I’ve recently purchased a BME680 breakout for my Raspberry Pi Zero W, which I wanted to use to measure temperature and pressure. When I started running the example, the first thing that surprised me was that the BME680 was reading 25 degrees in the apartment (even though, another room thermometer next to it said 19 degrees).
I thought it needed a bit of time to tune itself. However, after I left it to collect data for a couple of hours I have noticed that the temperature was actually increasing. It now records 30 degrees (it’s around 20 degrees in the flat now).
What could have cause the BME680 to show these readings?
