ALAT PEMANTAU SUHU JARAK JAUH BERBASIS SMS (AN SMS-BASED REMOTEe TEMPERATURE MONITORING DEVICE)
Abstract: A remote temperature
monitoring device based on the GSM (Global System for Mobile Communicatiobn)
Short-Messaging Services (SMS) has been designed and constructed. The device is
controlled by an AVR AT90S2313 microcontroller. Connected to the
microcontroller are the temperature sensor and a cellular phone. A user, using
another cellular phone, can query the status of the temperature by sending an
SMS to the cellular phone attached to the microcontroller. Upon receiving the
SMS, the device will read the SMS, interpret the SMS content as a command to
access the temperature readings, compose a reply SMS and command the attached
cellular phone to send the SMS to the querying cellular phone. The device has
been implemented and tested on a series of Siemens cellular phones and has
shown a good performance with the only predominant limitation being the
availability and signal strength of the GSM infrastructure.
