Knowing the surrounding physical information and react to what has been happened is important but not so difficult if we are there, otherwise it will be too hard. Fortunately, this problem can be solved by using Short Message Services
(SMS). By implementing a scriptexecution subroutine, the SMS becomes more
powerful and makes the sensor node become more flexible and interesting. It allows the user to read the surrounding physical information, to react and to change the setting after system installation by just writing script and sending it
as SMS.
