Temperature and humidity sensor measurement considerations

First, select the range of measurements

As with measuring weight and temperature, the first choice of humidity sensor is to determine the range of measurement. Apart from meteorological and scientific research departments, temperature and humidity measurement and control generally do not need the full wet range of 0-99.9 RH measurements.


Second, select measurement accuracy

Measurement accuracy is the most important indicator of humidity sensors. Every increase of one percent is a step up or even a step up to a humidity sensor. Because to achieve different accuracy, the manufacturing costs vary greatly. The price is also very different. Therefore, users must tailor their clothes, not blindly pursue "high, fine, sharp." if humidity sensors are used at different temperatures, their indication also takes into account the effect of temperature drift. As we all know, Relative humidity is a function of temperature, which seriously affects the relative humidity in a given space. Each change in temperature
