How do I calibrate the Relative Humidity Sensor ...

· It is not usually necessary to perform a new calibration when using the Relative Humidity Sensor (RH-BTA). You can simply connect the sensor to a Vernier data-collection interface, start your Vernier data-collection program, and the stored calibration is used. If you do want to calibrate the Relative Humidity Sensor, you can do so by comparing it to another calibrated instrument that …

Test and Calibrate DHT22 / AM2302 / RHT03 hygrometers

· My apparatus contains no external reference against which to calibrate the temperature output and I therefore simply plot each sensor's offset from the mean of all six sensors. I am strictly only showing the difference between the sensors, but the absolute calibration looks likely to be good to ∼°C with a relative drift of <°C over a 30°C range. Repeatability for most of the sensors ...

How Hard Could That Be? Practical Humidity Calibration ...

70°C and 10% to 98% RH, an accuracy of ±% RH, and a temperature uniformity of ± °C., the system looked likely to help the Company forget all the difficulties of past systems. As with any calibration system, however, there were some surprises. The Company discovered during initial validation that the settling time of the chamber at programmed levels proved to be much longer than ...

Methods of Accurately Measuring Capacitive RH Sensors

Capacitive RH sensors have proven themselves to be a practical sensor technology in a wide variety of industrial applications. In its simplest form, a capacitor is formed when two conductive plates are separated by an insulator (dielectric). Figure 1 – Capacitor Structure The electrical capacitance is defined by the area of the plates, the distance between them and the dielectric coefficient ...
