One of the most popular gateways is NowSMS since it can work very well with mobile phone that soon
will operate as a GSM modem where Sony Ericsson k800i had been preferred. Configuration process is
important to make sure that SMS gateway can work well with the mobile phone. 
Alert system will be activated only if the normal parameter range is exceeded. Normally, the temperature
and humidity of tissue culture did not change rapidly. In many cases, the next reading will be more or less
than previous reading. It is quite troublesome  since monitoring process is done manually by using
thermometer and hydrometer. The problem typically occurred during weekend or holidays since there is no
one available to do the monitoring process. Worst case scenario is electrical supply failure when its blackout,
the tissue culture will definitely contaminate be due to the inconsistency of temperature and humidity. Fig. 3
shows the data of temperature and humidity in tissue culture growth room at MPOB.

The suitable parameter for temperature is between 25°C to 30°C while for humidity is between 45% until
90%. If the parameter range is exceeded, alert system will notify the user by sending SMS and email
notification. Fig. 4 shows the temperature and humidity graphs of tissue culture in growth room.

SMS and email notifications display shows in Fig. 5. The SMS information are including the subject,
parameters range, date and time as well as the current value of parameters. The email notification shows the
sender’s address, date and time, recipient’s address, subject, the parameters range as well as the current value
of temperature and humidity that had been triggered by alert system.
