhance visibility in the sun or bright daylight.
    This is the way to go is you want a nicely finished display with a case to match so you can build it in in something
