汽车空调温度湿度传感器设计

Design of temperature and humidity sensor for automobile climate controlling

车用温度湿度传感器用于对汽车车厢内温度和相对湿度的自动监测,其性能直接影响空调系统的工作.设计的温度湿度传感器采用了一体化结构和强制空气流通的措施,能够在-30～85℃的环境中连续工作,并在湿度为20%～90%RH的范围内达到±5%的准确度,同时,具有较好的线性度.

The temperature and humidity sensor is used to measure the temperature and humidity of automobile compartment automatically： Its performance can affect the work of the system directly. The temperature and humidity sensor adopts the design of integration structure and the measure of forced flow of air. It can continuously work at the temperature of - 30-85℃, the precision is up to ±5 % at the range of 20 %-90 % RH, and the test results show that they have a good linearity.
