Hi,
we are experiencing some problems with humidity output of the HDC1080 sensor. The sensors were working properly for more than a month. then the problems began. After a longer period of high humidity exposure (RH% at 80 - 85, 2-3 days), the sensors output went to 0xFFFC and it is stuck there.
One of the problems might be our PCB. The HDC1080 is used as a substitute for a different sensor SI7020 (Silabs). We didn't change the PCB because our engineers thought they were pin to pin, but unfortunately it isn't so. In our case the pins 3,4 are connected to VDD (3V) and the DAP pad is connected to GND. Also the ceramic capacitor between VDD and GND in 1uF instead of 0.1 uF. Might this in any way affect the performance of the sensor or cause the problem we are experiencing?
Thanks in advance for your response.
