Hello,
I have used the Nordic Thingy application, I also used the Raspberry Pi Python interface and I observed the temperature measured.
The temperature is not stable and can go up to 1°C in 1 second then decrease. I don't understand where these measures are coming from.
The temperature and humidity sensor is the HTS221.
I have found here : https://learn.adafruit.com/adafruit-hts221-temperature-humidity-sensor
" The HTS221 can measure relative humidity from 0%-100% rH with a sensitivity of 0.004% and 3.5% accuracy. It can also measure temperature from -40 to 120 degrees C, with a resolution of 0.016°C with ±0.5 °C accuracy between 15 and +40 °C."
Best regards.
