Top 5 Beautiful C++ std Algorithms Examples. Some time ago, I saw an inspiring talk from CppCon 2013: "C++ Seasoning" by Sean Parent.
One of the main points of this presentation was not to use raw loops. Instead, prefer to use existing algorithms or write functions that 'wraps' such loops. I was curious about this idea and searched for nice code examples. Here is my short list of usage of algorithms from the C++ std library that might help in writing better code. Of course. The Plan Insertion Sort In just two lines of code! For (auto i = start; i ! How It Works? Rotate(first, middle, last)- takes a range [first, last) and rotates it so that the middle element becomes the first in that range. upper_bound - Returns an iterator pointing to the first element in the range [first,last) which compares greater than val. How do those two elements combine into Insertion sort?
Std::upper_bound(start, i, *i) returns position of the first element greater than *i. Let's look at one example: Pretty nice! Quick Sort Found on Stack Overflow: Slide.

It is ideal for load monitoring without the need for an external power supply. ACS712 Low Current Sensor Breakout. Noncontact DC current-voltage sensor SD series 25A 50A 100A. 220.127.116.11 - Measuring Current (Including 4-20 mA) with a Resistive Shunt. The best way to handle 4-20 mA signals is with the LJTick-CurrentShunt, which is a two channel active current to voltage converter module that plugs into the UE9 screw-terminals.
The following figure shows a typical method to measure the current through a load, or to measure the 4-20 mA signal produced by a 2-wire (loop-powered) current loop sensor. The current shunt shown in the figure is simply a resistor. Figure 2.6-4. Current Measurement With Arbitrary Load or 2-Wire 4-20 mA Sensor When measuring a 4-20 mA signal, a typical value for the shunt would be 120 Ω. For applications besides 4-20 mA, the shunt is chosen based on the maximum current and how much voltage drop can be tolerated across the shunt.

Note: The i-Snail current transducer measures the current in a single AC wire (either the positive or the negative).
Formula The formula for converting SensorValue into AC Amps (RMS) is: Non-Invasive Current Sensor - 30A - SEN-11005. Description: This non-invasive current sensor (also known as a "split core current transformer") can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.
This particular current sensor will measure a load up to 30 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil's induced current to a very small measurable voltage. Documents: Measure-Current. How to measure current and power - using a hall effect transducer - clamp.
They can be totally isolated from another high voltage electrical system which eliminate risk to delicate monitoring equipment and also minimizes safety concerns. In other words this sensor only detects the magnetic field around the wire, there is no electrical contact between the sensor and the wire. This is a nice advantage over using a current monitoring shunt precision resistor. If your signal is too weak or you are not getting the resolution you want, you can simply loop the wire through the current clamp as many times as you want to double, triple, or quadruple the sensitivity or resolution of your sensor. For example, if your current signal is only .03 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 0.3 Amps.
Unlike the current shunt sense resistor which can have thermal temperature heat dissipation issues, the hall effect current sensor does not get hot. On Amazon.com. [Enlarge] like the one shown below.
