Hi all. Im new here and i need advice and assistance about my project.

I would like to create device that can monitor temperature.(as in industry they use something to heat or chill that needs certain degree of temperature). A friend told me that the existing device in his company uses PLC (not sure for what, control maybe?), Thermocouple (temperature sensor), LCD touch screen (as HMI). i think thats the main parts.

I would like to substitute PLC with Micro controller such as arduino. is it possible to substitute LCD touch screen with Touch screen shield for arduino? the reason for those substitutes is price. or is there any good recommendation for the HMI? i also need that this device could store log data. Further i want to add buzzer to notify the operator if temperature goes too low or too high.

how you guys think, is it possible to add parts and substitutes parts that i mentioned ?

thanks in advance!

as screen and µSD socket (to log data), you could use thhis combination:

Screen
µSD shield

It has a touch screen interface, as well as an SD card to store data.

great. that would be nice since i think its cheaper than single LCD touchscreen that not integrated yet with arduino. btw what kind of arduino that i should choose? what things that need to be considered to choose the right type? (uno,mega,pro,etc)

maybe the problem is if the shield is available in the local distributor

any other suggestion folks?

or maybe one of you had ever done similar project?

this is a similar project - http://www.ladyada.net/make/logshield/lighttemp.html - complete with instructions.

Hi,

i do temperature monitoring, for different purposes (room environment) . For that purposes I create my own shields and few other PCB-s .

For data loging and storing configuration I use Data Loger v 1.0 shield (look at http://pcb.daince.net/doku.php?id=data_logger ), also same shield have pin header for connecting simple LCD (20x4) and 5 switch keyboard (analog line).

For connection of temperature probe I use A/D Expansion Shield http://pcb.daince.net/doku.php?id=ad_expansion, and use Maxim IC DS18B20 1-Wire sensors.

Finally for alarms I use I2C Digital IO Board http://pcb.daince.net/doku.php?id=de_twi_status_led_lcd two RGB LEDs with red-green-blue sequence (hot-normal-cold) , and 2 orange LEDs signal changes (or you may use buzzer).

Mostly all of code may fit in 32KB, but because of price and convince i use Arduino MEGA 256.

Hope that help you.

Best regards,
Dubravko Penezic

thank you folks, this really helps.

Hi All,

for HMI visualization you can use our Software VisBee.
Actually  we are working on the driver to communicate between ARDUINO and our visualization Software VisBee.
MODBUS (and others) is already working.

It’s a fully loaded professional Visualization system for HMI and SCADA.

You can download the Software without any restrictions at www.visbee.de (english version)

The is a extra version for ARDUINO - Fans ;-)  (VisBee-light)

The driver will be available during march/april 2013.

If you have further questions let me know.....

BR,
Chris
