Abstract :
An real-time temperature and humidity measurement system is designed with SHT21 temperature and humidity sensors. Communication is controlled by XC2S50-5TQ144 Field programmable gate array and measurement data can be shown in real time by the PC software. The results show that the system can not only accurately measure the real-time temperature and humidity, but also rapidly respond to the mutations in surroundings temperature. The accuracy of measurement system is up to 0.001 of the requirement and realizes the maximum balance between miniaturization and high performance of system.
