Processing Circuit

A kind of multiple parameter data acquisition system was designed based on single-chip microcomputer which can realized the data acquisition of temperature and DC motor speed. The data acquisition system consists of sensor, signal processing circuit, single-chip microcomputer and LED digital tube. The speed signal is acquired by photoelectric sensor, put into the Single-chip microcomputer processed after processed by signal processing circuit, and displayed the value in the digital tubes. The temperature signal is acquired by digital sensor, and the Single-chip microcomputer can read the data directly. Through two independent keyboards, the test system realized the data acquisition and data switch displaying of the multiple parameters.

Humidity Monitoring

Exploring a kind of the humidity data acquisition system with higher performance-price ratio is vital to the environmental monitoring. At the present work, a novel of the humidity data acquisition system has been developed so as to collect and store the environmental humidity data. It consists of humidity sensor of DHT11£¬LED digital display and single chip microcomputer (SCM) of AT89S52. AT89S52 was used as the control chip which assembled with humidity sensor of DHT11 and digital display. Moreover, the behavior of humidity data acquisition was simulated with the software of Proteus; the results show that this designed system can collect the humidity data at bigger range. Therefore, the designed humidity acquisition system effectively achieves humidity monitoring, and has advantages of smaller volume, higher performance-price ratio, and portable.
