Voltage indicator - On many devices, we meet the required level of voltage or current. Regardless of whether we are working on its own design laboratory power supply, or on a simple charger to charge a car battery, the correct device for the measurement of key parameters provides a reliable measure with sufficient application accuracy. The store Botland, you will find a simple, analog gauges, and finished devicesthat are useful in everyday work electrical and electronics.
The module is based on the KA2284 system. It is used to measure the input signal with the 5 LEDs, which are gradually included depending on the value of the measured voltage. It can measure voltage AC or DC (selected using jumpers). Sensitivity is adjustable with a potentiometer. Works with voltages from 3.5 V to 12 V.
A module designed for reading the Li-Pol 3.7 V battery charge level in real-time. It is also equipped with alarm function when the battery level is low, or when battery power drops below a certain threshold, helps to estimate the battery life. In projects that run on solar power it helps to register the rate of change of battery power even within a month.
qualMeter is a simple DIY device that enables you to diagnose the quality of your USB charging cable and the charger itself. It allows you to check wires type: female microUSB A, female mini-usb, female USB A, female to 8-pin, female 30-pin.

Voltmeter analog, that is, analog voltage meter, the longest present on the market a kind of pointer to a value of voltage. Previously, each voltage indicator, from the simple meter of the diffuser in the receiver and magnetofonach blade, after the high-class laboratory equipment was equipped in the so-called "system" measurement. The principle of operation of such element is quite simple: the current flow through the light, thin coil, connected with the Board, causes it to rotate relative to the permanent magnet. The rotation angle depends on the voltage, and this, in turn, a certain coil resistance is proportional to the value of the voltage at its terminals. So we see that the same measuring device, depending on the connected (or no) additional resistors, can be used as a ammeter and voltmeter.
Today, despite the universal availability of digital devices and their low prices, still willing to apply the use of voltmeters and amperomierze wskazówkowe. As an example may serve the device, stylized old – lampowe audio amplifiers are the best proof of the enduring popularity of traditional indicators. Also a simple power supplies, including laboratory, are often not typical of the LED display, but the analog voltage indicator. Cheap electrical devices of everyday use, such as car charger, also use repeatedly with sensors wskazówkowych.
Yes! Of course, if we mean the detection of hidden in wall wires or metal elements. For this purpose, voltage detectors, in a position a small distance, to detect an electrical wire in which a current flows or breaches of the magnetic field caused by metallic objects (e.g. rebar). For installers and DIY excellent use will also "długopisowy" voltage indicator, which makes it easy to determine the phase wire in the electricity network.
