Abstract :
A digitalized system is proposed in this paper to acquire air pressure and air temperature data. The proposed method adopts a voltage-to-frequency converter to conduct the output voltage of the air pressure sensor, avoiding the traditional A/D convertion method. Beside, a 1-wire bus digital thermometer DS18B20 is chose in the system to measure the air temperature. Based on a micro unit AT89C52, this system can acquire data with a high accuracy and a low simplicity on the circuits.
