is arduino reliable for industrial environment for industrial application?

Agree with Michael

Arduino is an echo system to allow rapid development and education without having to get out the soldering Iron for instance, the boards in general lack the protection circuits often required in industrial applications to protect the controller as well as many other potential safety and environmental considerations. I have some experience building systems for the gas industry and in this kind of environment it would not be allowed for instance.

This does not mean that the micro-controller (ATMEGA328 on the UNO) is not suitable for use in industry, you just have to add all the other electronics required to meet the standards. The same goes for TI MCP430 series or other brands. In some areas like Automotive there are very strict requirements which is why you will find a significant percentage of cars use Motorola Micro controllers (Yes they do make them and yes you may never had heard of it). The chips are approved for use in this industry, the approval is expensive but there you go.

As Michael said though, it depends on the specific industry and use and must be evaluated on a case by case basis. If it is a one off then you may simply have to make suitable modifications to the board and container to meet the legislations required for that use. If it is going in a field to measure temp and humidity, there is pretty much not much required except protecting from the elements (Unless the field is in a certain town in England sitting on top of 20M cubic feet of natural gas at 1000PSI  yes it exists and I put a controller there )

anyway I think you get the idea.

Have fun, be safe

hello peter

iam new to arduino i just done temperature monitor project with arduino,now i want to develop a project using current sensor CT coil that senses the running current of a ac application.

can you suggest me in this.

thanks in advance

Well the one nice thing about using a current sense coil or a hall effect current sensor is your circuitry is isolated from the mains but you still have to wire your sensor into it by disconnecting the mains wire and feeding it through the coil or the hall sensor current side circuit, this is the most dangerous part

once this is done, the low side monitoring is relatively straight forward but depending on your skill level may change your approach (AND YOU STILL HAVE TO BE AWARE MAINS IS IN CLOSE PROXIMITY AND WILL KILL YOU GIVEN A CHANCE )

First you need to ensure the output of the sensor is within range of the Arduino being used, for an UNO this would be 0 - 5V. now your current sense coil probably gives out an AC signal still so it will need to be rectified (Simple Diode  should work here) and then optionally smoothed with a capacitor to then be read by an ADC in the UNO. the other option here is to take the rectified signal but not smoothed into the ADC and sample at a quicker rate, you could then also measure the AC frequency and possibly perform true RMS calculations on the data to get more accurate readings.

Without knowing the actual parts your going to use for the current sensing it is hard to provide better info but this should give you enough to think about your approach

Provide a little more details and we can help better

for practice and experimentation prior to hooking up to the mains I would suggest using a transformer with say a 3V AC output and get skilled at measuring this using the Arduino first, this way your not worrying about the actual measurement once your adding the current sensing into the mix

At the measurement end there is no difference, the Arduino can not measure current. Actually most multimeters don't measure current, they nearly all convert it to a voltage first and measure that. Hence the use of a current shunt resistor

hope this gets you started
