What PLC to choose energy-efficient, automated system?

I study faced such a problem:
It is necessary to design an automated system for measuring the temperature in the steam line, the resulting measurements should recover via GPRS modem to the station.
The question lies in the choice of the controller and modem that consume little energy, good between connectada and preferably are protected against temperature(60-80 degrees) and humidity(90%)
Perhaps you know a PLC with low-consumption, which you can hang a thermocouple.
Thank you read this)

if you have the box with electronics 60-80 degrees and even higher humidity, I have bad news for you
the need for small consumption is also not justified
and take Arduino and some sort of sim800 of examples in the Internet the bulk
it is possible to limit values operating temperature is normal 30-45
here the main question - some PLC modem) - yolanda.Lueilwi commented on April 4th 20 at 13:33
What nafig Arduino and steam pipe, you fell from the moon?! - benedict commented on April 4th 20 at 13:36
@benedict, ordinary Arduino in the normal case for the street
its inside the steam stick will not
as a PLC under the requirements of TS is banal do not let unnecessary - keith_Fah commented on April 4th 20 at 13:39
@keith_Fah, Arduino does not have all the protections and safety measures that has a PLC, it cannot be used as an industrial solution, and aguinsky library is a fierce terror in terms of control over the correctness and code execution time. - benedict commented on April 4th 20 at 13:42
@benedict, always something you have to sacrifice in this case, the lack of protections for autonomy.
as a stand-alone sensor is quite right to be - keith_Fah commented on April 4th 20 at 13:45
@keith_Fah, unfortunately will need is the industrial solution on Arduino will not work - yolanda.Lueilwi commented on April 4th 20 at 13:48
@benedict, even without the protection claimed me, the main thing is the normal inputs and negligible power consumption - yolanda.Lueilwi commented on April 4th 20 at 13:51
What is that study where they say "look for equipment on the Internet, and the teachers boom-boom"? - fatima commented on April 4th 20 at 13:54
@yolanda.Lueilwi, so I do not have Arduino normal inputs, there is a comb directly into the controller unsoldered. - benedict commented on April 4th 20 at 13:57
@benedict, that's understandable, therefore, need some kind of industrial solution - yolanda.Lueilwi commented on April 4th 20 at 14:00
@yolanda.Lueilwi, well then, all Google gsm temperature sensor
buy ready-made device and not worry - keith_Fah commented on April 4th 20 at 14:03
@keith_Fah, thanks for the advice, what can find - yolanda.Lueilwi commented on April 4th 20 at 14:06
