Data acquisition is a vital part for industrial and agricultural control system. This paper aims to de-sign and develop an environment testing system for cabin with AT89C51 and ADC0809 analog-digital conver-sion as its core. The proposed system is composed of temperature and humidity acquisition, data conversion module, signal display and LED dynamic display modules. The system will favor operators in operating room to master and control the cabin environment with saved labor, enhanced security, and improved automation level.
