HDC1080: HDC1080 Sensor calibration after 1 year

Jagannath E

Part Number: HDC1080

i am using HDC1080 to measure Humidity and Temp, feel happy working with this sensor has it matches my requirement

i need an procedure or algorithm to write the code, to calibrate the sensor for std calibration value 11%, 53% and 90% RH value.

kindly guide me the algorithm, to write the code to my PIC controller.

Thanking you

Hi,
Sorry for the late reply.
The best and simplest way to calibrate the HDC1080 in 3 calibration points is to evaluate the RH% error in the 3 calibrations points and subtract the error in the micro-controller firmware. Instead for each of the two intervals between two calibration points (11-53 and 53-90) you can calculate the offset using a linear interpolation.
Please let me know if this replies to your question, or if you need further information.
Best regards,
Carmine
