We could use an specific integrated circuit used for VU meters, but we decided to use a readily available integrated circuit: The LM324 op. Battery Monitor Circuit Diagram Using Lm Pictures, Battery Monitor Circuit Diagram Using Lm Images. CAPTCHAThis question is for testing whether you are a human visitor and to prevent automated spam submissions. The IC is configured to give a 'dot' display, in which only one of the ten LEDs is illuminated at any given time. Here enclosed its picture & our catalog for your reference, if you are interested in anything or for any question, please don't hesitate contact me! A very simple bargraph voltmeter electronic project can be designed using the LM3914 digital voltmeter IC. Car voltage monitor (XL-Car-V)Monitor the car battery level via cigarette lighter socket.Just plug it into cigarette lighter jack. The regulated +5 V supply can be derived from the car’s cigarette lighter receptacle (12 V output) using LM7805 regulator IC.Ĭar Battery Checker[WE ARE LOOKING for OVERSEA Distributor, Also you can sell them using your LOGO, we will engrave your company inf. Hello Readers, We frequently add new circuit diagrams, so do not forget to come back often.Īs I said this project is simply about making a precise digital voltmeter that plugs in to the car’s cigarette lighter receptacle and displays the instantaneous voltage across the battery terminals. The non-inverting pin of operational amplifiers are connected to a voltage divider network, composed of several resistors in series. The output signal of an audio amplifier (which is connected to the input to the speaker), is applied to all the inverting inputs of the operational amplifiers, through resistor R1. R1 and R9 form a voltage divider to reduce the amplitude of the input signal. Condition: New, Brand: Unbranded, Measuring Range: 9-31 (V), The input Voltage: 12-24 (V), Voltage Measurement Error: 0.1-0.This 8 LED VU meter circuit can be used to display the variation of an audio signal in a group of 8 LEDs, behaving like a VU meter.

Specification: Measuring Range: 9-31 (V) The input Voltage 12-24 (V) Voltage Measurement Error: 0.1-0.3 (V) Dimension: 70*40*30mm (Approx) Package Contents: 1 * Car Voltmeter Notes: 1,The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. High brightness red LED three digital display, easy to read. Designed to measure the car battery voltage value and monitor the battery voltage, make the working voltage of battery in normal use, extend the service life of and protect the battery and motor. Easy to use, just need to insert into the car cigarette lighter socket.
