System designing of multi-data gathering and wireless transmission
【Abstract】: This is an monitor system with multi- data gathering and wireless transmission. The data of the real time temperature which are gathered by the temperature sensor(DS18B20) are transmitted to the master machine(AT89S52) from the slave machine(AT89S52) through the wireless transmission module. Then the data will be displayed by the master machine and transmitted to the PC for further processing. Other kinds of sensors also can be used for the data gathering.
