What temperature sensors do you use? (lemm.ee)

I wanted some temperature sensor that can place outside my house, it is simple and not very expensive, which directly integrates with HA would be ideal but not 100% necessary.

I have seen these in Aliexpress, I don't know if someone has them or if you think they can serve me https://acortar.link/5vbeT2

Thanks for the aid, I am starting with all this and I see good resources in this community

EDIT: Thank you very much for all the answers, it is incredible how fast you have helped me. You have also given me many interesting options to investigate more before making a decision

I also soldered some myself. I'm currently using Bosch's BME280 and similar. Works well. Just don't bother with the old DHT11 sensors, in my experience they don't work well outdoors. But I'm not sure of OP prefers buying a proper product that doesn't require soldering and coding/configuring.

I never had dht-11s that worked at all. Maybe one in ten was anywhere close to calibrated correctly. I need to check out the bme280, though.

Yeah, there's a whole line of these sensors with BMPx80 and BMEx80 which include additional features, humidity, pressure, VoC... And I had my two or three DHT-11 work for some time. But mine also weren't very accurate. Plus the humidity measurement were always way off. And they'd get saturated and just show 100% a lot of the time. And i think two just stopped working over the years, I've replaced the last one, one or two years ago.
