  Hello guys,i am working on a final year project and im stuck i intend to monitor the perfomance of cold rooms which are 200km away.I need to be able to know the i)temperatures at real time and ii) if other components like the compressor are working.
  
  i am asking for help in material,books,notes and also ideas.thank you in advance

  The only way is use GPRS Modem at Cold Room which monitors Temperature and all other parameters and updating it on server. So you can get real time data monitoring at 200Km away too. 😀

  Thank you Godfather for the info,now the question is? is the GPRS mordem capable of monitoring the conditions or i need to design a circuit (which monitors) then interface it to GPRS modem

  Exactly you have to design hardware and after that interface it with GPRS modem.

  good one though...
  for industrial and commercial purposes, if in case anyone wanting to implement this kind of solution kindly log on to #-Link-Snipped-# and #-Link-Snipped-#
  
  this might look like an ad...
  
  btw...
  for the solution to the problem i can give few tips though..
  1. always maintain potential free contacts for your digital inputs which will be encoded by you GPRS modem..
  2. make use of GSM SIM technique. use a SM with GPRS capability (airtel office pocket internet) and communicate the message in the form of a string to a particular port at your receiving side.
  3. for analog inputs like temperature first start with a scan time of 5 sec or 10sec and send the data to the GPRS module or else the 4-20mA or 0-10V data scanned will cause traffic and delayed messages. for EX: you might 250 deg c message first followed by 200 deg c ... u might think the temp is going down but then you will get 300 deg c message.. this will cause confusion...
  
  
  All the best ... these are practical problems faced till now

  This should help
  
  Use an IR or temperature sensor in the room
  
  the data op of this is fed to a GPRS modem also DTMF can be used to trigger this GPRS modem this will give more punch and increase the complexity at the same time

  Bob and Jeffrey thank for the upd8t let me look into it

  In modern engineering PLC-SCADA,system for remote monitoring is best.But it depends if you want to just do monitoring or controlling as well.

  Grsalvi thnk for the SCADA -PLC i will take it into consideration
