Abstract

Considering the requirement of temperature and humidity to a good condition for the old people in the family nursing, a temperature and humidity data acquisition system has been designed in detail based on the ARM920T processor and the controller S3C2440 in this paper. DHT91 sensor is utilized to collect those data which is connected with the controller through a 2-wire serial interface. The parameter data can be displayed on the local LCD and also can be transmitted to the computer through RS232 or RS485 serial interface for further analysis. The carried out experiments show that the system is stable, reliable and practical.
