Dear sir, please contact me. We will discuss about your requirements. When I understand, I'll do it for you. As I understand, I'll make a php web app, and install in a Rasberry PI machine. From this Web app you can config "how to alert" (send to email, send to phone number...). It will get data from your board every 5 seconds (we can change this time interval). When it see some change, it will send alert to you (via email or phone number) please notice that, I don't understand all your requirements now so this price is not the final price, it maybe changed when I get all requirements.
