Abstract
A monitoring design for isolated zone ecosystem based on GSM GPRS + GPS SIM508 has been successfully carried out. The monitoring system consists of several
subsystems. They are multi sensor system, microcontroller, data transmission, and
autonomous energy system which are integrated each other, and be able to provide
information in the form of physical quantities. This system was designed to work automatically using an ATmega8535 microcontroller in order to control the whole system. In order to detect physical quantities i.e temperature and humidity, a series of
multi sensors used a SHT75 sensor and a LM35DZ sensor that had been calibrated and
characterized. Results of the sensor system readings were converted by a microcontroller of ATmega8535 before it was sent to the SIM508 module. SIM508 module was used as data transmitter. Testing of the monitoring system was done using a Hyperterminal. Results provided the information of temperature, humidity, time and location. There information were sent by the monitoring system via short message service (SMS) to Mobile Phone. The monitoring system works well and has a high
degree of accuracy
