Spikes

I have some unwanted spikes in value signal. Using it with MQTT/Homeassistant. Any suggestion on how to solve or the reason of those spikes?

I didn't have these ones so far. Could a piece of dust get into the sensor? Or this looks like around noon or after, could it be you've cooked? I baked and cooked some time ago and the sensor went off on that.
