How do I read the movement scheme?
If you want to create your own home security system, you need to know how to read the movement scheme. This shows all required components for creating the perimeter of the movement detector and shows how these components are connected and the power supply. Such schemes are read as much as any other scheme because they use the same symbols. If you have not read the movement scheme yet, you can do so to identify components according to their symbols and how complex components are identified, such as integrated circuits (ICS). You must also learn to identify the power supply and be able to combine the scheme for areas where some components are connected indirectly.
Almost every scheme uses the same symbols to identify components. You can learn to identify them using electronics for beginners or online chart. Looking at the symbols, you should notice that you stretch the lines from one or more ends of the symbol. These lines represent a lines or pins of the componeny. Occasionally there are small changes in the symbols used in the scheme. For example, a resistor can be represented either by a winding or a rectangle.
It is common that the movement scheme includes complex components such as ICS. IC, which are sometimes referred to as chips, are usually represented by rectangles and triangles. If you see a triangle, this means that the IC is a specific type called an operating amplifier (OP-Amp). Each IC is also identified as a model name, which usually consists of numbers and letters. The model name allows you to find IC and buy the right component.
sensors, such as passive infrared (PIR) sensors and cameras, rectangles can also be identified in the movement detector scheme. In some cases, the scheme designer could use a particular symbol that he suggested. Sensors in the scheme can usually be identified according to their parts or model names. PokUD is the part number, search for it in the district parts list.
are usually three or more pins of IC or sensor connected to other components. In the motion detector scheme, these pins are usually identified according to their numbers and sometimes their functions. If the diagram identifies the pins according to their functions, you will need to find a data sheet of a component that should be available from the component manufacturer. PIN numbers are sometimes listed from the order in the scheme, so it is important to pay attention to the location of numbers.
Like all schemes, the movement scheme uses full lines to indicate the connection between the components. It is common for the line in the scheme overlapping, especially when one shows the design of a complex circuit. For example, you may notice that a series of the horizontal lines overlaps a series of vertical lines. The intersections of these lines do not always represent a connection. Usually the circle is used to identify the connection between overlapping lines.
To make the electronic circuit of the fungoVal, must be connected to the power supply consisting of the ground, also called country and positive tension. The country is usually represented by three horizontal lines and positive voltage is usually represented by a plus sign. Schematics also refers to the type of energy, such as direct current (DC) or AC current (AC) and the number of volts needed for proper functionality. Power is often displayed at the top or left side of the scheme.
Schematics of a large movement detector can be divided into several pieces on a page or on several pages. You can find out how the pieces of the scheme meet search by searching for symbols, numbers or words on lines representing connect. For example, the first part of the scheme may contain IC with numbered pins and the second part may contain other components with numbered lines into these components. In this case, the numbers are IC pins.
