| Abstract: | Based on the ARM and DS18B20 temperature monitoring system use ARM as the data acquisition unit and digital temperature sensor DS18B20 as the temperature detection element. The overall system design, hardware design and software block diagram are given. The digital filtering of measured data is the average median filtering method.Meanwhile, the acquisition system connects the host computer via the serial port in order to achieve the network monitoring function. |
