The humidity sensor performance in several ways to make a preliminary judgment

In actual humidity sensor calibration difficult circumstances, through a number of easy ways for humidity sensor performance judgment and inspection. Consistency test, the same type, the same manufacturer humidity Car Temperature Sensor preferably a purchase two or more products, the more illustrative, energized together comparator detects the output value, in a relatively stable condition, the consistency of observed test. If further testing, within 24h intervals between records within a day generally have high, medium and low three kinds of humidity and temperature conditions can be more comprehensive view of product consistency and stability, including temperature compensation feature. Breathe through your mouth, or use other means of Engine Water Temperature Sensor humidification humidification, observe its sensitivity, reproducibility, up off the wet wet performance, and resolution, the highest range of products and so on. Right product for the open box and closed box two cases tested. Comparison is consistent, the situation observed thermal effects. The product at high temperature and low temperature (according to the instructions standard) to be tested and restored to the normal state of the record before the experiment to detect and compare the test product temperature adaptability, and observe the product consistency condition. The performance of the final product quality inspection departments should be based on regular comprehensive means test. Using saturated salt solution for calibration, brand-name products can also be used for comparison testing, the product should be carried out during long-term use of a more comprehensive long-term calibration to determine the quality of the humidity sensor
